Abstract:
:Two novel mutations in the gene encoding T-protein, a component of the glycine cleavage system, were identified in a Japanese family with nonketotic hyperglycinemia. The proband had two affected sibs, and enzymatic analysis of the liver sample from the proband revealed the T-protein deficiency. The first mutation, 183delC, was found in exon 1. One of six cytidine residues (base position 183-188) was deleted. The deletion was located in a coding region of the mitochondrial leader peptide and was deduced to create a truncated peptide with 94 amino acids. The second mutation was a base substitution from G to C at position 955 in exon 7. The G955C substitution caused an amino acid change from aspartate to histidine at position 276 (D276H). Aspartic acid at position 276 is evolutionarily conserved among human, bovine, chicken, and pea genes, and replaced by glutamic acid in Escherichia coli, suggesting that the presence of an acidic amino acid at 276 may be crucial for the enzymatic function. No base change other than the 183delC and the G955C was observed in the sequencing analysis. Familial analysis revealed that the 183delC and the D276H mutations were inherited from the father and the mother, respectively. This is the first report of T-protein gene mutation in Oriental patients with nonketotic hyperglycinemia.
