ICD-11 definition : Formiminoglutamic aciduria, in its moderate form and in the absence of histadine administration,
is characterized by mild developmental delay and elevated concentrations of formiminoglutamate
(FIGLU) in the urine. A more severe phenotype has been described in five members of
a Japanese family and included severe intellectual deficit, psychomotor retardation
and megaloblastic anemia. Formiminoglutamic aciduria is an autosomal recessive disease
caused by a deficiency of glutamate formiminotransferase-cyclodeaminase (FTCD), an
enzyme involved folic acid metabolism.;
