The c.686C>A (p.P229H) alteration is located in exon 1 (coding exon 1) of the MRGPRG gene. This alteration results from a C to A substitution at nucleotide position 686, causing the proline (P) at amino acid position 229 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
