The c.469T>C (p.Y157H) alteration is located in exon 5 (coding exon 3) of the ACY3 gene. This alteration results from a T to C substitution at nucleotide position 469, causing the tyrosine (Y) at amino acid position 157 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
