Collection Method:clinical testing

The c.1286C>A (p.P429Q) alteration is located in exon 3 (coding exon 2) of the IRGQ gene. This alteration results from a C to A substitution at nucleotide position 1286, causing the proline (P) at amino acid position 429 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
