The c.764G>A (p.R255H) alteration is located in exon 8 (coding exon 8) of the DAPP1 gene. This alteration results from a G to A substitution at nucleotide position 764, causing the arginine (R) at amino acid position 255 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
