Is Ebstein's anomaly hereditary?

Ebstein's anomaly

is a congenital heart disease, the cause of which is not clear clinically, because there is no aggregated family history of the disease, and no study can show that it is related to genetic abnormalities, chromosomal abnormalities and other genetic factors, so whether Ebstein's anomaly is hereditary or not has no clear conclusion. At present, most researchers believe that the etiology of Ebstein's tricuspid valve malformation is related to electromagnetic radiation, chemical poison or intrauterine infection. Under these pathogenic factors, the normal development of embryos is disturbed, thus causing cardiac malformation.
