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.1342G>A (p.D448N) alteration is located in exon 1 (coding exon 1) of the FEM1A gene. This alteration results from a G to A substitution at nucleotide position 1342, causing the aspartic acid (D) at amino acid position 448 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
