Red List (low evidence)

Associated with Atypical glycine encephalopathy, Infantile glycine encephalopathy and Neonatal glycine encephalopathy in Orphanet, which are also linked to the AMT and GLDC genes which are both green in this panel and for which there are multiple cases from screens of patients which did not find variants within GCLC. PMID:12402263 describes a heterozygous variant identified in a patient with transient neonatal hyperglycinemia, which was also present in his mother and brother who had no family history of the disorder. Reported with a possible G2P association with MIM 605899. Not enough evidence at this time to be promoted.
