Hydrolethalus syndrome
Definition:
Hydrolethalus syndrome (HLS) is an autosomal recessive lethal malformation syndrome leading to stillbirth or death shortly after birth. HLS is characterized by hydrocephaly with absent upper midline structures of the brain, micrognathia and polydactyly. HLS is caused by mutations in HYLS1 and KIF7. Both genes code for ciliary or centriolar proteins that seem to be involved in early embryonic development of the midline.
