We have identified a novel missense mutation, an A-T transition at codon 684 in exon 17, changing an encoded asparagine to a tyrosine (Asn684Tyr) in a Spanish patient with typical McArdle's disease. The patient was a compound heterozygote, with a previously-described mutation (Gly204Ser) on the other allele. This report expands the molecular genetic(More)
We identified a new mutation in the myophosphorylase gene in a Japanese family with McArdle's disease. This point mutation results in the replacement of a tryptophan at amino acid position 361 with a stop codon, the third nonsense mutation in this disorder. Our findings further expand the already wide spectrum of genetic lesions associated with McArdle's(More)
We analyzed leukocyte DNA of 19 patients from 12 Spanish families with McArdle's disease (myophosphorylase deficiency). In 15 patients, the enzyme defect was documented histochemically in muscle, and in four the diagnosis was based on clinical and laboratory data. Three patients were homozygous and six were heterozygous for the nonsense mutation at codon 49(More)
Mutations of the cystic fibrosis transmembrane regulator (CFTR) gene and polymorphisms, such as the (TG)m and Tn polymorphic loci in intron 8 at the splice acceptor site of exon 9, can cause male infertility. The aim of this study was to investigate the frequency of the most prevalent cystic-fibrosis-causing mutations, the IVS8-Tn alleles and IVS8-TG12(More)
The FSHB gene -211G/T polymorphism has been reported to modulate gene expression and to cause inter-individual differences in FSH serum levels in men. This study was undertaken to assess the functional relevance of this polymorphism on gonadotropin and total testosterone serum levels and sperm parameters in men from Eastern Sicily (Italy). To accomplish(More)
The ubiquitin-proteasome is an ubiquitous system mainly devoted to protein degradation. The presence of ubiquitinated proteins in male gametes suggests a role for this system also in reproduction. Available evidence indicate that ubiquitin in spermatozoa may have a role in semen quality control, as ubiquitinated defective spermatozoa in the epididymis are(More)
The functional role of the FSHR promoter −29G/A polymorphism (rs1394205) in men is not clear. Some studies failed to find a relationship between the FSHR −29G/A and follicle-stimulating hormone (FSH) levels and did not associate the SNP with male infertility. Only one study showed that the FSHR −29 SNP modulates serum FSH levels in Baltic young male cohort.(More)
We have studied two large unrelated Finnish families with myophosphorylase deficiency (McArdle's disease). In one, we identified a new nonsense mutation at codon 540 in exon 14 of the myophosphorylase gene, changing an encoded glutamic acid to a stop codon (E540X). The second family carried a splice-junction mutation at the 5' splice site of intron 14(More)
