The c.509G>A (p.R170Q) alteration is located in exon 5 (coding exon 5) of the PSMG1 gene. This alteration results from a G to A substitution at nucleotide position 509, causing the arginine (R) at amino acid position 170 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
