Novel WEE2 homozygous mutations c.1346C & gt;T and c.949A & gt;T identified in primary infertile women due to unexplained fertilization failure

Clin Genet. 2023 Sep 29. doi: 10.1111/cge.14429. Online ahead of print.ABSTRACTThe occurrence of unexplained fertilization failure can have profound psychological and financial consequences for couples struggling with infertility, and its pathogenesis remains unclear. Increasing evidence highlights genetic basis of unexplained fertilization failure occurrence. Here, we identified one novel homozygous nonsense mutation (c.949A>T), one novel homozygous missense mutation (c.1346C>T), and three reported homozygous mutations (c.585G>C, c.1006_1007insTA, c.1221G>A) in six unrelated probands, showing similar manifestations of unexplained fertilization failure. This finding expands the spectrum of WEE2 mutations, highlighting the critical role of WEE2 in fertilization process, and provides a basis for the prognostic value of testing for WEE2 mutations in primary infertile couples with unexplained fertilization failure.PMID:37772619 | DOI:10.1111/cge.14429
