Hyperglycinemia, Lactic Acidosis, And Seizures; Hgclas

Description

Hyperglycinemia, lactic acidosis, and seizures is a severe autosomal recessive disorder characterized by onset of hypotonia and seizures associated with increased serum glycine and lactate in the first days of life. Affected individuals develop an encephalopathy or severely delayed psychomotor development, which may result in death in childhood. The disorder represents a form of 'variant' nonketotic hyperglycinemia and is distinct from classic nonketotic hyperglycinemia (NKH, or GCE; {605899}), which is characterized by significantly increased CSF glycine. Several forms of 'variant' NKH, including HGCLAS, appear to result from defects of mitochondrial lipoate biosynthesis (summary by Baker et al., 2014).
