In 16 of the 36 families with GLDC mutations, mutations were identified in only 1 allele despite sequencing of the entire coding regions. The GLDC gene consists of 25 exons. Seven of the 32 GLDC missense mutations were clustered in exon 19, which encodes the cofactor-binding site lys754. A large deletion involving exon 1 of the GLDC gene was found in Caucasian, Asian, and black families. Multiple origins of the exon 1 deletion were suggested by haplotype analysis with 4 GLDC polymorphisms. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=16450403" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<p>The enzyme system for cleavage of glycine (glycine cleavage system; GCS; EC 2.1.2.10), which is confined to the mitochondria, is composed of 4 protein components: P protein (a pyridoxal phosphate-dependent glycine decarboxylase), H protein (a lipoic acid-containing protein, 238330), T protein (a tetrahydrofolate-requiring enzyme, 238310), and L protein (a lipoamide dehydrogenase, 238331).</p>

<p>Kume et al. (1991) cloned the cDNA encoding human glycine decarboxylase, P protein. The deduced protein contains 1,020 amino acids. By RNA blot analysis, Takayanagi et al. (2000) demonstrated that GLDC is expressed in human liver, kidney, brain, and placenta. By dot-blot analysis, Kure et al. (2001) detected expression of GLDC in a limited number of tissues with strong expression in liver, placenta, and kidney; moderate expression in brain, small intestine, thyroid gland, and pituitary gland; and weak expression in colon, bladder, and lung. </p>

<strong>Gene Structure</strong>

<span class="mim-text-font">
<p>Takayanagi et al. (2000) determined the structure of the GLDC gene and its pseudogene. The GLDC gene spans at least 135 kb and contains 25 exons. All donor and acceptor sites adhered to the canonical GT-AG rule, except for the donor site of intron 21, where a variant form GC is used instead of GT. By primer extension analysis, the transcription initiation site was assigned to a residue 163 bp upstream from the translation initiation triplet. The GLDC pseudogene has no introns and shares 97.5% homology with the coding region of functional GLDC, suggesting that it is a processed pseudogene that arose from the GLDC transcript about 4 to 8 million years ago. </p>

<strong>Pathogenesis</strong>

<span class="mim-text-font">
<p>Kim et al. (2015) identified a key role for serine and glycine metabolism in the survival of brain cancer cells within the ischemic zones of gliomas. In human glioblastoma multiforme (137800), SHMT2 (138450) and GLDC are highly expressed in the pseudopalisading cells that surround necrotic foci. Kim et al. (2015) found that SHMT2 activity limits that of PKM2 (179050) and reduces oxygen consumption, eliciting a metabolic state that confers a profound survival advantage to cells in poorly vascularized tumor regions. GLDC inhibition impairs cells with high SHMT2 levels, as the excess glycine not metabolized by GLDC can be converted to the toxic molecules aminoacetone and methylglyoxal. Kim et al. (2015) concluded that SHMT2, which is required for cancer cells to adapt to the tumor environment, also renders these cells sensitive to glycine cleavage system inhibition. </p>

<p>Bodkin et al. (2019) conducted a proof-of-principle clinical trial on a mother and son with a complex rearrangement of chromosome 9p24 that included triplication of the GLDC gene (Grochowski et al., 2018). The mother had been diagnosed with bipolar disorder with psychotic features, and the son with schizoaffective disorder. As triplication of GLDC could be expected to result in low levels of brain glycine and D-serine, causing hypofunctioning of the NMDAR receptor channel, Bodkin et al. (2019) undertook the trial to determine whether augmentation of usual psychotropic drug treatment with glycine, a full agonist at the NMDAR glycine modulatory site (GMS), reduced psychotic and mood symptoms in these 2 carriers. Bodkin et al. (2019) performed 2 double-blind placebo-controlled trials in both patients, keeping all other psychotropic medications stable throughout the 6-week trials: one of supplemental glycine at a target dose of 0.8 gm/kg/day, and one of D-cycloserine. Both agents resulted in improved psychotic and mood symptoms in both patients. Glycine dosing at the proposed level was not well tolerated, but was well tolerated and effective at 0.6 gm/kg/day. </p>

<p>A high frequency of glycine encephalopathy (GCE1; 605899) has been found in some counties of Finland (von Wendt and Simila, 1980). In 13 heterozygotes in Finland, von Wendt et al. (1981) found minor dysfunctions of the central nervous system which they suggested may be due to a slightly abnormal degradation of glycine (which has a neurotransmitter role). In a patient with GCE, Kure et al. (1992) identified homozygosity for a G to T in the protein coding region of the GLDC gene, which resulted in an amino acid alteration from serine-564 to isoleucine (S564I; 238300.0001). Kure et al. (1992) found that 14 of 20 P protein alleles in Finnish patients carried this single nucleotide substitution. </p><p>Using the GCSP cDNA as a probe in Southern blot analysis of genomic DNA from 2 patients with nonketotic hyperglycinemia, Tada et al. (1990) showed that they had a specific defect in P protein, namely, a partial deletion. </p><p>Toone et al. (2000) identified a recurrent mutation in the P protein, R515S (238300.0004), in 2 unrelated patients with glycine encephalopathy. </p><p>In patients with glycine encephalopathy, Applegarth and Toone (2001) confirmed 9 mutations in the T protein (AMT; 238310) and 8 mutations in the P protein. They also reviewed 7 cases of transient NKH. </p><p>Kure et al. (2006) undertook a comprehensive screening for mutations in the P, T, and H enzymes in 69 families (56, 6, and 7 families with neonatal, infantile, and late-onset type NKH, respectively). GLDC or AMT mutations were identified in 75% of neonatal and 83% of infantile families, but not in late-onset type NKH. No GCSH mutation was identified in this study. GLDC mutations were identified in 36 families, and AMT mutations were detected in 11 families. In 16 of the 36 families with GLDC mutations, mutations were identified in only 1 allele despite sequencing of the entire coding regions. The GLDC gene consists of 25 exons. Seven of the 32 GLDC missense mutations were clustered in exon 19, which encodes the cofactor-binding site lys754. A large deletion involving exon 1 of the GLDC gene was found in Caucasian, Asian, and black families. Multiple origins of the exon 1 deletion were suggested by haplotype analysis with 4 GLDC polymorphisms. </p>

By fluorescence in situ hybridization using genomic clones, Isobe et al. (1994) assigned the functional GCSP gene to 9p24-p23 and a processed pseudogene to 4q12. Sakakibara et al.

<p>Glycine encephalopathy (GCE1; 605899) is said to have an incidence of 1 in 12,000 births in northern Finland (von Wendt et al., 1979). Kure et al. (1992) demonstrated that the defect is in the P protein and that a G-to-T mutation resulting in substitution of isoleucine for serine-564 accounts for 14 of 20 P protein alleles. Activity of P protein was undetectable in the lymphoblasts, while P protein mRNA of a normal size and level was present. The S564I mutation was found in homozygous state in 5 patients, while 4 other patients were probably compound heterozygotes. </p>

<p>Takayanagi et al. (2000) studied a Japanese boy with glycine encephalopathy (GCE1; 605899) of neonatal onset. The parents were not known to be related and were from the Aichi prefecture in the central area of Japan. Convulsive seizures and respiratory distress developed at 3 days of age. Administration of ketamine improved his electroencephalographic findings and hyperirritability. His psychomotor development was, however, severely delayed. He never gained head control or walked, and joint contractures developed. At 9 years of age he died of influenzal pneumonia and renal failure. An enzymatic analysis of an autopsied liver specimen revealed that he was completely deficient in GLDC activity. Takayanagi et al. (2000) found that exons 1-3 of the functional GLDC gene from this patient were not amplified by PCR, whereas those from control subjects were. These results suggested a large homozygous deletion (at least 30 kb) in the patient. Takayanagi et al. (2000) devised a semiquantitative PCR to estimate the number of GLDC alleles by using the pseudogene as an internal control and confirmed the homozygosity and heterozygosity of the deletion in the patient and his parents, respectively. </p>

<p>In 4 affected patients from 2 unrelated families with glycine encephalopathy (GCE1; 605899), Korman et al. (2004) identified a homozygous 2405C-T transition in exon 20 of the GLDC gene, resulting in an ala802-to-val (A802V) substitution at a highly conserved residue. Functional expression studies of the mutation in COS-7 cells showed that mutant protein activity was reduced to 32% of control levels. The authors noted that 32% residual activity is markedly different from the S564I mutation (238300.0001), which has virtually no enzyme activity. The phenotype of the affected patients with the A802V mutation was unique: 3 patients from 1 family had complete resolution of symptoms and developed normally, whereas the fourth patient had only mild neurologic sequelae. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
