Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000674479 SCV000966999 likely pathogenic Non-ketotic hyperglycinemia 2018-10-09 criteria provided, single submitter clinical testing The p.Ala678del variant in GLDC has been reported in one individual with glycine encephalopathy who carried a deletion of exons 3-21 in trans (Swanson 2015). It has also been identified in 1/111670 of European chromosomes by gnomAD (http:// This variant is a deletion of one amino acid at posi tion 678 and is not predicted to alter the protein reading-frame. In summary, al though additional studies are required to fully establish its clinical significa nce, the p.Ala678del variant is likely pathogenic.
