Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_014691.3(AQR):c.4280G>A(p.Arg1427His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000743 in 1,614,078 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/20 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. R1427C) has been classified as Uncertain significance.

The c.4280G>A (p.R1427H) alteration is located in exon 35 (coding exon 35) of the AQR gene. This alteration results from a G to A substitution at nucleotide position 4280, causing the arginine (R) at amino acid position 1427 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
