The c.585G>A (p.M195I) alteration is located in exon 6 (coding exon 4) of the ACY3 gene. This alteration results from a G to A substitution at nucleotide position 585, causing the methionine (M) at amino acid position 195 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
