The c.39C>A (p.N13K) alteration is located in exon 3 (coding exon 1) of the PHYHIP gene. This alteration results from a C to A substitution at nucleotide position 39, causing the asparagine (N) at amino acid position 13 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
