The c.2465G>C (p.R822P) alteration is located in exon 3 (coding exon 3) of the PTCHD4 gene. This alteration results from a G to C substitution at nucleotide position 2465, causing the arginine (R) at amino acid position 822 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
