Nov 27, 2024

The c.265A>G (p.T89A) alteration is located in exon 4 (coding exon 3) of the PHRF1 gene. This alteration results from a A to G substitution at nucleotide position 265, causing the threonine (T) at amino acid position 89 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
