About This Presentation

Description : Check out this medical PowerPoint presentation titled "Genetics".
This medical PowerPoint presentation talks about genetics, the branch of biology that studies genes, heredity, and variation in living organisms. It involves the study of DNA, the molecule that carries genetic information, and how genes are passed down from generation to generation. Genetics plays a critical role in determining an organisms physical traits, such as eye color and height, as well as its susceptibility to certain diseases. Genetic research is also important in fields such as agriculture, evolutionary biology, and biotechnology. Techniques such as genetic engineering and gene editing allow scientists to manipulate the genetic makeup of organisms, potentially leading to advances in medicine and agriculture.

Top 5 Reasons to Know Your Family History 5. Family recipes should be kept secret — family medical history should not. 4. Knowing your risk might save your life. 3. It’s free and you don’t have to leave home. 2. It’s a priceless gift to leave to your children. 1. Because every family has a story, but not every family has YOUR story. https://www.yahoo.com/health/10-reasons-you-should-dig-into-your-family-medical-118232923367.html

Cancer and Genetics
Slide 13-

Fortune Cookie Tip #1 Family history was the first genetic test
Slide 14-

Clues:Genetic Risk for Cancer YOUNG Breast <45, Colon <50 RARE Examples include Ovarian, Male Breast, Pancreatic MULTIPLE Two or more different cancers in the same person FAMILY Two or more family members with the same or related types of cancer. Breast/Ovary. Breast/Thyroid/Uterine. Breast/Sarcoma/Brain
Slide 15-

Colon, 72 Sporadic Family History Risk for cancer is AVERAGE
Slide 16-

Familial Family History Prostate, 75 Lung, 65 coal miner Stomach, 55 H. pylori Liver, 50 alcohol abuse Cervix HPV, smoker Lung, 58 smoker Basal Cell sun exposure Risk for cancer is MODERATE
Slide 17-

Hereditary Family History Breast, 55 Ovarian, 44 Breast, 34 Prostate, 59 Breast, 50 Risk for cancer is HIGH
Slide 18-

Fortune Cookie Tip #2 Don’t forget to look at both sides of the family!
Slide 19-

Why would I want to know? Possible risk of another, new cancer Risks to your children Risks to other family members Screening and prevention are often available and may save a life

Cancer Risks with HBOC
Slide 26-

What Can You Do? Increased screening Start Earlier 25yo for breast screening More Often Alternating imaging every 6 months More Aggressive Mammogram + Breast MRI Prevention Medication Tamoxifen (breast cancer risk) Birth control pills (ovarian cancer risk) Surgery Risk reducing mastectomy Salpingo-oophorectomy (removal of ovaries and fallopian tubes)

Multi-Gene (NGS) Panels Genetic tests to look at dozens of genes related to cancer Similar cost and turn around time as gene specific testing Higher risk of uncertain results
Slide 32-

NGS Panels- Breast Walsh et. al. 2013 (ASHG Platform Presentation) 800 families with negative BRCA1/2 testing 206 tested positive with NGS BROCA panel (26%) Of the 26% with a new positive results 39% (80/206) had BRCA1/2 mutations 37% carried mutations in CHEK2, PALB2, or TP53 20% carried mutations in 10 less characterized genes

NGS Test Result Positive for a gene mutation CHEK2 Variants of Uncertain Significance BRCA 2 STK11
Slide 36-

Fortune Cookie Tip #4 Sometimes, in our quest for answers, we end up with more questions
Slide 37-

Moderate Risk Genes Cancer risks may not be very high How high does risk need to be before we pursue surgery or medications? Cancer risks may be unclear How do we make medical decisions when we don’t know the risks? We’re still learning The recommendations you get today may be different in 5 years

Rates of Uncertain Variants Eggington et. al. Current Variant of Uncertain Significance Rates in BRCA1/2 and Lynch Syndrome Testing (MLH1, MSH2, MSH6, PMS2, EPCAM), March 2012, ACMG Poster Presentation.
Slide 42-

Isn’t it just a blood test? Positive results with limited information Inconclusive results Results that don’t “fit” Worry/anxiety
Slide 43-

Consider This… Unclear results Limited data Limited usefulness Changes in technology BENEFITS Anxiety/ distress Privacy Appropriate follow-up? Clarification of risk Guidance for medical management Information for family RISKS LIMITATIONS
