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.

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.

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.

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.

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.

Rare Diseases

While individual diseases are rare, as a group, rare diseases are common. Recent estimates suggest that between 3% and 6% of the world’s population are affected by rare disease.

Movement Disorders

Our vision is to increase awareness and improve outcomes for children with movement disorders and other neurodevelopmental conditions impacting on motor function.

Measurement and Resources

We aim to ensure that high quality outcome measures are available to evaluate treatments and services for children with disability rigorously. We aim to translate our research into resources to support families, carers and clinicians.

The Sibling Project

The Sibling Project focuses on the wellbeing, relationships and needs of children, adolescents and emerging adults who have a sibling with a developmental disability.
