Using Population Data to Explore Sibling Profiles in Families of Children With and Without Neurodevelopmental Conditions

Sibling profiles, including sibling status (only-child or sibling) and sibling characteristics (sibling size, birth order, and sex), can impact on lived experiences and social interactions, and operate as protective or risk factors for a wide range of health and well-being indicators and outcomes. Using population-based data linkage to disability-specific databases, sibling profiles were compared between families of children with and without neurodevelopmental conditions.

Maternal life events during pregnancy and offspring language ability in middle childhood

There is accumulating evidence for a link between maternal stress during pregnancy and later behavioural and emotional problems in children.

Down syndrome or Rett syndrome in the family: Parental reflections on sibling experience

Siblings of children with intellectual disability have unique family experiences, varying by type of disability.

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.

Development of an International Database for a Rare Genetic Disorder: The MECP2 Duplication Database (MDBase)

The natural history of MECP2 duplication syndrome (MDS), a rare X-linked neurodevelopmental disorder with an estimated birth prevalence of 1/150,000 live births, is poorly understood due to a lack of clinical data collected for research. Such information is critical to the understanding of disease progression, therapeutic endpoints and outcome measures for clinical trials, as well as the development of therapies and orphan products.

The Lived Experience of Parents’ Receiving the Diagnosis of CDKL5 Deficiency Disorder for Their Child

CDKL5 deficiency disorder (CDD), a severe developmental and epileptic encephalopathy, is being diagnosed earlier with improved access to genetic testing, but this may also have unanticipated impacts on parents’ experience receiving the diagnosis. This study explores the lived experience of parents receiving a diagnosis of CDD for their child using mixed methods.

Exploring genotype-phenotype relationships in the CDKL5 deficiency disorder using an international dataset

Characterized by early-onset seizures, global developmental delay and severe motor deficits, CDKL5 deficiency disorder is caused by pathogenic variants in the cyclin-dependent kinase-like 5 gene. Previous efforts to investigate genotype-phenotype relationships have been limited due to small numbers of recurrent mutations and small cohort sizes. Using data from the International CDKL5 Disorder Database we examined genotype-phenotype relationships for 13 recurrent CDKL5 variants and the previously analyzed historic variant groupings. We have applied the CDKL5 Developmental Score (CDS) and an adapted version of the CDKL5 Clinical Severity Assessment (CCSA), to grade the severity of phenotype and developmental outcomes for 285 individuals with CDKL5 variants.

Quantification of walking-based physical activity and sedentary time in individuals with Rett syndrome

Quantifying individual's with Rett syndrome with the ability to walk, walking based activities and sedentary time, analyzing a variety of influences.

Expanding the clinical picture of the MECP2 Duplication syndrome

People with two or more copies of MECP2 gene, located at Xq28, share clinical features and a distinct facial phenotype called MECP2 Duplication syndrome.

Impacts of caring for a child with the CDKL5 disorder on parental wellbeing and family quality of life

Investigate impacts on maternal health and family quality of life in families with a child with the CDKL5 disorder
