Genes affected

CERK (HGNC:19256): (ceramide kinase) CERK converts ceramide to ceramide 1-phosphate (C1P), a sphingolipid metabolite. Both CERK and C1P have been implicated in various cellular processes, including proliferation, apoptosis, phagocytosis, and inflammation (Kim et al., 2006 [PubMed 16488390]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Feb 10, 2022

The c.1226C>T (p.P409L) alteration is located in exon 11 (coding exon 11) of the CERK gene. This alteration results from a C to T substitution at nucleotide position 1226, causing the proline (P) at amino acid position 409 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
