Each form of intellectual disability under study is a rare disease in its own right, and it is therefore difficult to study the variability of its expression. It therefore appears necessary to study large series of patients with intellectual disabilities. The objective is to identify variants in phenotype-modifying genes in patients with intellectual disability.
