Genes affected

WEE2 (HGNC:19684): (WEE2 oocyte meiosis inhibiting kinase) Predicted to enable protein tyrosine kinase activity. Predicted to be involved in several processes, including female pronucleus assembly; negative regulation of oocyte maturation; and regulation of meiosis I. Located in cytosol; nucleoplasm; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

WEE2-AS1 (HGNC:48669): (WEE2 antisense RNA 1)
