Genes affected

RPP38 (HGNC:30329): (ribonuclease P/MRP subunit p38) Enables ribonuclease P RNA binding activity. Contributes to ribonuclease P activity. Involved in tRNA 5'-leader removal. Located in fibrillar center. Part of multimeric ribonuclease P complex. [provided by Alliance of Genome Resources, Apr 2022]

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]

ACMG classification
