The c.76A>G (p.M26V) alteration is located in exon 2 (coding exon 1) of the KATNAL1 gene. This alteration results from a A to G substitution at nucleotide position 76, causing the methionine (M) at amino acid position 26 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
