Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.1322G>A (p.G441E) 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 1322, causing the glycine (G) at amino acid position 441 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
