Research and Characterization of New Genes Involved in Intellectual Disability

Completed
Conditions
Intellectual Disability
Interventions
Genetic: gene analysis
Registration Number
NCT01867554
Lead Sponsor
Institut National de la Santé Et de la Recherche Médicale, France
Brief Summary

Intellectual disability (ID) occurs in 2 to 3 % of the general population but the cause is identified only in 30 to 60% of cases.

The purpose of this study is to indentify genes involved in ID with new genetics tools (SNP-arrays, next generation sequencing...) and establish genotype-phenotype correlations.
