Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001007561.3(IRGQ):c.1176G>C(p.Glu392Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000372 in 1,610,812 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E392Q) has been classified as Uncertain significance.

Collection Method:clinical testing

The c.1176G>C (p.E392D) alteration is located in exon 3 (coding exon 2) of the IRGQ gene. This alteration results from a G to C substitution at nucleotide position 1176, causing the glutamic acid (E) at amino acid position 392 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
