Familial multiple intestinal atresia
Familial multiple intestinal atresia (FMIA) or familial intestinal polyatresia syndrome (FIPA) is an inherited disorder where atresia occurs at multiple locations throughout the small and large intestines. It presents at birth and the prognosis is very poor with almost all those diagnosed with this condition dying with one month. It may be associated with combined immunodeficiency.
