Genes affected

HOGA1 (HGNC:25155): (4-hydroxy-2-oxoglutarate aldolase 1) The authors of PMID:20797690 cloned this gene while searching for genes in a region of chromosome 10 linked to primary hyperoxalurea type III. They noted that even though the encoded protein has been described as a mitochondrial dihydrodipicolinate synthase-like enzyme, it shares little homology with E. coli dihydrodipicolinate synthase (Dhdps), particularly in the putative substrate-binding region. Moreover, neither lysine biosynthesis nor sialic acid metabolism, for which Dhdps is responsible, occurs in vertebrate mitochondria. They propose that this gene encodes mitochondrial 4-hydroxyl-2-oxoglutarate aldolase (EC 4.1.3.16), which catalyzes the final step in the metabolic pathway of hydroxyproline, releasing glyoxylate and pyruvate. This gene is predominantly expressed in the liver and kidney, and mutations in this gene are found in patients with primary hyperoxalurea type III. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Nov 2010]

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. -
