Research collaborators

The development of research partnerships is a priority for InterRett, with centres or clinicians with access to large numbers of patients with Rett syndrome.

Intellectual Disability

About 2 per cent of children are estimated to have an intellectual disability. The cause of the condition is unknown in at least 50 per cent of cases.

Rett Syndrome

A severe neurodevelopmental disorder mostly affecting girls.

Longitudinal Rett syndrome behaviour questionnaire scores and their associations with genotype and trajectories of mobility, weight and seizure frequency status

The Rett Syndrome Behaviour Questionnaire (RSBQ) describes behavioural and emotional features. This study investigated total RSBQ score trajectories and their clustering, and for trajectory groups, relationships with genotype and mobility, weight-for-age z scores, and seizure frequency.

Longitudinal trajectory of gross motor skills in school-aged children with Rett syndrome

In children with Rett syndrome, this study aimed to (1) describe gross motor skill trajectories; and (2) analyse the influences of genetic variant and comorbidities. This was a prospective longitudinal study conducted at the Danish National Center for Rett Syndrome 2008 to 2022. The Rett Syndrome Gross Motor Scale (RSGMS) was administered, and clinical data collected at each visit.

Real-world benefits and tolerability of trofinetide for the treatment of Rett syndrome: The LOTUS study

Aim: To describe the real-world effects of trofinetide in individuals with Rett syndrome (RTT) using the 18-month follow-up analysis of the LOTUS study.

Enablers and barriers in dental attendance in Rett syndrome: an international observational study

Intellectual and developmental disabilities are heterogeneous in aetiology and presentation, and one cannot make assumptions about the oral health barriers of those with Rett syndrome (RTT) based on findings from generic studies. This study investigated caregivers' perceptions regarding access to dental care for those with RTT, and associations of dental treatments received by those with RTT with their caregivers' perceived value of oral health and perception of their own as well as their daughter's dental anxiety.

Improving clinical trial readiness to accelerate development of new therapeutics for Rett syndrome

Rett syndrome is associated with severe functional impairments and many comorbidities, each in urgent need of treatments. Mutations in the MECP2 gene were identified as causing Rett syndrome in 1999. Over the past 20 years there has been an abundance of preclinical research with some studies leading to human clinical trials.

Determinants of quality of life in Rett syndrome: New findings on associations with genotype

Rett syndrome is a genetically caused neurodevelopmental disorder associated with functional deficits and comorbidities. This study investigated relationships between genotype, functional abilities and comorbidities and quality of life in Rett syndrome.

Decline in gross motor skills in adult Rett syndrome; results from a Danish longitudinal study

Longevity of individuals with neurodevelopmental diseases as Rett syndrome (RTT) has increased and many reach adulthood and old age. There is therefore a need to increase knowledge about the course of RTT in adults in order to improve medical care management and quality of life.
