ENGLISH DIVISION Faculty of Medicine, III YEAR OF STUDY (6th semester), February − June 2013 y. lectures 20 hrs tutorials and seminars 40 hrs Final one−choice test at the end of the semester. General Rules and Regulations for Completing Clinical Genetics Course Course content Clinical tutorials Laboratory seminars Lectures List of textbooks GENERAL RULES AND REGULATIONS FOR COMPLETING CLINICAL GENETICS COURSE This course comprises a series of tutorials, laboratory seminars and lectures. The tutorials will mostly concentrate on genetic counselling in various clinical settings, the laboratory seminars will feature presentations of laboratory methods and techniques used in diagnosing genetic diseases. The lectures will introduce the basic concepts of mutagenesis and molecular biology of cancer. To pass the course it is necessary to attain a pass on the continuous assessment and to attain a positive grade on the end-of-course examination. For the continuous assessment mark, students will be assessed throughout the course, in the form of regular review by their course tutors (that includes two written test). There will be an examination at the end of the semester based upon the whole course. If a student should fail on the continuous assessment he/she will be not allowed to sit the examination. The student will get a chance to write a final test based on the tutorial and seminar material. Only then the student will be offered the opportunity to take the examination. Attendance at the tutorials and laboratory seminars is compulsory. Students can miss one seminar or a tutorial without any repercussions. If the student misses more than one, he/she should report to the Dean’s Office with an appropriate document stating the reasons of absence. A copy should be presented to the tutor. There will be a chance to discuss the omitted material at the end of the semester. Otherwise the student will fail on the continuous assessment. Students should prepare for each of the tutorials and laboratory seminars. The student should be ready to discuss the clinical case and know the theory behind it. 1 COURSE CONTENT Laboratory seminars: 1.
