Invitae | RCV003015428 | SCV003302780 | pathogenic | L-2-hydroxyglutaric aciduria | 2022-03-11 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. Disruption of this splice site has been observed in individuals with L-2-hydroxyglutaric aciduria (PMID: 32626804; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 2 of the L2HGDH gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in L2HGDH are known to be pathogenic (PMID: 16134148, 20052767). |
