The c.784A>T (p.M262L) alteration is located in exon 8 (coding exon 8) of the ELOVL2 gene. This alteration results from a A to T substitution at nucleotide position 784, causing the methionine (M) at amino acid position 262 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
