Aug 05, 2024

The c.2024C>A (p.T675N) alteration is located in exon 3 (coding exon 3) of the PTCHD4 gene. This alteration results from a C to A substitution at nucleotide position 2024, causing the threonine (T) at amino acid position 675 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
