An autosomal recessive neurodegenerative disorder characterized by the onset in infancy of an exaggerated startle response, followed by paralysis, dementia, and blindness. It is caused by mutation in the alpha subunit of the HEXOSAMINIDASE A resulting in lipid-laden ganglion cells. It is also known as the B variant (with increased HEXOSAMINIDASE B but absence of hexosaminidase A) and is strongly associated with Ashkenazic Jewish ancestry.
A mammalian beta-hexosaminidase isoform that is a heteromeric protein comprized of both hexosaminidase alpha and hexosaminidase beta subunits. Deficiency of hexosaminidase A due to mutations in the gene encoding the hexosaminidase alpha subunit is a case of TAY-SACHS DISEASE. Deficiency of hexosaminidase A and HEXOSAMINIDASE B due to mutations in the gene encoding the hexosaminidase beta subunit is a case of SANDHOFF DISEASE.
A hexosaminidase specific for non-reducing N-acetyl-D-hexosamine residues in N-acetyl-beta-D-hexosaminides. It acts on GLUCOSIDES; GALACTOSIDES; and several OLIGOSACCHARIDES. Two specific mammalian isoenzymes of beta-N-acetylhexoaminidase are referred to as HEXOSAMINIDASE A and HEXOSAMINIDASE B. Deficiency of the type A isoenzyme causes TAY-SACHS DISEASE, while deficiency of both A and B isozymes causes SANDHOFF DISEASE. The enzyme has also been used as a tumor marker to distinguish between malignant and benign disease.

Estimating the effective number of breeders from heterozygote excess in progeny. (1/1398)

The heterozygote-excess method is a recently published method for estimating the effective population size (Ne). It is based on the following principle: When the effective number of breeders (Neb) in a population is small, the allele frequencies will (by chance) be different in males and females, which causes an excess of heterozygotes in the progeny with respect to Hardy-Weinberg equilibrium expectations. We evaluate the accuracy and precision of the heterozygote-excess method using empirical and simulated data sets from polygamous, polygynous, and monogamous mating systems and by using realistic sample sizes of individuals (15-120) and loci (5-30) with varying levels of polymorphism. The method gave nearly unbiased estimates of Neb under all three mating systems. However, the confidence intervals on the point estimates of Neb were sufficiently small (and hence the heterozygote-excess method useful) only in polygamous and polygynous populations that were produced by <10 effective breeders, unless samples included > approximately 60 individuals and 20 multiallelic loci.  (+info)

Mutations in the organic cation/carnitine transporter OCTN2 in primary carnitine deficiency. (2/1398)

Primary carnitine deficiency is an autosomal recessive disorder of fatty acid oxidation caused by defective carnitine transport. This disease presents early in life with hypoketotic hypoglycemia or later in life with skeletal myopathy or cardiomyopathy. The gene for this condition maps to 5q31.2-32 and OCTN2, an organic cation/carnitine transporter, also maps to the same chromosomal region. Here we test the causative role of OCTN2 in primary carnitine deficiency by searching for mutations in this gene in affected patients. Fibroblasts from patients with primary carnitine deficiency lacked mediated carnitine transport. Transfection of patient's fibroblasts with the OCTN2 cDNA partially restored carnitine transport. Sequencing of the OCTN2 gene revealed different mutations in two unrelated patients. The first patient was homozygous (and both parents heterozygous) for a single base pair substitution converting the codon for Arg-282 to a STOP codon (R282X). The second patient was a compound heterozygote for a paternal 1-bp insertion producing a STOP codon (Y401X) and a maternal 1-bp deletion that produced a frameshift creating a subsequent STOP codon (458X). These mutations decreased the levels of mature OCTN2 mRNA and resulted in nonfunctional transporters, confirming that defects in the organic cation/carnitine transporter OCTN2 are responsible for primary carnitine deficiency.  (+info)

Novel mutation of the P0 extracellular domain causes a Dejerine-Sottas syndrome. (3/1398)

A patient is described with a Dejerine-Sottas syndrome caused by a novel heterozygous Cys(98)Tyr mutation in the extracellular domain of the major peripheral myelin protein zero (P0ex). Homotypical interactions between P0ex tetramers of apposed extracellular faces of the Schwann cell membrane play a crucial part in myelin compaction. The amino acid change disrupts a unique disulphide bond that stabilises the immunoglobulin-like structure of P0ex and it is predicted to cause severe dehypomyelination through dominant negative effects on the wild type protein.  (+info)

Requirement for the c-Maf transcription factor in crystallin gene regulation and lens development. (4/1398)

The vertebrate lens is a tissue composed of terminally differentiated fiber cells and anterior lens epithelial cells. The abundant, preferential expression of the soluble proteins called crystallins creates a transparent, refractive index gradient in the lens. Several transcription factors such as Pax6, Sox1, and L-Maf have been shown to regulate lens development. Here we show that mice lacking the transcription factor c-Maf are microphthalmic secondary to defective lens formation, specifically from the failure of posterior lens fiber elongation. The marked impairment of crystallin gene expression observed is likely explained by the ability of c-Maf to transactivate the crystallin gene promoter. Thus, c-Maf is required for the differentiation of the vertebrate lens.  (+info)

Iron overload in porphyria cutanea tarda. (5/1398)

BACKGROUND AND OBJECTIVE: Porphyria cutanea tarda (PCT) is a disorder of porphyrin metabolism associated with decreased activity of uroporphyrinogen decarboxylase (URO-D) in the liver. The relevance of iron in the pathogenesis of PCT is well established: iron overload is one of the factors that trigger the clinical manifestations of the disease and iron depletion remains the cornerstone of therapy for PCT. A role for genetic hemochromatosis in the pathogenesis of iron overload in PCT has been hypothesized in the past but only after the recent identification of the genetic defect causing hemochromatosis has the nature of this association been partially elucidated. This review will outline current concepts of the pathophysiology of iron overload in PCT as well as recent contributions to the molecular epidemiology of hemochromatosis defects in PCT. EVIDENCE AND INFORMATION SOURCES: The authors of the present review have a long-standing interest in the pathogenesis, etiology and epidemiology of iron overload syndromes. Evidence from journal articles covered by the Science Citation Index(R) and Medline(R) has been reviewed and collated with personal data and experience. STATE OF THE ART AND PERPECTIVES: Mild to moderate iron overload plays a key role in the pathogenesis of PCT. The recent identification of genetic mutations of the hemochromatosis gene (HFE) in the majority of patients with PCT confirms previous hypotheses on the association between PCT and hemochromatosis, allows a step forward in the understanding of the pathophysiology of the disturbance of iron metabolism in the liver of PCT patients, and provides an easily detectable genetic marker which could have a useful clinical application. Besides the epidemiological relevance of the association between PCT and hemochromatosis, however, it remains to be fully understood how iron overload, and in particular the cellular modifications of the iron status secondary to hemochromatosis mutations, affect the activity of URO-D, and how the altered iron metabolism interacts with the other two common triggers for PCT and etiological agents for the associated liver disease: alcohol and hepatitis viruses. The availability of a genetic marker for hemochromatosis will allow some of these issues to be addressed by studying aspects of porphyrins and iron metabolism in liver samples obtained from patients with PCT, liver disease of different etiology and different HFE genotypes, and by in vitro studies on genotyped cells and tissues.  (+info)

The obese gene is expressed in lean littermates of the genetically obese mouse (C57BL/6J ob/ob). (6/1398)

Some individuals of the mixed group of "lean" littermates (+/ob and +/+) of (C57BL/6J ob/ob) often suggest phenotypic characteristics of ob/ob animals. Therefore, it was of interest to determine whether expression of the ob gene had physiological significance in +/ob animals. Body weight (BW), fasting blood glucose (FBG), and body core temperature (Tr) were monitored between 62 and 364 days of age in +/+ and +/ob mice. Among females but not males, +/ob mice were heavier (P = 0.003) and FBG levels were greater (P = 0.04) than in +/+ animals. Comparison of Tr indicated differences suggesting falling Tr in +/ob but rising Tr in +/+ mice with age in males but not females. Multivariate analysis of variance yielded genotype effects for both males (P = 0.002) and females (P = 0.02). BW, FBG, and Tr alone were sufficient at the 75% level for genotypic characterization and separation of +/? animals as +/ob or +/+; clearly, expression of the ob gene in heterozygotes of the +/ob animal may make the mixed +/? group inappropriate as lean controls.  (+info)

Quantitative analysis of survival motor neuron copies: identification of subtle SMN1 mutations in patients with spinal muscular atrophy, genotype-phenotype correlation, and implications for genetic counseling. (7/1398)

Problems with diagnosis and genetic counseling occur for patients with autosomal recessive proximal spinal muscular atrophy (SMA) who do not show the most common mutation: homozygous absence of at least exon 7 of the telomeric survival motor neuron gene (SMN1). Here we present molecular genetic data for 42 independent nondeleted SMA patients. A nonradioactive quantitative PCR test showed one SMN1 copy in 19 patients (45%). By sequencing cloned reverse-transcription (RT) PCR products or genomic fragments of SMN1, we identified nine different mutations in 18 of the 19 patients, six described for the first time: three missense mutations (Y272C, T274I, S262I), three frameshift mutations in exons 2a, 2b, and 4 (124insT, 241-242ins4, 591delA), one nonsense mutation in exon 1 (Q15X), one Alu-mediated deletion from intron 4 to intron 6, and one donor splice site mutation in intron 7 (c.922+6T-->G). The most frequent mutation, Y272C, was found in 6 (33%) of 18 patients. Each intragenic mutation found in at least two patients occurred on the same haplotype background, indicating founder mutations. Genotype-phenotype correlation allowed inference of the effect of each mutation on the function of the SMN1 protein and the role of the SMN2 copy number in modulating the SMA phenotype. In 14 of 23 SMA patients with two SMN1 copies, at least one intact SMN1 copy was sequenced, which excludes a 5q-SMA and suggests the existence of further gene(s) responsible for approximately 4%-5% of phenotypes indistinguishable from SMA. We determined the validity of the test, and we discuss its practical implications and limitations.  (+info)

Radiation-induced G1 arrest is not defective in fibroblasts from Li-Fraumeni families without TP53 mutations. (8/1398)

Radiation-induced G1 arrest was studied in four classes of early passage skin fibroblasts comprising 12 normals, 12 heterozygous (mut/wt) TP53 mutation-carriers, two homozygous (mut/-) TP53 mutation-carriers and 16 strains from nine Li-Fraumeni syndrome or Li-Fraumeni-like families in which no TP53 mutation has been found, despite sequencing of all exons, exon-intron boundaries, 3' and 5' untranslated regions and promoter regions. In an assay of p53 allelic expression in yeast, cDNAs from these non-mutation strains behaved as wild-type p53. Using two different assays, we found G1 arrest was reduced in heterozygous strains with mis-sense mutations and one truncation mutation, when compared to the range established for the normal cells. Heterozygous strains with mutations at splice sites behaved like normal cells, whilst homozygous (mut/-) strains showed either extremely reduced, or no, arrest. Strains from all nine non-mutation families gave responses within the normal range. Exceptions to the previously reported inverse correlation between G1 arrest and clonogenic radiation resistance were observed, indicating that these phenotypes are not strictly interdependent.  (+info)

Serum levels of aldosterone precursors were elevated in both patients before treatment. In particular, the serum ratios of 18-OHB to aldosterone were greatly elevated and declined to normal levels during mineralocorticoid replacement. The possibility of heterozygote detection using this ratio is suggested. We also confirm previous reports of a detrimental effect on linear growth rate after cessation of mineralocorticoid therapy despite maintenance of normal serum electrolytes. This effect is associated with biochemical evidence of chronic salt depletion. Based on our observations, we recommend that serum 18-OHB to aldosterone ratios be routinely measured for the diagnosis and management ...
Often when a couple starts to plan their family some of the things we tend to discuss are how many kids we would like to have, whether one parent will stay home with the kids, and where they will go to school.. Rarely, however, does a familys medical history come into question, unless a member of your family has been diagnosed with a rare disorder or genetic condition. But the truth is it is common for individuals to be carriers of 4-6 different recessive genetic conditions. If you and your partner are carriers of the same genetic condition, you have a 1 in 4 chance of having an affected child..

Germline mutations in the gene encoding for bone morphogenic receptor-2 (BMPR2) can cause pulmonary arterial hypertension (PAH). Molecular genetic diagnosis and counseling is currently available but not broadly implemented due to poor translation in direct clinical benefit.. We aim to investigate the influence of BMPR2 mutation on clinical outcome in PAH and selected parameters of long-term transthoracic echocardiography (TTE) and cardiopulmonary exercise test (CPET) follow-up in heritable PAH (HPAH) patient relatives.. BMPR2 mutation screening was performed in 124 sporadic or familial idiopathic PAH patients. Clinical, functional, hemodynamic parameters and outcome were compared in 23 BMPR2 mutation carriers and 101 noncarriers. Predictive screening was carried out in 53 HPAH relatives. TTE and CPET were performed repeatedly in 18 carriers and 15 noncarriers HPAH patient relatives, respectively.. As compared with noncarriers, BMPR2 mutation carriers were younger at diagnosis, had higher mean ...

Screening for genetic variants that predispose individuals or their offspring to disease may be performed at the general population level or may instead be targeted at the relatives of previously identified carriers. The latter strategy has come to be known as cascade genetic screening. Since the carrier risk of close relatives of known carriers is generally higher than the population risk, cascade screening is more efficient than population screening, in the sense that fewer individuals have to be genotyped per detected carrier. The efficacy of cascade screening, as measured by the overall proportion of carriers detected in a given population, is, however, lower than that of population-wide screening, and the respective inclusion rates vary according to the population frequency and mode of inheritance of the predisposing variants. For dominant mutations, we have developed equations that allow the inclusion rates of cascade screening to be calculated in an iterative fashion, depending upon ...

Cultured skin fibroblasts from patients with cystic fibrosis (CF) are more resistant to dexamethasone toxicity than are normal cells. We now report that, when fibroblasts cultured from obligate CF heterozygotes are exposed to dexamethasone, they have an intermediate survival compared to normal and homozygous CF cells. When dexamethasone survival was tested on cells from four patients undergoing amniocentesis, cells from a woman at risk of producing a child with CF showed significant dexamethasone resistance, similar to that of fibroblasts derived from lnown CF homozygotes; the other amniotic cell specimens showed dexamethasone sensitivity similar to that of normal skin fibroblasts. These data suggest that the dexamethasone resistance previously observed in skin fibroblasts may also be useful in the prenatal diagnosis of CF. ...

Cystic fibrosis is a multisystem disease that affects the lungs, pancreas, gastrointestinal tract and reproductive systems. Symptoms of cystic fibrosis can vary amongst individuals and most frequently include lower airway inflammation and chronic infections that can progress to end-stage lung disease. Pancreatic insufficiency with malabsorption is a complication that occurs in many individuals with CF. Most males with cystic fibrosis experience infertility. Individuals with cystic fibrosis have normal intelligence and the average median survival is currently 37 years. The most common cause of death is respiratory failure. Treatment of an individual with CF can include medication to improve digestion, monitored nutrition and lung therapy. Up to 15% of individuals with a diagnosis of cystic fibrosis can have a mild form with an average life expectancy of 56 years. Cystic Fibrosis is inherited in an autosomal recessive manner..

The frequency of different polymorphic variants of the multi-allelic locus DXS52 (St14) of the human X chromosome, adjacent to the factor VIII gene, was evaluated by means of PCR for the heterogeneous population of India. It was shown that the heterozygosity index of this polymorphism in the studied population of 282 unrelated subjects was much higher (88%) than reported elsewhere. Two new alleles (1750 bp and 1420 bp) were detected during this study. Out of 65 families studied using this polymorphism for carrier detection and antenatal diagnosis, 58 were informative with this polymorphism, thus indicating that this polymorphism can serve as an important marker in the carrier detection and prenatal diagnosis of haemophilia A families.

Genetic screening for cystic fibrosis carrier mutations (one copy of a mutated gene) is universally recommended for the reproductive-age population. Current professional guidelines call for screening a panel of 23 common mutations in CFTR; however, many laboratories screen for an expanded panel of mutations. In the May 2009 issue of The Journal of Molecular Diagnostics, three articles describe improvements in cystic fibrosis genetic screening. In one article, Pratt et al describes a project coordinated by the Centers for Disease Control and Preventions Genetic Testing Reference Material (GeT-RM) Program to develop a set of reference materials for the expanded cystic fibrosis panel of mutations. The public availability of these materials will help to ensure the accuracy of cystic fibrosis genetic testing. The reports by Schwartz et al and Hantash et al identify mutations that may lead to false screening results, either due to a large deletion in CFTR or because of mutations that interfere with ...
The molecular genetic diagnosis of inherited metabolic disorders is challenging. The diseases are rare, and most show locus heterogeneity. Hence, testing of the genes associated with IMDs is time consuming and often not easily available. We report a resequencing array that allows the simultaneous resequencing of up to 92 genes associated with IMDs. To validate the array, DNA samples from 51 patients with 52 different known variants (including point variants, small insertion, and deletions [indels]) in seven genes (C14ORF133, GAA, NPC1, NPC2, VPS33B, WFS1, and SLC19A2) were amplified by PCR and hybridized to the array. A further patient cohort with 48 different mutations in NPC1 were analyzed blind. Out of 76 point variants, 73 were identified using automated software analysis followed by manual review. Ten insertion and deletion variants were detected in the extra tiling using mutation specific probes, with 11 heterozygous deletions and 3 heterozygous insertions. In summary, we identified 96% (95%

A frequency bin method of carrier frequency acquisition uses a plurality of predetermined carrier frequency offset bins. A single bin is selected from among the plurality of bins. A local VCO is then adjusted to remove the carrier frequency offset associated with the single selected bin. Carrier frequency acquisition is then attempted using the adjusted VCO. If successful, the receiver enters its steady state operating mode. If unsuccessful, a new bin is selected and the VCO is again adjusted using the new carrier frequency offset associated with the newly selected bin. The process is repeated until successful communication is achieved in association with a properly adjusted VCO.

Rapidly determining the complex genetic basis of Hypertrophic cardiomyopathy (HCM) is vital to better understanding and optimally managing this common polygenetic cardiovascular disease. A rapid custom Ion-amplicon-resequencing assay, covering 30 commonly affected genes of HCM, was developed and validated in 120 unrelated patients with HCM to facilitate genetic diagnosis of this disease. With this HCM-specific panel and only 20 ng of input genomic DNA, physicians can, for the first time, go from blood samples to variants within a single day. On average, this approach gained 595628 mapped reads per sample, 95.51% reads on target (64.06 kb), 490-fold base coverage depth and 93.24% uniformity of base coverage in CDS regions of the 30 HCM genes. After validation, we detected underlying pathogenic variants in 87% (104 of 120) samples. Tested seven randomly selected HCM genes in eight samples by Sanger sequencing, the sensitivity and false-positive-rate of this HCM panel was 100% and 5%, respectively. This

original research this year for presentation at the annual meeting of the American Society for Reproductive Medicine (ASRM), held October 28 through November 1 in San Antonio, TX. Our study on genetic screening was accepted for poster presentation.. Carrier screening. expanded genetic carrier screening.. The subject of the study was the findings concerning PFC s experience since implementation of Expanded Genetic Carrier Screening, which began at our clinic in January of 2016. Since that time, we ve offered this type of screening to 1,332 patients (including partners) and egg donors using a panel from Natera called the Horizon Carrier Screen. We provided informed consent for expanded genetic carrier screening to all patients and recommended they have genetic counseling about their results.. Screening for men and women. The expanded Natera panel screens for 274 conditions in women and 254 conditions in men. The reason women are screened for more conditions is because they have two X chromosomes ...
Carrier screening, before or during pregnancy, can help determine the risk of having a child with a genetic disorder. The American College of Obstetricians and Gynecologists (ACOG) recommends that all women be offered pre/post-conception carrier screening for cystic fibrosis and spinal muscular atrophy. Additionally, ACOG supports carrier screening for other disorders based on the patients medical and family history. CTGT offers several options for carrier screening, including single disorder tests and multiple disorder panels. Full gene sequencing and large deletion/duplication analysis is performed for these carrier tests to obtain the highest sensitivity regardless of ethnic background. Spinal muscular atrophy testing includes assessment of SMN1/2 copy number and silent carrier risk. Fragile X testing include determination of the number of CGG repeats in the 5UTR of FMR1.. ...

Conclusions The PI-MZ rare (2%) SNP effect is nearly four times greater than the top common height SNP in HMGA2. However, height only partially attenuates the SERPINA1-FEV1 or FVC association (around 50%) and vice versa. Height SNP variants have recently been shown to be positively selected collectively in North versus South Europeans, while the Z allele high frequency is localised to North Europe. Although PI-ZZ is clinically disadvantageous to lung function, PI-MZ increases both height and respiratory function; potentially a balanced polymorphism. Partial blockade of PI could conceivably form part of a future poly-therapeutic approach in very short children. The notion that elastase inhibition should benefit patients with chronic obstructive pulmonary disease may also merit re-evaluation. PI is already a therapeutic target: our findings invite a reconsideration of the optimum level in respiratory care and novel pathway potential for development of agents for the management of growth ...
Cystic fibrosis (CF) is an inherited condition that mainly affects the lungs, pancreas and sweat glands. Lab tests may be used to screen for and help diagnose cystic fibrosis and to determine if someone is a genetic carrier of CF.

Duchenne/Becker muscular dystrophy (DMD/BMD) is a genetic disorder that develops in boys. It is caused by a mutation in the gene for dystrophin, a protein that is important for maintaining normal muscle structure and function. Loss of dystrophin causes muscle fragility that leads to weakness and loss of walking ability during childhood and teenage years. A specific type of mutation, called a nonsense (premature stop codon) mutation is the cause of DMD/BMD in approximately 10-15% of boys with the disease. Ataluren (PTC124) is an orally delivered, investigational drug that has the potential to overcome the effects of the nonsense mutation. This study is a Phase 2b extension trial that will evaluate the long-term safety of ataluren (PTC124) in boys with nonsense mutation DMD/BMD, as determined by adverse events and laboratory abnormalities. The study will also assess changes in walking, muscle function, and other important clinical and laboratory measures ...

article{6540f780-e849-4367-a13e-127a460cab4a, abstract = {Haemophilia B, an X-linked recessive bleeding disorder characterized by lack or deficiency of factor IX, has been shown to be caused by any of a variety of DNA abnormalities (partial or total deletions, nonsense or missense mutations). Since in most countries carrier detection is based on factor IX coagulant activity (FIX:C) assay, this study was designed to determine whether carriers FIX:C values are dependent on the severity of haemophilia (mild, moderate or severe) or on the genetic anomaly in the family. FIX:C concentrations were studied in 28 obligate carriers, 39 women known to carry the mutation and 33 verified noncarriers subgrouped by severity of disorder or genetic anomaly. No significant subgroup differences in FIX:C values were found, thus suggesting the level of FIX:C concentrations in carriers to be unaffected by the severity of haemophilia, or by its expression (i.e. deficient or dysfunctional factor IX). The specificity ...
The cystic fibrosis (CF) carrier screen is a blood test taken by parents to see if they carry the abnormal genes that cause CF, in order to determine the risk of having a child with CF.
The hyperphenylalaninemias are disorders of phenylalanine hydroxylation. The disease results from the absence of the hepatic phehylalaniene hydrosylase (PAH) and causes mental retardation. The clinical manifestations and consequences of hyperphenylalaninaemia are due to abnormal accumulation of normal metabolites, thus resulting in mental retardation. This can be rectified by early diagnosis of the disease and the dietary treatment there-of. It is unfortunate that in most instances the diagnosis is only made after permanent and irreversible brain damage has occurred. This can be rectified if PKU carrier diagnosis is applied to identify those high risk families. ,br,,br, Metabolite analyses led to the identification of hyperphehylalaninaemia patients. This phase was part of the normal screening program for the identification of amino-acidpathies of severely ill infants referred to ,the Department of Biochemistry at the Potchefstroom University for Christian Higher Education (PU for CHE). ...

Cystic fibrosis (CF) is a serious inherited disease that affects the lungs and makes it hard to digest food.. In the United States, about 1 out of every 3,500 babies is born with CF. It is most common among people who are white.. CF carrier screening tests identify men and women who carry an abnormal gene for CF. This means that their babies might inherit the disease.. To inherit cystic fibrosis, a child must receive two abnormal CF genes, one from each parent. A CF carrier is a healthy person who has one normal CF gene and one abnormal CF gene.. Health care providers routinely offer a carrier screening test to men and women who have a family history of CF. Many providers also offer the test to all couples who are planning pregnancy or are pregnant. Couples must decide for themselves if testing is right for them.. To take the test, men and women provide a blood or saliva sample.. An improved carrier screening test was recently announced. It can detect 39 genetic mutations that can lead to ...
The modified messenger RNA contains the coding sequence for the active component of telomerase, called TERT. Telomerase is the enzyme that rebuilds telomeres and stem cells, including those that give rise eggs and sperm, express the enzyme at a much higher rate than other kinds of cells. Essentially, the RNA is a kind of genetic carrier pigeon in that it carries instructions from the DNAs genes to the cells protein-making areas. Interestingly, in previous work Dr Blau found that the muscle stem cells of boys with Duchenne muscular dystrophy had far shorter telomeres than those not suffering from the disease ...
