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);

Prefixed ID : #200990;
