The c.544G>T (p.D182Y) alteration is located in exon 6 (coding exon 5) of the PHRF1 gene. This alteration results from a G to T substitution at nucleotide position 544, causing the aspartic acid (D) at amino acid position 182 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
