Official title
Williams Syndrome SHAAPE STUDY [Strength, Hormones, Activity & Adiposity, DNA Programming, Eating Study]
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Williams syndrome (WS) is a rare microdeletion genetic disorder that has a broad phenotype including many endocrine and metabolic abnormalities. Dr. Pober and colleagues at MGH have reported the following findings in adults with WS: abnormal body composition (excess body fat accumulation with a lipedema phenotype), decreased bone mineral density, abnormal glucose tolerance, and reduced lean mass. Despite the high prevalence and potential effect of metabolic abnormalities on the health of persons with WS, their full phenotypic range, potential causal factors (either genetic and/or hormonal) along with their impact on other aspects of health (such as risk of falls and fractures or interaction with emotional behavioral concerns) remain incompletely characterized. The purpose of the current study in a large cohort of subjects with WS is to: collect further information to characterize the timing of onset and distribution of body fat; better characterize hormonal status of WS subjects; and screen for genetic variation using single-nucleotide-polymorphism (SNP) analysis that could elucidate genetic contributors to the lipedema phenotype as well as the other observed metabolic and bone abnormalities.
