Clinical guidelines for management of bone health in rett syndrome based on expert consensus and available evidence

A clinically significant history of fracture in combination with low bone densitometry findings is necessary for a diagnosis of osteoporosis in Rett Syndrome

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...

Spinal fusion in girls with Rett syndrome: Post-operative recovery and family experiences

Rett syndrome is a severe neurodevelopmental disorder mainly affecting females and scoliosis is a common co-morbidity. Spinal fusion may be recommended if...

Prevalence, clinical investigation, and management of gallbladder disease in Rett syndrome

This study determined the prevalence of cholelithiasis and/or cholecystectomy in Rett syndrome, described gallbladder function in a clinical cohort, and...

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.

How Families Manage the Complex Medical Needs of Their Children with MECP2 Duplication Syndrome

MECP2 duplication syndrome (MDS) is a rare, X-linked, neurodevelopmental disorder resulting from the duplication of the methyl-CpG-binding protein 2 (MECP2) gene. The clinical features of MDS include severe intellectual disability, global developmental delay, seizures, recurrent respiratory infections, and gastrointestinal problems. The aim of this qualitative study was to explore how the parents of children with MDS manage their child's seizures, recurrent respiratory infections, and gastrointestinal symptoms, and the impact on them as parents.

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.

Functional skills in MECP2 duplication syndrome: developmental dynamics and regression

MECP2 duplication syndrome (MDS) is an ultrarare, X-linked neurodevelopmental disorder that is poorly understood in terms of its natural history and phenotypic variability. There is limited information on how individuals with MDS acquire, retain or lose fundamental functional skills (gross motor, purposeful hand function and communication) - that of which this study aimed to better characterise in the largest case series to date.

Measuring the Burden of Epilepsy Hospitalizations in CDKL5 Deficiency Disorder

Information on the hospital service use among individuals with CDKL5 Deficiency Disorder, an ultrarare developmental epileptic encephalopathy, is limited, evidence of which could assist with service planning. Therefore, using baseline and longitudinal data on 379 genetically verified individuals in the International CDKL5 Disorder Database, we aimed to investigate rates of seizure-related and other hospitalizations and associated length of stay in this cohort.
