Hydrolethalus syndrome 1

Summary

Hydrolethalus-1 (HLS1) is an autosomal recessive lethal malformation syndrome characterized by hydrocephaly with absent upper midline structures of the brain, micrognathia, and polydactyly. Various other features such as cleft lip or palate, club feet, anomalies of the ears, eyes, and nose, keyhole-shaped defect in the occipital bone, abnormal genitalia, and congenital heart and respiratory organ defects have also been observed in affected individuals. Affected individuals are stillborn or die shortly after birth (summary by Mee et al., 2005).
