Genes affected
NIPBL (HGNC:28862): (NIPBL cohesin loading factor) 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 cognitive disability. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

NIPBL-related disorder Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesMay 18, 2023The NIPBL c.1808dupA variant is predicted to result in a frameshift and premature protein termination (p.Ser604Valfs*2). To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. Frameshift variants in NIPBL are expected to be pathogenic. This variant is interpreted as likely pathogenic. -
