L-2-hydroxyglutaric aciduria Uncertain:1
This sequence change creates a premature translational stop signal (p.Ala442Leufs*11) in the L2HGDH gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 22 amino acid(s) of the L2HGDH protein. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with L2HGDH-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
