Hydrolethalus syndrome

Hydrolethalus syndrome (less commonly referred to as Salonen-Herva-Norio syndrome) is a rare genetic disorder that causes improper fetal development, resulting in birth defects and often stillbirth.^[1]

It is associated with HYLS1 mutations.

Symptoms

Hydrolethalus syndrome can cause heart and brain defects, a cleft lip or palate, an abnormally shaped nose or jaw, or incomplete lung development. These defects are typically serious enough to cause stillbirth or death within a few days of birth.
