Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM5PP3_ModeratePP5_Very_Strong
The NM_138413.4(HOGA1):c.860G>A(p.Gly287Glu) variant causes a missense change. The variant allele was found at a frequency of 0.0000112 in 1,614,222 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G287V) has been classified as Pathogenic.

This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 287 of the HOGA1 protein (p.Gly287Glu). This variant is present in population databases (rs138207257, gnomAD 0.02%). This missense change has been observed in individual(s) with primary hyperoxaluria type 3 (PMID: 29705963). ClinVar contains an entry for this variant (Variation ID: 2149465). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt HOGA1 protein function with a positive predictive value of 95%. This variant disrupts the p.Gly287 amino acid residue in HOGA1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 20797690, 21896830, 22391140, 27561601). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
