So it is possible that a defective autosomal DAZL gene may be responsible for spermatogenic defects in some cases and that the genetic defect is inherited in an autosomal recessive fashion.[6] A mutation at nucleotide A386G in exon 3 of the DAZL gene in some infertile patients in a Taiwanese population was observed by Teng et al.[7] There are, however, no other reported instances of a positive association of DAZL gene mutations with infertility in men. Here, DAZL is linked to Infertility.
