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.

Ambry Genetics

Nov 17, 2022

The c.792G>T (p.K264N) alteration is located in exon 8 (coding exon 8) of the CERS5 gene. This alteration results from a G to T substitution at nucleotide position 792, causing the lysine (K) at amino acid position 264 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
