Research and Characterization of New Genes Involved in Intellectual Disability

Recherche et caractérisation de Nouveaux gènes impliqués Dans la déficience Intellectuelle.

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.

Inclusion Criteria:

• for the patients: Clinical diagnosis of intellectual disbility
• for the unaffected sibs: to be aged at least 3 years
• informed consent

Exclusion Criteria:

• absence of informed consent
