For example, targeted sequencing of candidate genes in patients experiencing recurrent IVF failure identified loss‐of‐function variants in a primate‐specific tubulin b class VIII (TUBB8),89, 90, 91 PAT1 homolog 2 (PATL2),92, 93, 94, 95, 96, 97 and WEE2 oocyte meiosis inhibiting kinase (WEE2)98, 99, 100, 101, 102 that may predispose women to a higher incidence of oocyte and embryonic aneuploidy at younger‐than‐average ages. The gene discussed is WEE2; the disease is aneuploidy.
