Rady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego RCV000853347 SCV000996209 pathogenic Metaphyseal chondromatosis with D-2-hydroxyglutaric aciduria 2018-11-02 criteria provided, single submitter clinical testing This variant has been previously reported as a mosaic change in patients with metaphyseal chondromatosis and elevated D-2-hydroxyglutaric aciduria (PMID: 24049096, 22025298). It is absent from the gnomAD population databases and thus is presumed to be rare. The c.395G>A, p.Arg132H variant affects a highly conserved amino acid and is predicted by multiple in silico tools to have a deleterious effect on protein function. The p.Arg132H variant results in loss of its native enzymatic activity and gain of alternative enzymatic activity (producing D-2-hydroxyglutarate) (PMID 21446021). Structural studies demonstrated that when p.Arg132 is mutated to histidine (R132H), residues in the active site are shifted to produce structural changes consistent with reduced oxidative decarboxylation of isocitrate and acquisition of the ability to convert alpha-ketoglutarate to 2HG (PMID 19935646). Excess accumulation of 2HG has been shown to lead to an elevated risk of malignant brain tumors in patients with inborn errors of 2HG metabolism (PMID 18931888). Based on the available evidence, the c.395G>A, p.Arg132H variant is classified as Pathogenic.
