Polysplenia and asplenia typically occurs in association with situs ambiguous which is also known as heterotaxia. Situs ambiguous with asplenia (Ivemark syndrome), also referred to as right isomerism or bilateral right sidedness, is characterized by ambiguous location of the abdominal organs and congenital absence of most or all of normal splenic tissues.
Some studies have demonstrated that human orthologue of the Nodal signaling genes, ACVR2B (12), LEFTYA (13) and CFC1 (14), were mutated in patients with heterotaxia. However, the etiology in most of the patients with laterality defects (heterotaxia syndromes) is thought to be chromosomal or polygenic-multifactorial, rather than monogenic.
