Genes affected

RAD21 (HGNC:9811): (RAD21 cohesin complex component) The protein encoded by this gene is highly similar to the gene product of Schizosaccharomyces pombe rad21, a gene involved in the repair of DNA double-strand breaks, as well as in chromatid cohesion during mitosis. This protein is a nuclear phospho-protein, which becomes hyperphosphorylated in cell cycle M phase. The highly regulated association of this protein with mitotic chromatin specifically at the centromere region suggests its role in sister chromatid cohesion in mitotic cells.

Uncertain:1Benign:1

May 26, 2017

Geisinger Autism and Developmental Medicine Institute, Geisinger Health System

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing;provider interpretation

This 9 year old female with an intellectual disability was found to carry a missense variant in the RAD21 gene. Inheritance is unknown, as is paternal family history. She is non-dysmorphic, normocephalic, and does not have any congenital anomalies. While variable expressivity has been noted in some individuals with Cornelia de Lange Syndrome 4, this patient's lack of growth retardation, skeletal anomalies, and facial dysmorphism make it more unlikely that this is a causative variant for her intellectual disability. The variant is absent from population databases and has not been reported in any individuals with Cornelia de Lange syndrome, to our knowledge. Computational prediction models are inconsistent.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
