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.

Patterns of depressive symptoms and social relating behaviors differ over time from other behavioral domains for young people with Down syndrome

People with intellectual disabilities are at a higher risk for experiencing behavioral, emotional, and psychiatric problems in comparison with the general...

Quantitative and qualitative insights into the experiences of children with Rett syndrome and their families

Early presentation of Rett syndrome, including regression and challenges for families seeking a diagnosis

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.

The phenotype associated with a large deletion on MECP2

Multiplex ligation-dependent Probe Amplification (MLPA) has become available for the detection of a large deletion on the MECP2 gene.

Determinants of sleep disturbances in Rett syndrome: Novel findings in relation to genotype

Prevalence and determinants of sleep problems in Rett syndrome

Use of the ketogenic diet to manage refractory epilepsy in CDKL5 disorder

In view of its side effect profile, ketogenic diet (KD) administration should be supervised by a pediatric neurologist and specialist dietician.

How can clinical ethics guide the management of comorbidities in the child with Rett syndrome?

This paper reviews the disorder Rett syndrome and evidence for the management of scoliosis and poor growth within a clinical ethics framework

Seizure variables and their relationship to genotype and functional abilities in the CDKL5 disorder

Epilepsy is pervasive but not mandatory for the CDKL5 disorder, and genotype and functional abilities were related to seizure frequency

Severity Assessment in CDKL5 Deficiency Disorder

A severity assessment was rapidly developed with input from multiple stakeholders. Refinement through ongoing validation is required for future clinical trials.
