We describe change in gross motor function over 3 to 4 years for 70 subjects participating in the Australian Rett Syndrome Database

The relationship between MECP2 mutation type and health status and service use trajectories over time in a Rett syndrome population

This study aimed to investigate the trajectories over time of health status and health service use in Rett syndrome by mutation...

Rett Syndrome Behaviour Questionnaire: Variability of Scores and Related Factors

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.

Burden of illness in Rett syndrome: initial evaluation of a disorder-specific caregiver survey

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.

International workshop: what is needed to ensure outcome measures for Rett syndrome are fit-for-purpose for clinical trials? June 7, 2023, Nashville, USA

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.

Bone mineral content and density in Rett syndrome and their contributing factors

This study used densitometry to investigate the areal bone mineral density (aBMD) and bone mineral content (BMC) in an Australian Rett syndrome cohort...

Measuring use and cost of health sector and related care in a population of girls and young women with Rett syndrome

This study measured use and cost of health sector and related services in Rett syndrome and effects of socio-demographic, clinical severity and genetic factors

Longitudinal hand function in Rett syndrome
