Genes affected

NSMAF (HGNC:8017): (neutral sphingomyelinase activation associated factor) This gene encodes a WD-repeat protein that binds the cytoplasmic sphingomyelinase activation domain of the 55kD tumor necrosis factor receptor. This protein is required for TNF-mediated activation of neutral sphingomyelinase and may play a role in regulating TNF-induced cellular responses such as inflammation. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Jan 2009]

The c.1154G>A (p.G385E) alteration is located in exon 14 (coding exon 14) of the NSMAF gene. This alteration results from a G to A substitution at nucleotide position 1154, causing the glycine (G) at amino acid position 385 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
