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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.1012G>T (p.A338S) alteration is located in exon 9 (coding exon 9) of the CERS5 gene. This alteration results from a G to T substitution at nucleotide position 1012, causing the alanine (A) at amino acid position 338 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
