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]

The c.930C>G (p.H310Q) alteration is located in exon 6 (coding exon 6) of the ETNK2 gene. This alteration results from a C to G substitution at nucleotide position 930, causing the histidine (H) at amino acid position 310 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
