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 creates a premature translational stop signal (p.Gln116*) in the HOGA1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in HOGA1 are known to be pathogenic (PMID: 22391140, 22781098). This variant is present in population databases (no rsID available, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with primary hyperoxaluria (PMID: 22781098). ClinVar contains an entry for this variant (Variation ID: 204271). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this premature translational stop signal affects HOGA1 function (PMID: 22781098). For these reasons, this variant has been classified as Pathogenic.
