The c.1637A>G (p.H546R) alteration is located in exon 3 (coding exon 2) of the IRGQ gene. This alteration results from a A to G substitution at nucleotide position 1637, causing the histidine (H) at amino acid position 546 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
