FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the homolog of the Drosophila melanogaster Nipped-B gene product and fungal Scc2-type sister chromatid cohesion proteins. The Drosophila protein facilitates enhancer-promoter communication of remote enhancers and plays a role in developmental regulation. It is also homologous to a family of chromosomal adherins with broad roles in sister chromatid cohesion, chromosome condensation, and DNA repair. The human protein has a bipartite nuclear targeting sequence and a putative HEAT repeat. Condensins, cohesins and other complexes with chromosome-related functions also contain HEAT repeats. Mutations in this gene result in Cornelia de Lange syndrome, a disorder characterized by dysmorphic facial features, growth delay, limb reduction defects, and mental retardation. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
PHENOTYPE: Nullizygous mice are embryonic lethal. Heterozygous null mice are growth-retarded and show various skeletal anomalies. Heterozygotes for a gene-trap allele are small and show craniofacial, heart, eye, hearing and behavioral defects, delayed bone maturation, reduced body fat, and postnatal mortality.
