Genes affected
ETNK1 (HGNC:24649): (ethanolamine kinase 1) This gene encodes an ethanolamine kinase, which functions in the first committed step of the phosphatidylethanolamine synthesis pathway. This cytosolic enzyme is specific for ethanolamine and exhibits negligible kinase activity on choline. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2024The c.360G>C (p.E120D) alteration is located in exon 1 (coding exon 1) of the ETNK1 gene. This alteration results from a G to C substitution at nucleotide position 360, causing the glutamic acid (E) at amino acid position 120 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
