The c.326T>C (p.F109S) alteration is located in exon 3 (coding exon 3) of the PXMP4 gene. This alteration results from a T to C substitution at nucleotide position 326, causing the phenylalanine (F) at amino acid position 109 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
