Subsequent SNP array analysis of amniocytes revealed a 2.3 Mb genomic gain in Yq11.221q11.222 (encompassing one OMIM gene) and a 6.1 Mb genomic loss in Yq11.222q11.23, spanning 18 OMIM genes and encompassing HSFY1, PRY,DAZ1, AZFb, and AZFc, which are associated with azoospermia, oligospermia, and infertility (Figure 3C). Here, DAZ1 is linked to Azoospermia.
