Genes affected

CRIPT (HGNC:14312): (CXXC repeat containing interactor of PDZ3 domain) This gene encodes a protein that binds to the PDZ3 peptide recognition domain. The encoded protein may modulates protein interactions with the cytoskeleton. A mutation in this gene resulted in short stature with microcephaly and distinctive facies.
