Genes affected

FEM1A (HGNC:16934): (fem-1 homolog A) Enables EP4 subtype prostaglandin E2 receptor binding activity and ubiquitin ligase-substrate adaptor activity. Involved in negative regulation of inflammatory response and ubiquitin-dependent protein catabolic process via the C-end degron rule pathway. Part of Cul2-RING ubiquitin ligase complex. Is active in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Feb 22, 2023

The c.878G>C (p.S293T) alteration is located in exon 1 (coding exon 1) of the FEM1A gene. This alteration results from a G to C substitution at nucleotide position 878, causing the serine (S) at amino acid position 293 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
