The c.2204G>A (p.R735Q) alteration is located in exon 22 (coding exon 22) of the ACAP3 gene. This alteration results from a G to A substitution at nucleotide position 2204, causing the arginine (R) at amino acid position 735 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
