Genes affected

NOM1 (HGNC:13244): (nucleolar protein with MIF4G domain 1) Proteins that contain MIF4G (middle of eIF4G (MIM 600495)) and/or MA3 domains, such as NOM1, function in protein translation. These domains include binding sites for members of the EIF4A family of ATP-dependent DEAD box RNA helicases (see EIF4A1; MIM 602641) (Simmons et al., 2005 [PubMed 15715967]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Oct 25, 2024

The c.5C>A (p.A2E) alteration is located in exon 1 (coding exon 1) of the NOM1 gene. This alteration results from a C to A substitution at nucleotide position 5, causing the alanine (A) at amino acid position 2 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
