Ambry Genetics

Feb 23, 2023

The c.1195G>T (p.G399C) alteration is located in exon 3 (coding exon 2) of the IRGQ gene. This alteration results from a G to T substitution at nucleotide position 1195, causing the glycine (G) at amino acid position 399 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
