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.1537G>A (p.V513I) alteration is located in exon 12 (coding exon 12) of the CERK gene. This alteration results from a G to A substitution at nucleotide position 1537, causing the valine (V) at amino acid position 513 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
