Cardiac anomalies-heterotaxy syndrome is characterized by non-compaction of the ventricular myocardium, bradycardia, pulmonary valve stenosis, and secundum atrial septal defect. Laterality sequence anomalies are also present. So far, the syndrome has been described in nine members from three generations of the same family. Transmission is autosomal dominant and linkage to chromosome 6p24.3-21.2 was reported.
Biomarker and diagnostic research for cardiac anomalies-heterotaxy syndrome has been reported in the published literature.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for cardiac anomalies-heterotaxy syndrome.
205 publications have been identified in PubMed for cardiac anomalies-heterotaxy syndrome. Research spans Review / Meta-Analysis (40%), Basic Science / Preclinical (32%), and Epidemiology / Natural History (11%).
