Aug 05, 2024

The c.1403G>A (p.S468N) 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 1403, causing the serine (S) at amino acid position 468 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
