The c.653A>G (p.Q218R) alteration is located in exon 3 (coding exon 2) of the ZDHHC23 gene. This alteration results from a A to G substitution at nucleotide position 653, causing the glutamine (Q) at amino acid position 218 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
