The c.409A>G (p.K137E) alteration is located in exon 5 (coding exon 5) of the ELOVL2 gene. This alteration results from a A to G substitution at nucleotide position 409, causing the lysine (K) at amino acid position 137 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
