Medical Genetics in the Clinic Flashcards
<p>What do most genetic referals related to?</p>
<p>Cancer, and then cardiac</p>
<p>What does the clinical assessment in a genetics clinic involve?</p>
<p>History</p>
<p>Pedigree</p>
<p>Clinical examination</p>
<p>Genetics test</p>
<p>Synthesis</p>
<p>What are examples of genetic tests?</p>
<p>Microarray</p>
<p>Gene tests such as mutations, single gene screen, gene panel</p>
<p>What is a microarray?</p>
<p>Set of DNA sequences representing the entire set of genes of an organism</p>
<p>What does genetic counselling let patients known about?</p>
<p>Risks of passing on disorders</p>
<p>What is involved in genetic counselling?</p>
<p>Clinical geneticist</p>
<p>Genetic counsellor</p>
<p>Hospital doctor</p>
<p>GP</p>
<p>Nurse</p>
<p>What has happened to the molecular genetics workload over the last 20 years?</p>
<p>Drastically increased</p>
<p>What technology has made genetics easier?</p>
<p>Automated sequencing</p>
<p>What are advantages of automated sequencing?</p>
<p>Costs have fallen</p>
<p>Time taken to interpret data has reduced</p>
<p>What are disadvantages of automated sequencing?</p>
<p>Interpretation of variants needs skilled scientists</p>
<p>Confirmation of results is still required</p>
<p>How can we decide if a sequence variant is disease causing?</p>
<p>In silico prediction of variant impact</p>
<p>Massive international online databases</p>
<p>What does in silico mean?</p>
<p>On a computer</p>
<p>What are some questions that helps in silico predictions decide if a sequence variant is disease causing?</p>
<p>Does the amino acid change</p>
<p>Is the amino acid of different charge</p>
<p>Stop codon or splicing</p>
<p>Reported before associated with disease</p>
<p>What are the gene variant classifications?</p>
<p>Class 5 (pathogenic)</p>
<p>Class 4 (likely pathogenic)</p>
<p>Class 3 (variant of uncertain significance)</p>
<p>Class 2 (likely benign)</p>
<p>Class 1 (benign)</p>
<p></p>
<p>What happens with the more sequencing that you do?</p>
<p>The more variants you find</p>
<p>More false positives</p>
