The c.1283C>T (p.P428L) 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 1283, causing the proline (P) at amino acid position 428 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
