Genes affected

NMT2 (HGNC:7858): (N-myristoyltransferase 2) This gene encodes one of two N-myristoyltransferase proteins. N-terminal myristoylation is a lipid modification that is involved in regulating the function and localization of signaling proteins. The encoded protein catalyzes the addition of a myristoyl group to the N-terminal glycine residue of many signaling proteins, including the human immunodeficiency virus type 1 (HIV-1) proteins, Gag and Nef. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

The c.1487T>C (p.V496A) alteration is located in exon 12 (coding exon 12) of the NMT2 gene. This alteration results from a T to C substitution at nucleotide position 1487, causing the valine (V) at amino acid position 496 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
