The c.1346C>T (p.A449V) alteration is located in exon 3 (coding exon 2) of the IRGQ gene. This alteration results from a C to T substitution at nucleotide position 1346, causing the alanine (A) at amino acid position 449 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
