Isolated congenital asplenia

Isolated congenital asplenia is a rare disease in humans that can cause life-threatening bacterial infections in children due to primary immunodeficiency.[1][2][3][4] The infections can include pneumococal sepsis and meningitis.[2][5]

Isolated congenital asplenia
Other namesICAS

ICAS is a ribosomopathy,[6] due to autosomal dominant mutation of the RPSA gene on chromosome 3p21.[4][7] Unlike heterotaxy syndrome,[8] the absent spleen is not associated with other structural developmental defects.[3][4]
