The c.2432T>A (p.F811Y) alteration is located in exon 9 (coding exon 8) of the PCNX4 gene. This alteration results from a T to A substitution at nucleotide position 2432, causing the phenylalanine (F) at amino acid position 811 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
