Disclaimer

Where discrepancies have arisen between reported sequences and those stored in the databases, the original authors have been contacted where possible, and necessary amendments to published sequences have been incorporated. Future sequencing may identify errors and the Nomenclature Committees would welcome any evidence that helps to maintain the accuracy of the database. We therefore make no warranties regarding the correctness of the data, and disclaim liability for damages resulting from its use. We cannot provide unrestricted permission regarding the use of the data, as some data may be covered by patents or other rights.
