The c.1420G>A (p.A474T) alteration is located in exon 3 (coding exon 2) of the IRGQ gene. This alteration results from a G to A substitution at nucleotide position 1420, causing the alanine (A) at amino acid position 474 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
