title: Congenital isolated folic acid malabsorption.
abstract: We report a case of congenital isolated malabsorption of folic acid, the first in a boy. Only seven previous cases have been reported, and we discuss two aspects--namely, the tendency to infection, with evidence of impairment of both cellular and humoral immunity, and the absence of neurological disturbances.
