Visceral Heterotaxy
Abnormal left-right arrangement of the internal organs, caused by changes in genes such as ZIC3 (X-linked), NODAL, CFC1, MMP21 and PKD1L1, often with complex heart defects and spleen abnormalities.
What a diagnosis changes
Knowing about it supports heart and abdominal imaging, infection precautions if the spleen is absent, and reproductive counselling.
