Genes affected

FEM1C (HGNC:16933): (fem-1 homolog C) Enables ubiquitin ligase-substrate adaptor activity. Involved in ubiquitin-dependent protein catabolic process via the C-end degron rule pathway. Located in cytosol and nucleoplasm. Part of Cul2-RING ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, FEM1C
• BP4: Computational evidence support a benign effect (MetaRNN=0.038749963).

The c.189A>T (p.Q63H) alteration is located in exon 2 (coding exon 1) of the FEM1C gene. This alteration results from a A to T substitution at nucleotide position 189, causing the glutamine (Q) at amino acid position 63 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
