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]

The c.1669A>G (p.R557G) alteration is located in exon 1 (coding exon 1) of the FEM1A gene. This alteration results from a A to G substitution at nucleotide position 1669, causing the arginine (R) at amino acid position 557 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
