Genes affected

OOEP (HGNC:21382): (oocyte expressed protein) Predicted to enable RNA binding activity. Predicted to be involved in several processes, including cytoskeleton organization; positive regulation of double-strand break repair via homologous recombination; and positive regulation of meiotic nuclear division. Predicted to act upstream of or within several processes, including embryo implantation; in utero embryonic development; and protein phosphorylation. Located in cytoplasm and nucleus. Part of subcortical maternal complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.08728638).
• BP6: Variant 6-73369251-T-C is Benign according to our data. Variant chr6-73369251-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 3204342.Status of the report is criteria_provided_single_submitter, 1 stars.

Ambry Genetics

Nov 13, 2023

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
