The c.1886G>A (p.R629H) alteration is located in exon 20 (coding exon 19) of the GPCPD1 gene. This alteration results from a G to A substitution at nucleotide position 1886, causing the arginine (R) at amino acid position 629 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
