Purpose: : The specific molecular mechanisms underlying age-related macular degeneration (AMD) are largely unknown. Fibulin 5 is an extracellular matrix protein abundantly expressed in tissues with enriched elastic fibers. This protein plays a critical role in the assembly and crosslinking of tropoelastin. Missense variations of fibulin 5 have been reported to occur exclusively in 1.7 percent of AMD patients (EM Stone et al, 2004, NEJM351:346-53). We characterized the distribution of fibulin 5 in healthy and diseased retina and, in vitro, investigated functional alterations of fibulin 5 due to missense variations found in AMD. Methods: : The expression of fibulin 5 in mouse retina and human macula was assessed by RT-PCR, immunohistochemistry and Western blotting. Expression constructs containing the seven variants (EM Stone et al, 2004, NEJM351:346-53) were generated by site-directed mutagenesis from the human fibulin-5 cDNA (generously provided by B. Schiemann). Secretion rates/levels of the ...
Helicases have important roles in nucleic acid metabolism, and their prominence is marked by the discovery of genetic disorders arising from disease-causing mutations. Missense mutations can yield unique insight to molecular functions and basis for disease pathology. XPB or XPD missense mutations le …
The orthologue of CLN3 in fission yeast is btn1. All disease-causing missense mutations of CLN3 were modelled in Btn1p, and their ability to rescue four defects of fission yeast cells lacking btn1 was assessed. Fission yeast cells deleted for btn1 have multiple defects, including larger vacuoles, a cytokinesis delay under normal growth conditions, cell curving and a failure to initiate polarised growth during growth at higher temperatures. None of the mutations associated with disease rescued all of the phenotypes assayed here, although many had a significant effect on one or more phenotype. Mutations of residues on the lumenal face of the protein almost completely ablated protein function. One of the defects, cell curving, was rescued only by the mutant corresponding to the disease-causing missense mutation p.Glu295Lys. Patients with this mutation have the mildest disease phenotype known for CLN3, with onset of blindness at the normal age but very delayed onset of other symptoms.. ...
Each persons genome sequence has thousands of missense variants. Practical interpretation of their functional significance must rely on computational inferences in the absence of exhaustive experimental measurements. Here we analyzed the efficacy of these inferences in 33 de novo missense mutations revealed by sequencing in first-generation progeny of N-ethyl-N-nitrosourea-treated mice, involving 23 essential immune system genes. PolyPhen2, SIFT, MutationAssessor, Panther, CADD, and Condel were used to predict each mutations functional importance, whereas the actual effect was measured by breeding and testing homozygotes for the expected in vivo loss-of-function phenotype. Only 20% of mutations predicted to be deleterious by PolyPhen2 (and 15% by CADD) showed a discernible phenotype in individual homozygotes. Half of all possible missense mutations in the same 23 immune genes were predicted to be deleterious, and most of these appear to become subject to purifying selection because few persist between
This study reports the results of in-depth analysis of 18 PSSM in samples from VWD patients. The novel and robust procedure used, combining two-step RT-PCR and NGS sequencing, was faster and more sensitive than the method used in our previous article.7 This new approach provides several advantages, such as allele-specific individual sequences, higher sensitivity to detect transcript variants present at low copy numbers, and simplified sample preparation. Moreover, the NGS data on total reads obtained for each transcript is additional information that can provide an approximation of the expression levels of each VWF mRNA. Studies are currently ongoing to confirm that the relative expression of each transcript obtained by NGS is comparable to that provided by real-time RT-PCR.. The proven usefulness of leukocyte analysis to interpret mutations masked by NMD in platelets was seen in relation to the c.3379+1G,A mutation, which had been previously investigated by RT-PCR in platelets.23 In that study, ...

The interplay between oxygen and iron is longstanding and central to all or any aerobic lifestyle. have investigated the partnership between iron availability, or insufficiency, and proliferative replies in configurations of relevance to PAH. In a single study the usage of iron chelation via the administration of desferrioxamine to rats was discovered to inhibit chronic hypoxia induced PH and redecorating recommending that iron is certainly essential for vascular proliferation in these situations; an assertion further backed by tests by the same writers which showed an iron chelation technique also inhibited proliferation of cultured PASMCs (Wong et al., 2012). In another scholarly study, usage of plumbagin, an iron chelator, (Padhye et al., 2012) was discovered to limit proliferation in individual PASMCs and lower distal pulmonary artery redecorating within a rat style of PAH (Courboulin et al., 2012). Additionally, iron was discovered to induce redecorating in cultured rat PAECs (Gorbunov et ...

We recently described a new autosomal dominant myopathy associated with a missense mutation in the myosin heavy chain (MyHC) IIa gene (MYH2). In this study, we performed mutation analysis of MYH2 in eight Swedish patients with familial myopathy of unknown cause. In two of the eight index cases, we identified novel heterozygous missense mutations in MYH2, one in each case: V970I and L1061V. The mutations were located in subfragment 2 of the MyHC and they changed highly conserved residues. Most family members carrying the mutations had signs and symptoms consisting mainly of mild muscle weakness and myalgia. In addition, we analyzed the extent and distribution of nucleotide variation in MYH2 in 50 blood donors, who served as controls, by the complete sequencing of all 38 exons comprising the coding region. We identified only six polymorphic sites, five of which were synonymous polymorphisms. One variant, which occurred at an allele frequency of 0.01, was identical to the L1061V that was also found ...
Maturity-onset diabetes of the young type 3 (MODY3) is a non-ketotic form of diabetes associated with poor insulin secretion. Over the past years, several studies have reported the association of missense mutations in the Hepatocyte Nuclear Factor 1 Alpha (HNF1A) with MODY3. Missense mutations in the POU homeodomain (POUH) of HNF1A hinder binding to the DNA, thereby leading to a dysfunctional protein. Missense mutations of the HNF1A were retrieved from public databases and subjected to a three-step computational mutational analysis to identify the underlying mechanism. First, the pathogenicity and stability of the mutations were analyzed to determine whether they alter protein structure and function. Second, the sequence conservation and DNA-binding sites of the mutant positions were assessed; as HNF1A protein is a transcription factor. Finally, the biochemical properties of the biological system were validated using molecular dynamic simulations in Gromacs 4.6.3 package. Two arginine residues ...
We report here the results of genetic studies on Müllerian aplasia, namely, results of TBX6 and LHX1 mutation screening in 112 MA patients and CNV analysis in a subset of them.. Sequencing of TBX6 (located in 16p11.2) revealed a splice mutation in two patients and rare missense variants in 15 patients (13.4%). TBX6 is a transcription factor that functions in early embryogenesis. It resides on the minus strand with a full-length transcript of 1806 bp, encoding a 436 aminoacid protein (NP_004599.2). TBX6 is a member of a phylogenetically well-conserved T-box gene family, where all members share the similar N-terminal DNA-binding domain, the T-box [55]. We identified a c.622-2A,T splice site mutation in two patients (one with MRKH and the other with total MA and with ovarian aplasia) and a rare homozygous missense variant in exon 4 and exon 6 in two patients. The splice site mutation is situated in the highly conserved splice acceptor site (AG) of exon 5. According to the in silico prediction ...

The p.Arg844Cys variant in the GRIN1 gene has been previously reported de novo in 4 individuals with features consistent with GRIN1-associated neurodevelopmental disorder (Lemke et al., 2016; Vanderver et al., 2016; Wang et al., 2019). This variant was absent from large population databases, including the Genome Aggregation Database (http://gnomad.broadinstitute.org/). The GRIN1 gene has fewer missense variants in the general population than expected. A low rate of missense variation may suggest that this gene is intolerant to missense variation. Computational tools predict that the p.Arg844Cys is deleterious; however, the accuracy of in silico algorithms is limited. These data were assessed using the ACMG/AMP variant interpretation guidelines. In summary, there is sufficient evidence to classify the p.Arg844Cys variant as pathogenic for autosomal dominant GRIN1-associated neurodevelopmental disorder based on the information above.

High blood pressure is a major risk factor for cardiovascular disease and premature death. However, there is limited knowledge on specific causal genes and pathways. To better understand the genetics of blood pressure, we genotyped 242,296 rare, low-frequency and common genetic variants in up to 192,763 individuals and used ~155,063 samples for independent replication. We identified 30 new blood pressure- or hypertension-associated genetic regions in the general population, including 3 rare missense variants in RBM47, COL21A1 and RRAS with larger effects (,1.5 mm Hg/allele) than common variants. Multiple rare nonsense and missense variant associations were found in A2ML1, and a low-frequency nonsense variant in ENPEP was identified. Our data extend the spectrum of allelic variation underlying blood pressure traits and hypertension, provide new insights into the pathophysiology of hypertension and indicate new targets for clinical intervention.. ...
M-CAP is the first pathogenicity classifier for rare missense variants in the human genome that is tuned to the high sensitivity required in the clinic (see Table). By combining previous pathogenicity scores (including SIFT, Polyphen-2 and CADD) with novel features and a powerful model, we attain the best classifier at all thresholds, reducing a typical exome/genome rare (,1%) missense variant (VUS) list from 300 to 120, while never mistaking 95% of known pathogenic variants as benign. Further details can be found here ...
Author Summary Intrinsically unstructured or disordered proteins have been implicated in the etiology of a wide spectrum of diseases. However, the molecular mechanisms that relate mutations in intrinsically disordered regions (IDRs) to disease pathogenesis have not been investigated. Disordered proteins do not conform to the prevailing view of deleterious mutations which equates function, structure and evolutionary conservation - intrinsically disordered regions are functional, but lack a fixed three-dimensional structure and in general have low sequence conservation. Here we demonstrate that |20% of disease-associated missense mutations affect IDRs and interfere with their functions. We further show that 20% of deleterious mutations in IDRs induce predicted disorder-to-order transitions. Our predictions are supported by accelerated molecular dynamics simulations that show an increase in helical propensity of the region harboring a disease disorder-to-order transition mutation of tumor protein p63. Our
In this study we analyzed the spectrum of HNF1A mutations in HCA and showed a significant difference in pattern in comparison with individuals with MODY3, both at the nucleotide and amino acid levels. In HCA, location of the mutations is very restricted because almost all of the truncating mutations led to the loss of the transactivation domain and the missense mutations altered mainly the POU-H domain. When we take into account the two largest series of HNF1A screening in MODY3 (21,25), only 48% of the germline mutations (117 of 720 are missense mutations in POU-H, and 227 of 720 are truncating mutations localized in the first 291 amino acids) fit the features of the HNF1A somatic mutations. This observation suggests that only a part of HNF1A mutations that are associated with diabetes could predispose to the development of a H-HCA.. Previous analysis of the MODY3 mutations showed that the age at onset of diabetes is modulated according to the position of the mutation relative to the HNF1A ...
It is widely accepted that genetic insults are indispensable in the formation of a frank tumor. In the development of human cutaneous SCCs, alterations in ras genes (10%-30% incidence) (3, 4) and the p53tumor suppressor gene (40%-50% incidence) (5, 6) have been most heavily implicated. While the majority of these lesions are missense mutations, the functional assessment of p53 missense mutations is complicated in that some give rise to a loss-of-function or null phenotype classically associated with tumor suppressor genes, whereas the majority of p53 missense mutations appear to result in a gain-of-function phenotype. While the presence of both types of p53 mutations in SCCs denotes a selection advantage to these genetic lesions, whether gain-of-function or loss-of-function mutations are more critical for SCC development is unclear. Therefore, the understanding of p53 phenotype status, i.e., tumor suppressive versus oncogenic, as it relates to SCC formation and progression is of paramount ...

PAX9, a paired domain transcription factor, has important functions in craniofacial and limb development. Heterozygous mutations of PAX9, including deletion, nonsense, or frameshift mutations that lead to a premature stop codon, and missense mutations, were previously shown to be associated with autosomal dominant oligodontia. Here, we report a novel missense mutation that lies in the highly conserved paired domain of PAX9 and that is associated with non-syndromic oligodontia in one family. The mutation, 83G-->C, is predicted to result in the substitution of arginine by proline (R28P) in the N-terminal subdomain of PAX9 paired domain. To rule out the possibility that this substitution is a rare polymorphism and to test whether the predicted amino acid substitution disrupts protein-DNA binding, we analyzed the binding of wild-type and mutant PAX9 paired domain to double-stranded DNA targets. The R28P mutation dramatically reduces DNA binding of the PAX9 paired domain and supports the hypothesis ...
Intractable severe diarrhea accompanied by phenotypic abnormalities and liver cirrhosis in infants is associated with THES. The prognosis of THES is poor, with ,25% of patients currently reported to succumb to mortality between the ages of 2-5 years, a proportion of which with early-onset cirrhosis. However, case reports have described improved survival rates, with long-term parenteral nutrition (PN)-dependency or PN weaning in certain cases. The patient described in the present study was considered to have THES, based on his intrauterine growth retardation, intractable diarrhea, facial dysmorphism, abnormal scalp hair shafts, trichorrhexis nodosa, immune disorders and liver cirrhosis.. Lee et al (11) isolated genomic clones and mapped the human homolog of the SKI2 gene to 6p21 using fluorescence in situ hybridization. Using genomic sequence analysis, Yang et al (12) determined that SKIV2L is a polymorphic gene, which spans 11 kb and contains 28 exons (11). Fabre et al (10) sequenced the ...
Purpose: To study the influence of Crb1 c.3481delC (rd8) mutation on the retinal phentoype of the L-ORD mouse model with heterozygous S163R missense mutation in the C1Q-Tumor Necrosis Factor Related Protein-5 (C1QTNF5/CTRP5) gene.. Methods: Mouse model for L-ORD was generated on C57BL/6J background and the presence of rd8 mutation was observed in this colony. To study the influence of the rd8 mutation on L-ORD phenotype, mouse lines carrying both the Ctrp5 S163R and the rd8 mutation (Ctrp5+/-;rd8/rd8), without the rd8 mutation (Ctrp5+/-;wt/wt); and wild type mice with and without the rd8 mutation (Wtrd8/rd8 and Wtwt/wt, respectively) were generated. Genotyping was carried out by allelic polymerase chain reaction (PCR) or sequencing. Retinal morphology was studied by fundus imaging, histology, light microscopy, electron microscopy and immunohistochemistry.. Results: Genotype analysis of the mice in L-ORD mouse colony detected the rd8 mutation in both the homozygous or heterozygous states. Fundus ...

This sequence change replaces glycine with arginine at codon 85 of the NPPA protein (p.Gly85Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine. This variant is present in population databases (rs749353276, ExAC 0.04%) but has not been reported in the literature in individuals with a NPPA-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In addition, the arginine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. However, algorithms developed to predict the effect of nucleotide changes on mRNA splicing suggest that this variant may alter mRNA splicing, but these predictions have not been confirmed by published transcriptional studies. In summary, this is a rare missense change with an ...
Results A novel missense mutation of A to G (p.Q286R) in patients with DDS (n=3/7) was found in the HOOK1 gene, which was inherited from the mother in one patient. This variant was absent in 160 fertile population-matched control individuals. Morphological observation showed that almost all the DDS broke into decaudated heads and headless tails at the implantation fossa or the basal plate. The clinical studies indicated that the mutation might cause reduced FRs on both ART (FR=18.07%) and interspecies ICSI (FR=16.98%). ...
The tiny heat shock protein (sHSP) B-crystallin (B) plays an integral role within the cellular protection system against stress. of the heterogeneity parameter because of this type of program. A system of multimerization into higher-order asymmetric oligomers via the addition as high as six dimeric Lenvatinib products to some 24-mer is suggested. The suggested asymmetric multimers clarify the homogeneous appearance of B in negative-stain EM pictures as well as the known powerful exchange of B subunits. The style of B offers a structural basis for understanding known disease-associated missense mutations and makes predictions regarding substrate binding as well as the reported fibrilogenesis of B. resonances of Tyr48 and Thr63 and between your 13Cresonance of Leu49 as well as the 13Cresonance of Asp62 and Thr63 and 13Cresonance of Phe61 additional corroborate the prediction and reveal an antiparallel orientation between your two strands (Fig.?2and Desk?S1). Even though chemical shift evaluation ...
Background: Escape mutations potentially allow viruses to avoid detection and clearance by the host immune sys-tem and may represent a mechanism through which infections may persist in some patients. The association of the mutations in the HBcAg gene with Hepatitis B asymptomatic carriers (ASC) has not been studied adequately. The current study was aimed to investigate HBcAg18-27 CTL epitope mutations in ASC patients in the South-Eastern region of Iran. Methods: 100 ASC patients were selected for this study and screened for HLA-A2 using flow cytometry. HBV-DNA was extracted from the HLA-A2 positive patients and the HBc gene was amplified using PCR. Direct double sequencing was performed to analyse mutations in the HBc gene of HBV isolates from patients with ASC. Results: Overall, 25 (25%) of individuals were HLA-A2 positive. Direct double sequencing indicated no mutations in the HBcAg18-27 epitope. However, four mutations within the T helper and three mutations within the B cell epitopes of ASC ...
Previous VHL mutation testing of germline DNA from the proband of family NCI-1326 was negative. However, the VHL and BAP1 genes are both on chromosome 3p so we asked whether somatic mutations in VHL could be detected in the tumors. VHL mutation analysis (Supplementary Materials and Methods) showed VHL mutation in some tumors (IV:1, Tumor 1 and IV:4, Tumor 1), but not in others (IV:1, Tumors 3 and 4; Supplementary Fig. S2 and data not shown). Thus, mutations in VHL and BAP1 may cooperate in the development of at least some tumors.. Together, these data suggest that the novel BAP1 p.L14H missense variant is the cause of the underlying cancer phenotype in the family described. First, the variant cosegregated with the RCC phenotype. Second, the variant targets the catalytic domain, which is a common site of missense mutations including pathogenic somatically-acquired mutations in neighboring residues pG13V and p.H144N. Third, L14 is highly conserved across species, and in silico analyses suggest ...
The steady advances in machine learning and accumulation of biomedical data have contributed to the development of numerous computational models that assess the impact of missense variants.

Predicting the deleteriousness of missense variants is extremely difficult. Variants whithin sites essential to protein function is an important criterion for variant pathogenicity prediction. However, for many proteins these essential sites have not been identified due to lack of statistical power and experimental data.. Here, we have developed a novel statistical framework to identify missense pathogenic enriched regions (PERs). We compare missense variant density identified in individuals of the general population (gnomAD, n= 2,219,811) against missense variant density retrieved from patient variant databases (ClinVar/HGMD, n = 76,153). To gain power, we grouped 9,990 genes into 2,871 gene families and evaluated the density of pathogenic variants across all members of the gene family.. We identified 464 PERs spanning 41,463 amino acids in 1,252 genes. In addition, gene-wise analysis was able to identify 251 additional PERs involving 2,639 amino acids. These regions can be effectively ...
These are internal identifiers that are unique to a mutation on a particular transcript and are displayed in the URL of the mutation pages. Therefore, several of these internal ids could be associated with a single genomic COSV id where the mutation has been mapped to all overlapping genes and transcripts. Similarly, since every COSM id is mapped to one COSV id (where genomic coordinates are known), each COSM id can also be associated with several alternative (internal) identifiers. These ids are expected to change between assemblies (GRCh37 and GRCh38) and between the releases ...

10,12 This could be a novel therapeutic strategy to target Aβ neurotoxicity in AD. Presenilin APP mutations result in only a small proportion of autosomal dominant inherited types of AD, which is why there have been so many linkage selleck kinase inhibitor studies of other loci with FAD. The observation of linkage with chromosomal region 14q in some FAD families eventually led to the discovery of a novel gene, namely presenilin 1 (PS1).73-76 The first PS1 mutation. associated with FAD was reported in 1995.73,77,78 Since then about 120 kinds of PS1 mutation have been reported in about 260 families around the world.

Coarctation of the aorta (CoA) accounts for 4-8% of congenital heart defects (CHDs) and carries substantial morbidity despite treatment. We performed a genome-wide association study (GWAS) of CoA among 120 Icelandic cases and 355,166 controls and found association with a rare (frequency = 0.34%) missense mutation p.Arg721Trp in MYH6 (odds ratio (OR) = 44.2, P = 5.0x10-22), encoding an essential sarcomere protein. Approximately 20% of CoA cases in Iceland carry p.Arg721Trp. This is the first mutation associated with non-familial or sporadic CoA at a population level. P.Arg721Trp also associates with risk of bicuspid aortic valve (BAV) and other CHDs and has been reported to have a broad effect on cardiac electrical function and to associate strongly with sick sinus syndrome (SSS) and atrial fibrillation (AF). These findings suggest that p.Arg721Trp in MYH6 causes a cardiac syndrome with highly variable expressivity, and emphasize the major importance of sarcomere integrity for cardiac development ...
Notch1 has been regarded as a fundamental regulator in tissue differentiation and stem cell properties. Recently, Notch1 mutations have been reported intensively both in solid tumors and in hematopoietic malignancies. However, little is known about the biological effect and the clinical implication of these reported mutations. Previously, we discovered several missense mutations in the Notch1 receptor in a Chinese population with oral squamous cell carcinoma (OSCC). We selected a hotspot mutation in the Abruptex domain (C1133Y). The expression of Notch1 was determined by western blot and real-time qPCR in OSCC cell lines transfected with pcDNA3.1-Notch1WT, pcDNA3.1-Notch1C1133Y, or pcDNA3.1 empty vector. CCK-8 assays were used to assess cell proliferation. Flow cytometry and western blot were used to confirm the alteration of cell cycle after transfection. Transwell assays and the detection of Epithelial-to-mesenchymal transition (EMT) markers were used to determine the invasive ability. The effects

Molecular anomalies in MED13L, leading to haploinsufficiency, have been reported in patients with moderate to severe intellectual disability (ID) and distinct facial features, with or without congenital heart defects. Phenotype of the patients was referred to MED13L haploinsufficiency syndrome. Missense variants in MED13L were already previously described to cause the MED13L-related syndrome, but only in a limited number of patients. Here we report 36 patients with MED13L molecular anomaly, recruited through an international collaboration between centers of expertise for developmental anomalies. All patients presented with intellectual disability and severe language impairment. Hypotonia, ataxia, and recognizable facial gestalt were frequent findings, but not congenital heart defects. We identified seven de novo missense variations, in addition to protein-truncating variants and intragenic deletions. Missense variants clustered in two mutation hot-spots, i.e., exons 15-17 and 25-31. We found that
In contrast to the typical Pierson syndrome phenotype, which has been associated primarily with null mutations in LAMB2,1,4 missense mutations, such as R246Q and C321R, cause mild variants of Pierson syndrome, in which congenital nephrotic syndrome is the predominant manifestation and extrarenal features are less pronounced.18 LAMB2 missense mutation is one of the most common disease-causing mutations in early onset nephrotic syndrome.39 Previously, we investigated the mechanisms whereby the R246Q mutation causes congenital nephrotic syndrome19; here, we determined how the C321R mutation causes proteinuria.. Our results suggest that the mechanisms responsible for nephrotic syndrome in patients harboring the C321R-LAMB2 mutation involve both severely impaired laminin secretion and concomitant podocyte ER stress-associated injury. Our hypothesis is supported by both in vivo and in vitro data. In vivo, we generated three lines of transgenic mice, in which C321R-LAMB2 mRNA was expressed in podocytes ...
Mutations in SLC6A1, encoding γ-aminobutyric acid (GABA) transporter 1 (GAT-1), have been recently associated with a spectrum of epilepsy syndromes, intellectual disability and autism in clinic. However, the pathophysiology of the gene mutations is far from clear. Here we report a novel SLC6A1 missense mutation in a patient with epilepsy and autism spectrum disorder and characterized the molecular defects of the mutant GAT-1, from transporter protein trafficking to GABA uptake function in heterologous cells and neurons. The heterozygous missense mutation (c1081C to A (P361T)) in SLC6A1 was identified by exome sequencing. We have thoroughly characterized the molecular pathophysiology underlying the clinical phenotypes. We performed EEG recordings and autism diagnostic interview. The patient had neurodevelopmental delay, absence epilepsy, generalized epilepsy, and 2.5-3 Hz generalized spike and slow waves on EEG recordings. The impact of the mutation on GAT-1 function and trafficking was evaluated by 3H
article{ad4911a9-fa37-43c8-88dd-95a7ab3e310d, abstract = {,p,ABHD12 mutations have been linked to neurodegenerative PHARC (polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and early-onset cataract), a rare, progressive, autosomal, recessive disease. Although ABHD12 is suspected to play a role in the lysophosphatidylserine and/or endocannabinoid pathways, its precise functional role(s) leading to PHARC disease had not previously been characterized. Cell and zebrafish models were designed to demonstrate the causal link between an identified new missense mutation p.T253R, characterized in ABHD12 from a young patient, the previously characterized p.T202I and p.R352* mutations, and the associated PHARC. Measuring ABHD12 monoacylglycerol lipase activity in transfected HEK293 cells demonstrated inhibition with mutated isoforms. Both the expression pattern of zebrafish abhd12 and the phenotype of specific antisense morpholino oligonucleotide gene knockdown morphants were consistent with human ...
ATM is the gene mutated in the autosomal recessive disorder Ataxiatelangiectasia (A-T). Female relatives of A-T patients carrying a heterozygous A-T mutation have an increased breast cancer risk but it was not known if ATM mutations that were not pathogenic for A-T were associated with breast cancer risk. In a large combined analysis, Fletcher and colleagues genotyped 5 polymorphic missense ATM SNPs in 26,101 breast cancer cases from 23 different studies. The authors report that the 5 missense ATM SNPs were associated with a small increased risk of breast cancer. This study illustrates how testing the combined effects of rare missense variants in known breast cancer genes can help clarify their overall contribution to breast cancer susceptibility. ...
In this study, systematic inhibitor response to ErbB missense mutations in gastric cancer (GC) is investigated by combining computational analysis and experimental assay. The response profile is created for 6 ATP-competitive, reversible inhibitors against 9, 17, 5 and 17 GC-associated missense mutations of ErbB1, ErbB2, ErbB3 and ErbB4 kinase domains, respectively. From the profile a number of p...
Homozygous mutations in TREM2 are known to cause rare, autosomal recessive forms of dementia with an early onset and presenting with[6] or without[8] bone cysts and fractures. A rare missense mutation (rs75932628-T) in the gene encoding TREM2, (predicted to result in an R47H substitution), confers a significant risk of Alzheimers disease. Given the reported antiinflammatory role of TREM2 in the brain, it is suspected of interfering with the brains ability to prevent the buildup of plaque.[9][10] TREM2 mutations increase the risk of neurodegenerative conditions such as Alzheimers disease, amyotrophic lateral sclerosis, and Parkinsons disease. TREM2 interacts with DAP12 in microglia to trigger phagocytosis of amyloid beta peptide and apoptotic neurons without inflammation. Mutations in TREM2 impair the normal proteolytic maturation of the protein which in turn interferes with phagocytosis and may therefore contribute to the pathogenesis of Alzheimers disease.[11] Soluble TREM2 has been ...
ACTB encodes β-actin, an abundant cytoskeletal housekeeping protein. In humans, postulated gain-of-function missense mutations cause Baraitser-Winter syndrome (BRWS), characterized by intellectual disability, cortical malformations, coloboma, sensorineural deafness, and typical facial features. To date, the consequences of loss-of-function ACTB mutations have not been proven conclusively. We describe heterozygous ACTB deletions and nonsense and frameshift mutations in 33 individuals with developmental delay, apparent intellectual disability, increased frequency of internal organ malformations (including those of the heart and the renal tract), growth retardation, and a recognizable facial gestalt (interrupted wavy eyebrows, dense eyelashes, wide nose, wide mouth, and a prominent chin) that is distinct from characteristics of individuals with BRWS. Strikingly, this spectrum overlaps with that of several chromatin-remodeling developmental disorders. In wild-type mouse embryos, β-actin expression ...
Although improvements in genetic analysis have greatly enhanced our understanding of the mechanisms behind pancreatitis, it continues to afflict many families for whom the hereditary factors remain unknown. Recent evaluation of a patient with a strong family history of pancreatitis prompted us to reexamine a large kindred originally reported over 50 years ago with an autosomal-dominant inheritance pattern of chronic pancreatitis, diabetes, and pancreatic adenocarcinoma. Whole-exome sequencing analysis identified a rare missense mutation in the gene encoding pancreas-specific protease elastase 3B (CELA3B) that cosegregates with disease. Studies of the mutant protein in vitro, in cell lines, and in CRISPR-Cas9-engineered mice indicate that this mutation causes translational upregulation of CELA3B, which, upon secretion and activation by trypsin, leads to uncontrolled proteolysis and recurrent pancreatitis. Although lesions in several other pancreatic proteases have been previously linked to ...

Congenital heart defects (CHDs) are the most common birth defect worldwide and are a leading cause of neonatal mortality. Nonsyndromic atrioventricular septal defects (AVSDs) are an important subtype of CHDs for which the genetic architecture is poorly understood. We performed exome sequencing in 13 parent-offspring trios and 112 unrelated individuals with nonsyndromic AVSDs and identified five rare missense variants (two of which arose de novo) in the highly conserved gene NR2F2, a very significant enrichment (p = 7.7 × 10(-7)) compared to 5,194 control subjects. We identified three additional CHD-affected families with other variants in NR2F2 including a de novo balanced chromosomal translocation, a de novo substitution disrupting a splice donor site, and a 3 bp duplication that cosegregated in a multiplex family. NR2F2 encodes a pleiotropic developmental transcription factor, and decreased dosage of NR2F2 in mice has been shown to result in abnormal development of atrioventricular septa. Via
BACKGROUND: Genetic testing for breast cancer susceptibility is widely used, but for many genes, evidence of an association with breast cancer is weak, underlying risk estimates are imprecise, and reliable subtype-specific risk estimates are lacking. METHODS: We used a panel of 34 putative susceptibility genes to perform sequencing on samples from 60,466 women with breast cancer and 53,461 controls. In separate analyses for protein-truncating variants and rare missense variants in these genes, we estimated odds ratios for breast cancer overall and tumor subtypes. We evaluated missense-variant associations according to domain and classification of pathogenicity. RESULTS: Protein-truncating variants in 5 genes (ATM, BRCA1, BRCA2, CHEK2, and PALB2) were associated with a risk of breast cancer overall with a P value of less than 0.0001. Protein-truncating variants in 4 other genes (BARD1, RAD51C, RAD51D, and TP53) were associated with a risk of breast cancer overall with a P value of less than 0.05 ...
The consequences of base substitution mutations in protein coding regions of a gene depend on the substitution and its location. They may be silent, not resulting in a new amino acid in the protein sequence, eg. GCA or GCG codons in mRNA both mean arginine [this is often true in the third position of a codon, especially with transitions because of wobble base pairing]. A base substitution could also result in an amino acid substitution; this is referred to as a missense mutation. For example, CTC in the DNA sense strand [GAG in mRNA] will specify a glutamate residue in the protein; this is altered to CAC in the DNA or GUG in the mRNA, resulting in a valine residue in the beta-globin protein chain causing sickle-cell anemia. Missense mutations may have very serious consquences, as in the case of sickle-cell anemia, mild consequences as in the case of hemoglobin C (a different amino acid substitution in position 6 of beta-globin) or no phenotype as in the case of two known amino acid ...
We developed a sequence context based model of de novo mutations to create per-gene probabilities of mutation. We noticed a high correlation (0.94) between the probability of a synonymous mutation in a gene and the number of rare synonymous variants identified in that same gene first using the NHLBI. s Exome Sequencing Project data (evs.gs.washington.edu), then with 25,000 exomes analyzed simultaneously (see abstract by MacArthur et al). We predicted the number of variants that we would expect to see in the dataset and, in order to quantify deviations, created a Z score of the chi-squared difference between observation and expectation for both synonymous and missense variation. While the distribution of these Z scores for the synonymous variants was normal, there is a marked shift in the missense distribution towards having fewer variants than predicted ...
With increasing use of multi-gene panel tests, one of the genes in which mutations are frequently detected among breast cancer patients and others is the CHEK2 gene. This gene has been shown to have a 2-3 fold excess risk for breast cancer. There are many CHEK2 mutations that have been identified that generally fall into two broad categories: those that prematurely shorten the protein that is made from the gene (called truncating mutations) and those that change a single base pair within the gene that impairs it from working normally (called missense mutations). Most completed studies have focused on a specific truncating mutation called 1100delC, as it is a relatively common change particularly among European populations.. A few studies have tried to assess if breast cancers associated with CHEK2 mutations may have specific characteristics, although results have not been consistent. For example, a study from 2014 which included 3 CHEK2 truncating mutations (including the 1100delC ...
The horizontal axis represents time, and the vertical axis represents a percentage of the population. When a mutation enters the population, it occurs in only one individual and is plotted as a point somewhere on the x axis. If the mutation is passed on, for example to four new offspring, then it will be in a higher percentage of the population at the next time step. Most mutations will soon drop out of the population. Either the individual where the mutation originates will not survive, or if it does survive and mate, by chance it may not pass the mutation to its children. Even then the children may not pass the mutation any further. Mutations that eventually die out show up as inverted ``V shapes in the figure: they are introduced, they are passed on to some proportion of the population in the next few generations, and eventually the percentage drops to 0 as the mutation disappears. Some small percentage of new mutations are passed on successfully. If by chance the mutation continues to ...
Six novel missense mutations (H29D, L35P, G84R, C96S, S101C, and Y103C) were identified in seven families. Three of these mutations involve cysteine residues within the insulin A chain and are therefore predicted to affect the normal folding of the proinsulin molecule. S101C was identified in two families: in ISPAD180 the finding that both children are heterozygous for the mutation but neither parent is a carrier suggests that the mutation has arisen de novo in one parent who must be a germline mosaic (Fig. 2). In the second family, the mutation was not present in the unaffected father, but DNA was not available from the mother.. The novel C96S mutation occurs at the site of a previously reported mutation (C96Y) identified in a patient with PND (10) and in the Akita mouse model (11). The same amino acid substitution (Cys,Ser) is present at the adjacent residue (C95S) in the Munich mouse model (23). Studies of these mice indicate that mutant proinsulin is trapped and accumulated in the ER, ...

Family history showed that the patients father had developed muscle weakness and atrophy in his upper extremities at 50 years of age, and died of pneumonia at 72 years of age. However, her mother was healthy and died of chronic renal failure at 80 years of age. Her elder sister was, at the time of writing, 73 years of age and healthy. Her elder brother displayed muscle weakness and wasting in his upper limbs and was diagnosed with ALS at 46 years of age. He also had mild cognitive impairment 10 years after onset. He died from respiratory failure 15 years after symptom onset. Her younger sister developed weakness in her right hand at 50 years of age. She was diagnosed with ALS at 58 years of age. There are no affected members in the third generation of this family; however, they are all younger than 35 years of age.. A novel missense mutation (C to A codon 41 in exon 2) that resulted in an amino acid substitution of glycine to aspartate (G41D) was identified in participants II-2, II-3, II-4, ...
Description: Goniodysgenesis (GG) is caused by abnormal development of the anterior chamber of the eye. Due to abnormal development of intraocular fluid egress channels inside the eye the iridocorneal angle (ICA), through which the excessive chamber fluid is filtered and drained. Within dog, population goniodysgenesis is considered as a congenital disease, which can often cause glaucoma or blindness. For first was GG detected in Border Collies in the late 90s in Australia, after that it spread to Europe and USA.. Goniodysgenesis has two forms: severe and mild. The severe form of this disease is caused by the mutation in the gene encoding for olfactomedin-like 3 (OLFML3). This encoded protein facilitates protein-protein interactions, cell adhesion, and intracellular interactions and has a general supporting function. It seems that the mild form of the disease is not associated with this mutation and can be caused by other genetic predispositions. GG is caused by a missense mutation c.590G,A ...

For position 29 only BLOSSUM62 says that this mutation is not likely. The 9 other sources show that this mutation wont have a damaging influence on the function or structure of the protein. This is perspicuous since the conservation of this position is not very high. The amino acid on position 125 is quite good conserved with 96%. SNAP and SIFT says that this mutation will have an influence on the protein whereas Polyphen2 says that this mutation is ether not (HumVar) or hardly damaging (HumDiv). Since this position is quite good conserved it is more likely that this mutation will have an influence on the function or structure of the protein. back to Maple_syrup_urine_disease main page go back to Task 5 Mapping SNPs ...

In this rar are the contents of the hdd mutation sits on. It contains the current (non-functioning) source code as well as multiple source backups I had made throughout its development. The current source code is capable of importing tags from other projects, but when I last touched it I was in the middle of writing code to explode the sound_diagnostics tag at decompile time, and rebuilding it at compile time from the sound tags. So in its current state it will not work for anything, if it even compiles without errors. I would check the last source backup to see if it can import tags, since it could prove useful to some people. I would also like to say that this project is the result of many years of work, coding styles, and ideas. It is a mess and does not reflect my current coding ability. My only request is that if you choose to do anything to Mutation and release it, please release it under another name with credit to the mutation source code.

A) in a published family with nonsyndromic MR, MRX13. This change occurs in a highly conserved amino acid, with proline (P) being substituted by threonine (T) (p.P544T). Functional analysis shows that this amino-acid substitution compromises both tri- and didemethylase activity of the JARID1C protein. We conclude that the two novel changes impair JARID1C protein function and are disease-causing mutations in these families ...
