In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies have shown that this missense change affects D2HGDH function (PMID: 30908763, 33431826). ClinVar contains an entry for this variant (Variation ID: 158422). This missense change has been observed in individual(s) with D-2-hydroxyglutaric aciduria (PMID: 20020533). This variant is present in population databases (rs587783517, gnomAD 0.006%). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 189 of the D2HGDH protein (p.Pro189Leu).
