The TSC2 gene homepage
The curator’s expert opinion on the classification of a variant, can be found in the SUMMARY record. Regarding the classification, please note that where there are several records of the same variant, the classification of that variant may differ depending on the submitter’s conclusion.

| Notes |
The Purpose of the Database is to provide information to help diagnostic laboratories and clinicians interpret the results of genetic testing for tuberous sclerosis (TSC). It can be difficult to decide whether a change found in the DNA of one of the TSC genes is the change that is causing TSC or a harmless variation which can be ignored. The database allows scientists and clinicians to check whether the change has been reported by other laboratories and whether it is thought to be a cause of TSC or a normal variation. All the information in the database is anonymous and care has been taken to exclude any information which might lead to patients being identified. In supporting genetic testing for TSC the database provides a valuable service for patients and their families.
Variants listed here are collated from The Cardiff-Rotterdam Tuberous Sclerosis Mutation Database, David Kwiatkowski's Tuberous Sclerosis Project, publications and submissions to the database. Should you notice that there are variants not in the database or that there are errors, please inform us.
We gratefully acknowledge the key role of Sue Povey in establishing the TSC databases and their curation (2005-2019). She always gave thoughtful and careful consideration to the classification of each variant because there was always a patient involved.
The curation of this database was supported (2005-2020) by the  and the  .
The database is kindly hosted by Global Variome, and the TSC curators are based at University College London.
Uncurated Data - If you have a Clinical problem with a variant that is not visible in the database, please note that some variants are not publicly viewable, so do contact us.
