Genes affected

ETNK2 (HGNC:25575): (ethanolamine kinase 2) The protein encoded by this gene is a member of choline/ethanolamine kinase family which catalyzes the first step of phosphatidylethanolamine (PtdEtn) biosynthesis via the cytidine diphosphate (CDP) ethanolamine pathway. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

Ambry Genetics

Jul 26, 2022

The c.118C>G (p.R40G) alteration is located in exon 1 (coding exon 1) of the ETNK2 gene. This alteration results from a C to G substitution at nucleotide position 118, causing the arginine (R) at amino acid position 40 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
