New rare neurodevelopmental disease and its genetic cause discovered

Researchers from hospitals and research centres around the world have discovered a new rare neurodevelopmental disease. The disease is caused by a defect in the ESAM gene, which manifests as disruption of the blood-brain barrier. Affected individuals suffer from profound global developmental delay/unspecified intellectual disability, epilepsy, absent or severely delayed speech, varying degrees of spasticity, ventriculomegaly and intracranial haemorrhage/brain calcifications.

These technologies make it possible to determine the cause in a considerable proportion (up to 40%) of undiagnosed patients, and more importantly, often with findings that allow therapeutic measures to be taken to tackle the disease.

Intellectual disability: what is it, types, causes and diagnosis?

What is intellectual disability? Intellectual disability (ID) is the result of a disturbance in human development that appears before the age of 18. It is characterised by a significant limitation in intellectual functioning and adaptive behaviour. In other words, the concept encompasses people whose cognitive resources are often less than expected for their chronological age. What types of intellectual disabilities
