MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Degradation of glycine is brought about by the glycine cleavage system, which is composed of four mitochondrial protein components: P protein (a pyridoxal phosphate-dependent glycine decarboxylase), H protein (a lipoic acid-containing protein), T protein (a tetrahydrofolate-requiring enzyme), and L protein (a lipoamide dehydrogenase). The protein encoded by this gene is the P protein, which binds to glycine and enables the methylamine group from glycine to be transferred to the T protein. Defects in this gene are a cause of nonketotic hyperglycinemia (NKH).[provided by RefSeq, Jan 2010]
PHENOTYPE: Hypomorphic mutants show a developmental delay, hyperglycinemia, altered folate profiles, neural tube defects and postnatal lethality, while survivors show hydrocephaly and premature death. Homozygotes for an ENU allele show omphalocele and severe cardiovascular, craniofacial, renal and eye defects. [provided by MGI curators]

Nature of Mutation

Two transcripts of the Gldc gene are displayed on Ensembl.

Protein Function and Prediction

The Gldc gene encodes the 1025 amino acid mitochondrial P protein (a pyridoxal phosphate-dependent glycine decarboxylase) that is part of the glycine cleavage system. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO2 is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein (Uniprot Q91W43). Mutations in human GLDC causes glycine encephalopathy (OMIM 605899).
