Background\/Objectives: Although biallelic pathogenic variants in different DNAH gene family members have been associated with infertility, the role of DNAH12 in this disorder is still incompletely understood. To date, few patients have been shown to have infertility due to biallelic variants in this gene. Here, we report two more unrelated patients with infertility who carry homozygous variants in DNAH12. <\/p>\n\n\n\n
Methods: This study included two male patients with primary infertility and oligoasthenoteratozoospermia (OAT). Patient 1 was a 32-year-old with 1.5 years of infertility and no chronic illnesses or prior assisted reproductive technologies (ARTs). Patient 2 was a 49-year-old with 24 years of infertility, a history of varicocelectomy, and the occasional use of PRN analgesics for bone pain. Using genome sequencing, we identified two homozygous variants: c.3757C>A, p. Pro1253Thr, and c.11086-1G>A, p.?, in patients 1 and 2, respectively. <\/p>\n\n\n\n
Results: Our findings add supportive evidence that DNAH12 is a gene implicated in rare cases of male infertility. The identification of these homozygous variants in two additional patients supports the association between DNAH12 variants and reproductive dysfunction. <\/p>\n\n\n\n
Conclusions: This study highlights the need for further research on the role of DNAH12, including functional studies to clarify the mechanisms contributing to infertility.<\/p>\n\n\n\n
