Functional assessment of variants in the TSC1 and TSC2 genes identified in individuals with Tuberous Sclerosis Complex
Résumé
The effects of missense changes and small in-frame deletions and insertions on protein function are not easy to predict and the identification of such variants in individuals at risk of a genetic disease can complicate genetic counselling. One option is to perform functional tests to assess whether the variants affect protein function. We have used this strategy to characterise variants identified in the TSC1 and TSC2 genes in individuals with, or suspected of having, Tuberous Sclerosis Complex (TSC). Here we present an overview of our functional studies on 45 TSC1 and 107 TSC2 variants. Using a standardised protocol we classified 16 TSC1 variants and 70 TSC2 variants as pathogenic. In addition we identified 8 putative splice site mutations (5 TSC1 and 3 TSC2). The remaining 24 TSC1 and 34 TSC2 variants were classified as probably neutral.
