Defects in heart valve cilia during fetal development cause mitral valve prolapse

www.sciencedaily.com

Genetic mutations in heart valve cells of the developing fetus lead to mitral valve prolapse, report a global collaborative of researchers. These mutations or genetic variations cause defects in antenna-like cellular structures called primary cilia. This finding of a developmental cause for the disease highlights the importance of early intervention and may lead to the rethinking of treatment guidelines.
