Genes affected

IGBP1C (HGNC:43611): (IGBP1 family member C) Predicted to enable protein phosphatase 2A binding activity. Predicted to be involved in regulation of dephosphorylation. Predicted to be active in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

TEX14 (HGNC:11737): (testis expressed 14, intercellular bridge forming factor) The protein encoded by this gene is necessary for intercellular bridges in germ cells, which are required for spermatogenesis. Three transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2011]

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 (BayesDel_noAF=-0.86).
