Study Description

Purpose: The purpose of this study was to identify mutations that cause non-syndromic male infertility using whole exome sequencing of family cases.Methods: We recruited a consanguineous Turkish family comprising nine siblings with male triplets; two of the triplets were infertile as well as one younger infertile brother. Whole exome sequencing (WES) performed on two azoospermic brothers, identified a mutation in the MAGEB4 gene which was confirmed via Sanger sequencing and then screened for on control groups and unrelated infertile subjects. The effect of the mutation on mRNA and protein levels were tested after in vitro cell transfection. Structural features of MAGEB4 were predicted throughout the conserved MAGE domain.Results: The novel single base substitution (c.1041A>T) in the X-linked MAGEB4 gene was identified as a no-stop mutation. The mutation is predicted to add 24 amino acids to the C-terminus of MAGEB4. Our functional studies were unable to detect any effect either on mRNA stability, intracellular localization of the protein or the ability to homo / heterodimerize ... (Show More)
