Non-ketotic hyperglycinemia

Hiperglicinemia no cetósica

Non-ketotic hyperglycinemia is an autosomal recessive disease, characterized by high concentrations of glycine in body fluids, without finding organic acids in blood or urine, which differentiates it from ketotic hyperglycinemia. The classic presentation is that of a younger infant with an overwhelming disease; Survivors often have intractable seizures associated with myoclonus and with little or no brain development. the spectrum includes different clinical phenotypes: neonatal, infantile delayed onset and transient.
