In a patient with CdLS (IV.16) we identifed a novel single basepair deletion (c.704delG) in RAD21, which encodes a cohesin pathway protein. The variant is predicted to result in a premature stop codon [p.(Ser235Ilefs*19)] and hereby would have a deleterious effect. RAD21 variants have previously been described only in five cases with cohesinopathies (b). Notably, the deletion was found in the mother and the two aunts of the index patient, and none of them had been suspected of having CdLS or a cohesinopathy prior to this study (a). The index patient can be classified as mild CdLS, but the other family members do not fulfill the diagnostic criteria of CdLS. This study together with previous reports suggests incomplete penetrance associated with RAD21 variants and these individuals may therefore be underdiagnosed.
