Active clinical trials for "Intellectual Disability"

Development of a new mass spectrometry-based biomarker for the ear-ly and sensitive diagnosis of the Creatine Deficiency Syndromes from dry-blood-spot sample

Development of a new MS-based biomarker for the ear-ly and sensitive diagnosis of Sanfilippo Disease Type A-B-C-D from blood (plasma)

The aim of this study is to investigate short and long term consequences from early postnatal HCMV infection transmitted via human milk in very preterm infants (birth weight < 1500 g or gestational age < 32 weeks). These infants are at high risk of early death or survival with chronic disease and neurodevelopmental impairment if infected with HCMV. Infection is a common complication in this group of patients and reported to be the most frequent cause of death after the second week of life. Systemic infection in the newborn period is reported as representing an independent risk factor for survival with neurodevelopmental impairment among very preterm infants.

16p13.11 copy number variations are considered as predisposition factors for neurodevelopmental disorders but can be inherited from normal parents. SEESIC aims at identifying seond molecular events by exome sequencing that could modulate the phenotype and explain familial discrepancies.

CDK13 related disorder is mainly characterised by developmental delay (DD) and intellectual disability (ID), ranging from mild to severe, and malformation syndrome. The aims of this study are first to better delineate the clinical phenotype, as well as the neuropsychological profile, and the brain MRI characteristics; and, second, to study the epigenetic signatures in a cohort of individuals with CDK13 intragenic pathogenic variants. This work will conduct to a MD thesis of a clinical resident geneticist in France. Physician that will participate will fill an Excel sheet regarding the clinical and neuropsychological assessment. The investigators will be also happy to have either CD-ROM or a link to have access to the brain MRI data as well as a DNA sample with a minimum 0.5ug of peripheral blood genomic DNA. The investigators will gather the DNA in Montpellier genetic lab (Dr Mouna BARAT) and send the batch to the Dr Sadikovic' lab. Between 2019 and 2020, The investigators have already recruited data from individuals with CDK13 pathogenic variants from France and several European genetic centres.

To evaluate the demographic characteristics of patients suffering from mental retardation or cerebral palsy in the Israeli Arab community. Specific questionnaires will be developed and will be distributed amongst this population in order to identify these characteristics.

This is a a study to identify inherited disease genes. The study will use molecular techniques to map genetic diseases using techniques such as Affymetrix SNP chips. The powerful combination of the information generated by the Human Genome Project and technical advances such as microarrays enables attempts to identify genes responsible for inherited disorders more possible than ever before. Starting with even modest pedigrees of only a few individuals, or even single individuals, it is possible to identify the gene(s) involved. It is proposed to collect up to 20 ml of peripheral blood and/or buccal cell samples from subjects and relevant family members. Currently the following disorders are approved for investigation. The current list of disorders: Aarskog-Scott syndrome, Café-au-Lait spots, Cerebral cavernous malformation, delXp, del2q, del10p, del11q, del12p, del13q, del14q, del16q, del17q, del18q, del Xp21, Choreoathetosis, Congenital Vertical Talus (CVT), Clubfoot, Tarsal coalition and other congenital limb deformities, Cystic Fibrosis (CF)-like disease, Desbuquois syndrome, Droopy Eyelid syndrome (Ptosis), Fanconi-Bickel syndrome (FBS), FENIB (familial encephalopathy with neuroserpin inclusion bodies), FG syndrome, Idiopathic generalised epilepsy (IGE), Renpenning syndrome, transient neonatal diabetes with 6q UPD, translocation (13;14), translocation (3;8), translocation (2;18), Uncharacterized familial dementia and X-linked mental retardation (XLMR).

This study evaluates the types of dental procedures performed in general anaesthesia for adult persons with intellectual disability, as well as factors affecting the decision to perform the dental treatment in general anaesthesia, factors contributing to tooth loss and possibilities to perform oral rehabilitation procedures

To assess the indications and diagnostic efficiency of whole genome sequencing (WGS) in pediatric patients with unexplained intellectual disability/developmental delay, multiple congenital abnormalities and other rare and undiagnosed diseases

The purpose of this study is to describe facial, behavioral and physiologic (heart rate) reactivity of children with autism aged 3 to 6 years old, during a painful stimulation (venepuncture). Children will be videotaped before, during and after a venepuncture. Each recording will be rated with the FACS (Facial Action Coding System) and the NCCPC (Non Communicating Children's Pain Checklist).
