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)

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 7-141727383-G-GA is Pathogenic according to our data. Variant chr7-141727383-G-GA is described in ClinVar as [Pathogenic]. Clinvar id is 545470.Status of the report is no_assertion_criteria_provided, 0 stars.
