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 Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, FEM1C
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.763

The c.440G>A (p.R147Q) alteration is located in exon 2 (coding exon 1) of the FEM1C gene. This alteration results from a G to A substitution at nucleotide position 440, causing the arginine (R) at amino acid position 147 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
