Before any study specific procedure or screening is done, the subject or legally acceptable representative must give informed consent for participation in the study (see Section 12.2). Before buccal smears and blood samples are taken for genetic testing, the subject or legally acceptable representative must give informed consent for use of those samples for genetic testing (see Section 12.2).
