BACKGROUND Rett syndrome is an uncommon neurodevelopmental disorder with an incidence of 1:9,000 live female births. The principal genetic cause was first reported in 1999 when the association with mutations in the methyl-CpG-binding protein 2 (or MECP2) gene was identified. This study uses data from a large international database, InterRett, to examine(More)
R ett syndrome is an X linked dominant neurodevelopmen-tal disorder with an incidence of 1:10 000 females in Australia. 1 It is characterised by apparently normal development between 6 and 18 months, followed by a period of regression with loss of purposeful hand use, deceleration of head growth, and onset of repetitive, stereotypic hand movements. 2(More)
Movement impairment is a fundamental but variable component of the Rett syndrome phenotype. This study used video supplemented by parent report data to describe the gross motor profile in females with Rett syndrome (n=99) and to investigate the impact of age, genotype, scoliosis and hand stereotypies. Factor analysis enabled the calculation of general and(More)
Rett syndrome is a severe neurodevelopmental disorder affecting girls, caused by mutations in the MECP2 gene. There are no population-based data on the extent and determinants of health service use in this disorder. The population-based registry, the Australian Rett Syndrome database, was the source of phenotype data. This also contains data from mutation(More)
PURPOSE Rett syndrome is a neurological disorder almost exclusively affecting females. Information on its genetic basis has recently become available. However there is little information on the burden and impact of this disorder on the family despite the apparent variability in phenotype. The purpose of this study was to obtain information on the burden and(More)
This study compares bone mass in a national sample of girls with Rett syndrome (RS) with a sample of control children. The Australian RS Database was the source of cases for this population-based study. Hand radiographs were available from 101 of 137 subjects (74% of the known Australian population of girls with RS aged < or = 20 years). Control radiographs(More)
This paper describes the development of a video-based evaluation tool for use in Rett syndrome (RTT). Components include a parent-report checklist, and video filming and coding protocols that contain items on eating, drinking, communication, hand function and movements, personal care and mobility. Ninety-seven of the 169 families who initially agreed to(More)
The presence of metatarsal and metacarpal abnormalities in some individuals has raised the possibility that Rett syndrome is, in fact, a multiple congenital abnormalities/mental retardation (MCA/MR) syndrome. We have conducted radiological examination of 17 cases of Rett syndrome in Western Australia. Short fourth and/or fifth metatarsals were identified in(More)
InterRett, International Rett Syndrome Association (IRSA) Rett Phenotype Database, is a unique international project funded by the IRSA, which brings together child neurologists, geneticists, paediatricians, epidemiologists, researchers and families of affected children. The principal aim of InterRett is to increase the clinical understanding of Rett(More)
BACKGROUND Rett syndrome is a neurological disorder, almost exclusively affecting girls. METHODOLOGY Between 1993 and 1995 pedigree data were obtained from families of girls registered with the Australian Rett syndrome database. RESULTS Although 21 individual disorders were reported to be present in family members of affected girls, there was no(More)
