The aim of this study is to determine if allele specific gene expression (skewing away from expected 50:50 ratio) contributes to phenotypic variability in tuberous sclerosis complex. We are studying familial cases where all affected individuals have the same mutation, and relate phenotypic severity (clinical score) to blood measure of allelic skewing of the corresponding TSC gene (mutant:wild-type allele ratio). We are recruiting multiplex families with TSC into this study.
