The c.838A>G (p.M280V) alteration is located in exon 6 (coding exon 6) of the VAT1L gene. This alteration results from a A to G substitution at nucleotide position 838, causing the methionine (M) at amino acid position 280 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
