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]

The c.1027G>T (p.D343Y) alteration is located in exon 9 (coding exon 9) of the CERK gene. This alteration results from a G to T substitution at nucleotide position 1027, causing the aspartic acid (D) at amino acid position 343 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
