Although organisms appear bilaterally symmetrical when observed from the outside, internal organs are positioned asymmetrically along the left—right axis, and the...

The discovery could lead to new treatments for those affected by the conditions brought on by the birth defect. Princeton researchers focused on identifying and studying the gene in zebrafish embryos, and the team's work expanded to include collaborations with other groups studying the genetics of mice and people....

While the condition is usually benign, Eigel needed a transplant because his heart was failing for reasons unrelated to the condition,...
