Rett syndrome (RTT) is a severe X-linked neurodevelopmental disorder associated with multiple neurologic impairments. Previous studies have shown challenges to the quality of life of individuals with RTT and their caregivers. However, instruments applied to quantify disease burden have not adequately captured the impact of these impairments on affected individuals and their families. Consequently, an international collaboration of stakeholders aimed at evaluating Burden of Illness in RTT was organized.

The clinical, research and advocacy communities for Rett syndrome are striving to achieve clinical trial readiness, including having fit-for-purpose clinical outcome assessments. This study aimed to (1) describe psychometric properties of clinical outcome assessment for Rett syndrome and (2) identify what is needed to ensure that fit-for-purpose clinical outcome assessments are available for clinical trials.

Rett syndrome (RTT) is a severe neurodevelopmental disorder affecting predominantly females and associated with variants in the MECP2 gene. Recent success in clinical trials have resulted in an expanded use of the Rett Syndrome Behaviour Questionnaire (RSBQ) for clinical and research purposes.

Down syndrome, also known as Trisomy 21, is one of the most common chromosome abnormalities in humans. It occurs when a child's cells end up with 47 chromosomes instead of the usual 46. Down syndrome causes intellectual disability and other physical and learning challenges.

A research collaboration between Australia and Israel has identified a genetic variation that influences the severity of symptoms in Rett syndrome.

New guidelines a model for better management of rare conditions

Girls and young women with Rett syndrome are nearly four times more likely to suffer a fracture.

A new study has found that the genetic flaw responsible for Rett syndrome can strike males, even where there isn't a family history of the rare brain disorder.

Through evidence review and the consensus of an expert panel, we developed recommendations for the clinical management of gastroesophageal reflux disease,...
