Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PS3 PM1 PM2 PM5 PP2 PP3 PP5_Very_Strong

The NM_138413.4(HOGA1):​c.860G>T​(p.Gly287Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000595 in 1,614,104 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 Pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000915488: Riedel et al. (2012) found that protein products of the p.Gly287Val variant were unstable, had a tendency to aggregate, and retained no measurable activity, as compared to the wild type protein. PMID:22729652" and additional evidence is available in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G287E) has been classified as Likely pathogenic.

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]

ACMG classification

Our verdict: Pathogenic. The variant received 20 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV000915488: Riedel et al. (2012) found that protein products of the p.Gly287Val variant were unstable, had a tendency to aggregate, and retained no measurable activity, as compared to the wild type protein. PMID:22729652; SCV002555640: The variant was shown to result in a protein that was unstable, prone to aggregation, and had no measurable enzymatic activity (Riedel_2012).; SCV000937843: Experimental studies have shown that this missense change affects HOGA1 function (PMID: 22771891).; SCV004035551: Published functional studies in CHO cells demonstrate a damaging effect (Riedel et al., 2012)
• PM1: In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_138413.4
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr10-97611535-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 2149465.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 45 curated pathogenic missense variants (we use a threshold of 10). The gene has 5 curated benign missense variants. Gene score misZ: -0.2785 (below the threshold of 3.09). Trascript score misZ: 0.68417 (below the threshold of 3.09). GenCC associations: The gene is linked to primary hyperoxaluria type 3.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.752
• PP5: Variant 10-97611535-G-T is Pathogenic according to our data. Variant chr10-97611535-G-T is described in ClinVar as Pathogenic. ClinVar VariationId is 30.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
