A Rare Variation of the Heterotaxy Syndrome [PDF]
Heterotaxy syndrome is a rare, complex, and confusing type of the situs anomalies. It is not possible to estimate the degree of lateralization, isomerism, and rotational variation in these types of cases.

Heterotaxy is defined as an abnormality where the internal thoraco-abdominal organs demonstrate abnormal arrangement across the left-right axis of the body. This broad term includes patients with a wide variety of very complex cardiac lesions. Patients with heterotaxy can be stratified into the subsets of asplenia syndrome and polysplenia syndrome, or ...

Mutation of ZIC3 causes X-linked heterotaxy, a syndrome in which the laterality of internal organs is disrupted. Analysis of model organisms and gene expression during early development suggests ZIC3-related heterotaxy occurs due to defects at the earliest stage of left-right axis formation.

Background: Heterotaxy syndromes encompass left and right atrial isomerism (LAI and RAI respectively) and are associated with variable cardiac and non-cardiac anomalies which greatly influence outcomes.

Heterotaxy Syndrome with Polysplenia, Fused Adrenal Glands, and Diabetes Mellitus
Heterotaxy syndrome is a rare congenital heart disease with a disarrangement of the heart and abdominal organs. We present a young African female with features of heart failure, diffuse irregular cardiac murmurs, and palpable, tender epigastric mass.

Abstract This chapter reviews background information about the incidence, risk factors, genetics, family history, recurrence risk, and epidemiology of heterotaxy and disorders of situs, including polysplenia and asplenia. The relationship between heterotaxy and dysfunction of non-motile primary cilia is explained.

Heterotaxy syndrome is an uncommon disease, with an incidence ranging from 1 in 6000 to 1 in 20,000 live births.[1] This syndrome is characterized by major cardiac vascular malformations, congenital asplenia, polysplenia, and abnormal arrangement of the chest and abdominal organs.
