What causes fetal multicystic dysplastic kidney (MCDK)?

We do not know what causes MCDK. But, we do know that it is not caused by anything the parents did or did not do. MCDK is not anyone’s fault. It cannot be prevented before or during pregnancy. Sometimes, it can be genetic (passed down through families) if other family members also have MCDK.
