Description : The acrocallosal syndrome is an autosomal recessive mental retardation syndrome with
brain abnormalities such as corpus callosum agenesis and/or Dandy-Walker malformation
as well as dysmorphic features, postaxial polydactyly of the hands, and preaxial polydactyly
of the feet (Schinzel and Schmid, 1980). It is considered a ciliopathy (Putoux et
al., 2011). Joubert syndrome-12 is a disorder with an overlapping phenotype characterized
by the hallmark finding of the molar tooth sign (MTS) on brain MRI. For a phenotypic
description and a discussion of genetic heterogeneity of Joubert syndrome, see 213300.
Hydrolethalus-2 (HLS2; 614120) is an allelic disorder with a more severe phenotype
and death in utero.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the kinesin family member 7 gene (KIF7, 611254.0001);
