The c.664C>A (p.H222N) alteration is located in exon 4 (coding exon 3) of the PID1 gene. This alteration results from a C to A substitution at nucleotide position 664, causing the histidine (H) at amino acid position 222 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
