The c.253A>G (p.M85V) alteration is located in exon 3 (coding exon 3) of the SMYD2 gene. This alteration results from a A to G substitution at nucleotide position 253, causing the methionine (M) at amino acid position 85 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
