== Disease ==
[https://www.uniprot.org/uniprot/GLNA_HUMAN GLNA_HUMAN] Defects in GLUL are the cause of congenital systemic glutamine deficiency (CSGD) [MIM:[https://omim.org/entry/610015 610015]. CSGD is a rare developmental disorder with severe brain malformation resulting in multi-organ failure and neonatal death. Glutamine is largely absent from affected patients serum, urine and cerebrospinal fluid.<ref>PMID:16267323</ref> 
== Function ==
[https://www.uniprot.org/uniprot/GLNA_HUMAN GLNA_HUMAN] This enzyme has 2 functions: it catalyzes the production of glutamine and 4-aminobutanoate (gamma-aminobutyric acid, GABA), the latter in a pyridoxal phosphate-independent manner (By similarity). Essential for proliferation of fetal skin fibroblasts.<ref>PMID:18662667</ref>
