The c.461A>G (p.Q154R) alteration is located in exon 8 (coding exon 5) of the PCGF3 gene. This alteration results from a A to G substitution at nucleotide position 461, causing the glutamine (Q) at amino acid position 154 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
