STRC and male infertility: The most recurrent pathogenic CNV observed in our cohort and present in heterozygosity in 38 individuals (AF = 0.91%) was a microdeletion of approximately 57.9 kb (coordinates: chr15:43600849_43658715) involving exons 1 through 26 (out of a total of 29 exons) of the STRC gene, associated with the AR form of NSHL, along with the CATSPER2 gene (not associated with any Mendelian disorder in the OMIM database; however, biallelic deletions concomitantly involving STRC and CATSPER2 are associated with HL and male infertility, OMIM:611102).
