| Outline of Final Research Achievements |
Intellectual disability (ID) is commonly defined by an intelligence quotient below 70 and starts before the age of 18. ID is one of the most frequent developmental disorders in children, and its prevalence is 1-3% in the general population. However, more than half of ID was of unknown etiology due to its clinical and genetic heterogeneities. The “ID clinic” was established at the Center for Medical Genetics, Shinshu University Hospital in April 2014. We provide clinical diagnosis, genetic evaluation, and genetic counseling to patients with ID. Genetic evaluation includes chromosomal microarray analysis, targeted NGS using the panel of ID-related genes, and exome sequencing. To date, 109 patients have visited the “ID clinic” and genetic causes were identified in 27 patients (24.8%). Genetic evaluation in the “ID clinic” is thought to be useful in providing definitive diagnosis, expected clinical course, and recurrence risk to patients and their family.
