At least 24 mutations in the POMT1 gene have been found to cause Walker-Warburg syndrome, the most severe form of a group of disorders known as congenital muscular dystrophies. Individuals with Walker-Warburg syndrome have skeletal muscle weakness and abnormalities of the brain and eyes. Because of the severity of the problems caused by this condition, affected individuals usually do not survive past early childhood.. POMT1 gene mutations that cause Walker-Warburg syndrome lead to the formation of nonfunctional POMT enzyme complexes that cannot transfer mannose to α-dystroglycan, preventing its normal glycosylation. As a result, α-dystroglycan can no longer effectively anchor cells to the proteins and other molecules that surround them. Without functional α-dystroglycan to stabilize the muscle fibers, they become damaged as they repeatedly contract and relax with use. The damaged fibers weaken and die over time, which affects the development, structure, and function of skeletal muscles in ...

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that may be involved in the presentation of the laminin-binding O-linked carbohydrate chain of alpha-dystroglycan (a-DG), which forms transmembrane linkages between the extracellular matrix and the exoskeleton. Some pathogens use this O-linked carbohydrate unit for host entry. Loss of function compound heterozygous mutations in this gene were found in a human patient affected by the Walker-Warburg syndrome (WWS) phenotype. Mice lacking this gene contain misplaced neurons (heterotopia) in some regions of the brain, possibly from defects in neuronal migration. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2013 ...

Glycosylation is the most frequent modification of proteins and is important for many ligand-receptor interactions. Recently, defects in protein glycosylation have been linked to several forms of congenital muscular dystrophy that are frequently associated with brain abnormalities. Muscle-eye-brain disease and Walker-Warburg syndrome are caused by mutations in enzymes involved in O-mannosylation, whereas Fukuyama congenital muscular dystrophy and congenital muscular dystrophy type 1C are caused by mutations in genes that encode putative glycosyltransferases. The common factor in these disorders is defective processing and maturation of a protein called adystroglycan. This is thought to disrupt the link between a-dystroglycan and components of the extracellular matrix, and result in muscle disease and, in many cases, a neuronal-migration disorder.. ...

Muscle-eye-brain disease is an autosomal recessive disease characterized by mental retardation, muscular dystrophy, retinal hypoplasia and brain abnormalities. MEB disease belongs to the group of inherited congenital muscular dystrophies (CMDs) and presents a close resemblance to Fukuyama congenital muscular dystrophy (FCMD) and Walker-Warburg congenital muscular dystrophy.

Fukuyama-type congenital muscular dystrophy (FCMD), one of the most common autosomal recessive disorders in the Japanese population, is characterized by congenital muscular dystrophy in combination with cortical dysgenesis (micropolygyria). Recently, we identified, on chromosome 9q31, the gene responsible for FCMD, which encodes a novel 461 amino acid protein which we have termed fukutin. Most FCMD-bearing chromosomes examined to date (87%) have been derived from a single ancestral founder, whose mutation consisted of a 3 kb retrotransposal insertion in the 3′ non-coding region of the fukutin gene. FCMD is the first human disease known to be caused primarily by an ancient retrotransposal integration. We undertook a systematic analysis of the FCMD gene in 107 unrelated patients, and identified four novel non-founder mutations in five of them: one missense, one nonsense, one L1 insertion and a 1 bp insertion. The frequency of severe phenotypes, including Walker-Walberg syndrome-like ...

Dystroglycan ligand with other proteins is essential. Glycosylation of dystroglycan is necessary for its ligand binding activity. Mutations in glycosyltransferase enzymes cause abnormal glycosylation of dystroglycan. This hypoglycosylation is associated with less binding with other proteins and causes some congenital muscular dystrophy. Pikachurin is the most recently identified dystroglycan ligand protein and is localized in the synaptic cleft in the photoreceptor ribbon synapse. The binding between dystroglycan and pikachurin requires divalent cations. Ca2+ produces strongest binding; Mn2+ produces only faint bindings and no binding with Mg2+ alone. Dystroglycan has different domains that allow multiple Ca2+ sites to form a stable pikachurin-dystroglycan connection. This shows that pikachurin can form oligomeric structures; and suggests the possibility of clustering effects can be important in modulating pikachurin-dystroglycan interactions. Another thing to be considered is that the presence ...

Various muscular dystrophies are associated with the defective glycosylation of alpha-dystroglycan and are known to result from mutations in genes encoding glycosyltransferases. Fukutin-related protein (FKRP) was identified as a homolog of fukutin, the defective protein in Fukuyama-type congenital muscular dystrophy (FCMD), that is thought to function as a glycosyltransferase. Mutations in FKRP have been linked to a variety of phenotypes including Walker-Warburg syndrome (WWS), limb girdle muscular dystrophy (LGMD) 2I and congenital muscular dystrophy 1C (MDC1C). Zebrafish are a useful animal model to reveal the mechanism of these diseases caused by mutations in FKRP gene. Downregulating FKRP expression in zebrafish by two different morpholinos resulted in embryos which had developmental defects similar to those observed in human muscular dystrophies associated with mutations in FKRP. The FKRP morphants showed phenotypes involving alterations in somitic structure and muscle fiber organization, ...

WIN International, the worlds leading association in market research and polling, has published the Annual WIN World Survey (WWS - 2019). The WWS explores the views and beliefs of 29575 people from 40 countries across the globe on their quality of life and the populations mood. The main goal of the WWS is to investigate thoughts, expectations, worries, and perceptions related to relevant topics for society and business. It becomes clear how all of these can change in times of crisis, like the one we are living right now.. The spread of COVID-19, besides presenting many challenges to the health care systems and to the economic structure of many countries, it also deeply impacts society at so many levels.. The WWS data were collected between October and December 2019, and the interesting results entailing quality of life and the populations general mood are probably the most affected now.

Oculocutaneous albinism (OCA) is caused by a group of genetically heterogeneous inherited defects that result in the loss of pigmentation in the eyes, skin and hair. Mutations in the TYR, OCA2, TYRP1 and SLC45A2 genes have been shown to cause isolated OCA. No comprehensive analysis has been conducted to study the spectrum of OCA alleles prevailing in Pakistani albino populations. We enrolled 40 large Pakistani families and screened them for OCA genes and a candidate gene, SLC24A5. Protein function effects were evaluated using in silico prediction algorithms and ex vivo studies in human melanocytes. The effects of splice-site mutations were determined using an exon-trapping assay. Screening of the TYR gene revealed four known (p.Arg299His, p.Pro406Leu, p.Gly419Arg, p.Arg278*) and three novel mutations (p.Pro21Leu, p.Cys35Arg, p.Tyr411His) in ten families. Ex vivo studies revealed the retention of an EGFP-tagged mutant (p.Pro21Leu, p.Cys35Arg or p.Tyr411His) tyrosinase in the endoplasmic reticulum (ER) at

Beta-1,3-N-acetylgalactosaminyltransferase that synthesizes a unique carbohydrate structure, GalNAc-beta-1-3GlcNAc, on N- and O-glycans. Has no galactose nor galactosaminyl transferase activity toward any acceptor substrate. Involved in alpha-dystroglycan (DAG1) glycosylation: acts coordinately with GTDC2/POMGnT2 to synthesize a GalNAc-beta3-GlcNAc-beta-terminus at the 4-position of protein O-mannose in the biosynthesis of the phosphorylated O-mannosyl trisaccharide (N-acetylgalactosamine-beta-3-N-acetylglucosamine-beta-4-(phosphate-6-)mannose), a carbohydrate structure present in alpha-dystroglycan, which is required for binding laminin G-like domain-containing extracellular proteins with high affinity.

Fukutin related protein (FKRP) helps to glycosolate a-dystroglycan, a component of the DGC. Two murine lines were recently generated with knock-in mutations in FKRP. The first, FKRPTyr307Asn , has a point mutation common to human patients with LGMD2I and other FKRP mutation diseases. However, FKRPTyr307Asn mice did not have any discernable abnormal phenotype. The second line, FKRP-NeoTyr307Asn, has a missense mutation with a retained neomycin selection cassette, which results in a null allele. Homozygous mice with this mutation showed reduced levels of FKRP transcripts and perinatal fatality. Histology of muscle demonstrates edema and hypogly-cosylation of a-dystroglycan. Other phenotypic abnormalities found in this model affect the eye and brain in a manner similar to other diseases with alterations in FKRP (Ackroyd et al. 2009). These two lines will aid in the elucidation the function of FKRP in muscle cell biology and its role in eye and brain development.. ...

Three of these genes are clearly involved in the process of O-mannosylation (POMT1, POMT2, POMGnT1) (20, 24, 25), while the function of the remaining 3 genes, fukutin, FKRP and LARGE is still not clear (26-29). Of these 6 genes, the most frequently mutated in the Caucasian population is FKRP. While this was the first gene to be associated with an extremely wide range of clinical severity, more recent data suggests that this is also a common theme for mutations in other genes. The FKRP gene Our group originally described mutations in the fukutin-related protein gene (FKRP) in patients with a form of CMD (MDC1C) characterized by onset at. birth or in the first few months of life with profound weakness, markedly Inhibitors,research,lifescience,medical elevated Inhibitors,research,lifescience,medical serum CK and inability to achieve independent ambulation or standing (22).

Limb-girdle muscular dystrophy type 2O (LGMD2O) belongs to a group of rare muscular dystrophies named dystroglycanopathies, which are characterized molecularly by hypoglycosylation of alpha-dystroglycan (alpha-DG). Here, we describe the first dystroglycanopathy patient carrying an alteration in the promoter region of the POMGNT1 gene (protein O-mannose beta-1,2-N-acetylglucosaminyltransferase 1), which involves a homozygous 9-bp duplication (-83_-75dup). Analysis of the downstream effects of this mutation revealed a decrease in the expression of POMGNT1 mRNA and protein because of negative regulation of the POMGNT1 promoter by the transcription factor ZNF202 (zinc-finger protein 202). By functional analysis of various luciferase constructs, we localized a proximal POMGNT1 promoter and we found a 75% decrease in luciferase activity in the mutant construct when compared with the wild type. Electrophoretic mobility shift assay (EMSA) revealed binding sites for the Sp1, Ets1 and GATA transcription ...

Fukuyama congenital muscular dystrophy is an inherited condition that predominantly affects the muscles, brain, and eyes. Congenital muscular dystrophies are a group of genetic conditions that cause muscle weakness and wasting (atrophy) beginning very early in life.. Fukuyama congenital muscular dystrophy affects the skeletal muscles, which are muscles the body uses for movement. The first signs of the disorder appear in early infancy and include a weak cry, poor feeding, and weak muscle tone (hypotonia). Weakness of the facial muscles often leads to a distinctive facial appearance including droopy eyelids (ptosis) and an open mouth. In childhood, muscle weakness and joint deformities (contractures) restrict movement and interfere with the development of motor skills such as sitting, standing, and walking.. Fukuyama congenital muscular dystrophy also impairs brain development. People with this condition have a brain abnormality called cobblestone lissencephaly, in which the surface of the brain ...

At least 30 different types of CMD are now recognized (see the Types of CMD chart). At first glance, the various types of CMD seem to have little in common other than their early onset. But on the molecular level, the types can be grouped how their faulty protein affects cells. A very small group of CMDs are linked to proteins that affect what happens inside muscle fibers, affecting how the fibers process signals from the nervous system, for example, or how they handle calcium.

Keflezighi and his family were refugees[5] from Eritrea, who came to the United States via Italy in 1987. He is one of ten children.[6]. Meb was born in Eritrea on May 5, 1975, the third son of Russom and Awetash Keflezighi. At the time, Eritrea was embroiled in an often-brutal 30-yr war for liberation from Ethiopia (Eritrea finally achieved independence in 1993), and Russom was a liberation supporter. This meant that he sometimes had to leave his home in Adi Beyani to escape Ethiopian soldiers and their brutal massacres. Meb recalls that his childhood included regular encounters with death and dismemberment of his Eritrean friends and neighbors. He didnt see a car until he was 10 yrs old. Thinking it a death machine, he took flight. That was one of the races I lost, he once told the NY Times. Awetash feared that her husband would be killed, and eventually convinced him to flee Ethiopia for a better life. He ended up in Milan, Italy, for 5 yrs, sending money home until he could afford to ...
