Genes affected

CERS2 (HGNC:14076): (ceramide synthase 2) This gene encodes a protein that has sequence similarity to yeast longevity assurance gene 1. Mutation or overexpression of the related gene in yeast has been shown to alter yeast lifespan. The human protein may play a role in the regulation of cell growth. Alternatively spliced transcript variants encoding the same protein have been described. [provided by RefSeq, Jul 2008]

The c.1088G>A (p.R363Q) alteration is located in exon 11 (coding exon 10) of the CERS2 gene. This alteration results from a G to A substitution at nucleotide position 1088, causing the arginine (R) at amino acid position 363 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
