The c.815A>C (p.Q272P) alteration is located in exon 7 (coding exon 7) of the GRTP1 gene. This alteration results from a A to C substitution at nucleotide position 815, causing the glutamine (Q) at amino acid position 272 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
