The c.379G>A (p.A127T) alteration is located in exon 4 (coding exon 3) of the PHRF1 gene. This alteration results from a G to A substitution at nucleotide position 379, causing the alanine (A) at amino acid position 127 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
