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]

Dec 27, 2023

The c.1256A>G (p.Y419C) alteration is located in exon 15 (coding exon 15) of the NSMAF gene. This alteration results from a A to G substitution at nucleotide position 1256, causing the tyrosine (Y) at amino acid position 419 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
