Variable phenotypes are associated with PMP22 missense mutations.
Charcot-Marie-Tooth disease (CMT) is the commonest hereditary neuropathy encompassing a large group of clinically and genetically heterogeneous disorders. The commonest form of CMT, CMT1A, is usually caused by a 1.4 megabase duplication of chromosome 17 containing the PMP22 gene. Mutations of PMP22 are a less common cause of CMT. We describe clinical, electrophysiological and molecular findings...
متن کاملChloride channels are involved in sperm motility and are downregulated in spermatozoa from patients with asthenozoospermia
Human spermatozoa encounter an osmotic decrease from 330 to 290 mOsm l-1 when passing through the female reproductive tract. We aimed to evaluate the role of chloride channels in volume regulation and sperm motility from patients with asthenozoospermia. Spermatozoa were purified using Percoll density gradients. Sperm volume was measured as the forward scatter signal using flow cytometry. Sperm ...
متن کاملScreening of two closed mutations in CFTR gene of Iranian infertile men with non-obstructive azoospermia
Background The genetic association between cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations and male infertility due to congenital bilateral absence of vas deferens (CBAVD) is well established. Mutant CFTR, however may also be involved in the etiology of male infertility in non-CBAVD cases. The present study was conducted to estimate the frequency of ΔI507 and ΔF508 CFT...
متن کاملCFTR Mutations in Congenital Absence of Vas Deferens
A qualitative diagnosis of infertility requires attention to female and male physical abnormalities, endocrine anomalies and genetic conditions that interfere with reproduction. Many genes are likely to be involved in the complex process of reproduction. Cystic fibrosis (CF) incidence varies in different White people populations (a higher incidence of CF is observed in northern–western European...
متن کاملa novel missense mutation, e1623g, in the human factor viii gene associated with moderate haemophilia a
introduction: haemophilia a is the most common inherited x-linked recessive bleeding disorder. the severity of the resultant bleeding diathesis depends on the fviii levels associated with the mutation. analysis of carrier state can be made indirectly by dna linkage analysis or directly by identifying the mutation that leads to the disease. the aim of this study was to identification of the caus...
