The c.1345A>T (p.T449S) alteration is located in exon 14 (coding exon 13) of the PHF19 gene. This alteration results from a A to T substitution at nucleotide position 1345, causing the threonine (T) at amino acid position 449 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
