Genes affected

CERS5 (HGNC:23749): (ceramide synthase 5) This gene encodes a protein that belongs to the TLC (TRAM, LAG1 and CLN8 homology domains) family of proteins. The encoded protein functions in the synthesis of ceramide, a lipid molecule that is involved in a several cellular signaling pathways. Alternate splicing results in multiple transcript variants.

The c.235G>A (p.E79K) alteration is located in exon 2 (coding exon 2) of the CERS5 gene. This alteration results from a G to A substitution at nucleotide position 235, causing the glutamic acid (E) at amino acid position 79 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
