Medical Comorbidities in MECP2 Duplication Syndrome: Results from the International MECP2 Duplication Database

Since the discovery of MECP2 duplication syndrome (MDS) in 1999, efforts to characterise this disorder have been limited by a lack of large datasets, with small case series often favouring the reporting of certain conditions over others. This study is the largest to date, featuring 134 males and 20 females, ascertained from the international MECP2 Duplication Database (MDBase).

A brief history of MECP2 duplication syndrome: 20-years of clinical understanding

MECP2 duplication syndrome (MDS) is a rare, X-linked, neurodevelopmental disorder caused by a duplication of the methyl-CpG-binding protein 2 (MECP2) gene-a gene in which loss-of-function mutations lead to Rett syndrome (RTT). MDS has an estimated live birth prevalence in males of 1/150,000.

CDKL5 deficiency disorder: clinical features, diagnosis, and management

CDKL5 deficiency disorder (CDD) was first identified as a cause of human disease in 2004. Although initially considered a variant of Rett syndrome, CDD is now recognised as an independent disorder and classified as a developmental epileptic encephalopathy.

A longitudinal examination of perinatal testosterone, estradiol and vitamin D as predictors of handedness outcomes in childhood and adolescence

The developmental origins of handedness remain elusive, though very early emergence suggests individual differences manifesting in utero could play an important role. Prenatal testosterone and Vitamin D exposure are considered, yet findings and interpretations remain equivocal.

Implications of providing wrist-hand orthoses for children with cerebral palsy: evidence from a randomised controlled trial

To investigate the effects of providing rigid wrist-hand orthoses plus usual multidisciplinary care, on reducing hand impairments in children with cerebral palsy.

A qualitative exploration of motivations and barriers for community leisure organisations’ engagement with the Jooay™ mobile app

Participation in leisure activities is key to the physical and mental health of children and adolescents with disabilities. The Jooay™ mobile app aims to link children and adolescents with disability to participation opportunities in their community.

"Capturing the magic": identifying the active ingredients of a physical activity participation intervention for children and youth with disabilities

This study aimed to define the active ingredients of a participation-focused physical activity intervention for children and youth with disabilities.

Common data elements to standardize genomics studies in cerebral palsy

To define clinical common data elements (CDEs) and a mandatory minimum data set (MDS) for genomic studies of cerebral palsy (CP). Method: Candidate data elements were collated following a review of the literature and existing CDEs.

Associations between genotype, phenotype and behaviours measured by the Rett syndrome behaviour questionnaire in Rett syndrome

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.

Using Focussed Ethnography to Observe and Understand the Actions and Interactions of People With Prader-Willi Syndrome When They Exercise at a Community Gym: A Protocol

Exercise for people with Prader-Willi syndrome (PWS) is important for their health and wellbeing and can provide opportunities for community participation. However, they may find it difficult to participate in some contexts, such as community gyms because social and environmental barriers in these settings may compound difficulties caused by physical impairments or intellectual disability.
