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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.790G>A (p.V264M) alteration is located in exon 5 (coding exon 5) of the ETNK2 gene. This alteration results from a G to A substitution at nucleotide position 790, causing the valine (V) at amino acid position 264 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
