The c.2470A>G (p.K824E) alteration is located in exon 3 (coding exon 3) of the PTCHD4 gene. This alteration results from a A to G substitution at nucleotide position 2470, causing the lysine (K) at amino acid position 824 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
