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]

Dec 31, 2023

The c.671T>C (p.V224A) alteration is located in exon 4 (coding exon 4) of the ETNK2 gene. This alteration results from a T to C substitution at nucleotide position 671, causing the valine (V) at amino acid position 224 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
