However, a few individuals affected by the syndrome may also have other family members such as a parent or siblings with the disorder. Cdls is due to pathogenetic variants in nipbl, smc1a, smc3, rad21 and hdac8 genes which belong to the cohesin pathway. The overall prognosis can be highly variable depending on the presence of other associated anomalies.

Other defects occasionally associated with cdls include congenital cardiac defects and genital. We conducted a retrospective analysis of ophthalmologic data obtained through survey responses and medical records.

The goals of our study were to identify the frequency and types of infections in cdls and to determine if underlying immunodeficiency contributes to the clinical spectrum of this syndrome. It is known that the phenotype of these patients becomes less recognizable, overlapping to features characteristic of other syndromes caused by genetic variants affecting different regulators of chromatin structure and function. The severity of the condition and the associated signs and symptoms can vary widely, but may include distinctive facial characteristics, growth delays, intellectual disability and limb defects.
