The c.326C>T (p.P109L) alteration is located in exon 4 (coding exon 3) of the PHF19 gene. This alteration results from a C to T substitution at nucleotide position 326, causing the proline (P) at amino acid position 109 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
