The c.1450A>G (p.T484A) alteration is located in exon 12 (coding exon 11) of the PHF20L1 gene. This alteration results from a A to G substitution at nucleotide position 1450, causing the threonine (T) at amino acid position 484 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
