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.

Rett syndrome (RTT) is a rare neurodevelopmental disorder with developmental impairments, comorbidities, and abnormal behaviours such as hand stereotypies and emotional features. The Rett Syndrome Behaviour Questionnaire (RSBQ) was developed to describe the behavioural and emotional features of RTT.
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.
We wanted to describe the range and variability in the expression of symptoms in girls and women with Rett syndrome.
We set out to describe the feeding difficulties and nutrition of girls with Rett syndrome and to examine what factors may be influencing their nutrition.
Using information from the Australian Rett Syndrome study, we examined the frequency of a range of sleep issues and variation by agegroup or gene abnormalities.
We compared the symptoms and genetic characteristics of girls with Rett syndrome and both with and without initial diagnosis of autism.
