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 q11.222q11.23 (containing AZFb and AZFc) encompassing 20 OMIM genes, including HSFY1, PRY, and DAZ1, which can cause oligospermia and infertility in men (Figure 3C). Here, ENSG00000235059 is linked to Infertility.
