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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.615G>C (p.Q205H) alteration is located in exon 6 (coding exon 6) of the CERS5 gene. This alteration results from a G to C substitution at nucleotide position 615, causing the glutamine (Q) at amino acid position 205 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
