Hydrolethalus Syndrome 2; Hls2

Description

Hydrolethalus syndrome is an autosomal recessive embryonic lethal disorder characterized by hydrocephaly or anencephaly, postaxial polydactyly of the upper limbs, and pre- or postaxial polydactyly of the lower limbs. Duplication of the hallux is a common finding. HLS2 is considered a ciliopathy (summary by Putoux et al., 2011).Acrocallosal syndrome (ACLS ) is an allelic disorder with a less severe phenotype.For a discussion of genetic heterogeneity of hydrolethalus syndrome, see {236680}.
