Influence of family history on penetrance of hereditary cancers in a population setting.
Leigh Jackson et al. EClinicalMedicine 2023 11 102159

From the abstract: "Women with a pathogenic BRCA1 or BRCA2 variant had an increased risk of breast cancer that was higher in those with a first-degree family history (relative hazard 10.3 and 7.8, respectively) than those without (7.2 and 4.7). Penetrance to age 60 was also higher in those with a family history (44.7%, CI 32.2-59.3 and 24.1%, CI 17.5-32.6) versus those without (22.8%, CI 15.9-32.0 and 17.9%, CI 13.8-23.0). A similar pattern was seen in Lynch syndrome: individuals with a pathogenic MLH1, MSH2 or MSH6 variant had an increased risk of colorectal cancer that was significantly higher in those with a family history (relative hazard 35.6, 48.0 and 9.9) "

Association Between a First-Degree Family History and Self-Reported Personal History of Obesity, Diabetes, and Heart and Blood Conditions: Results From the All of Us Research Program.
Danielle Rasooly et al. J Am Heart Assoc 2023 11 e030779

From the abstract: "We assessed the association between a self-reported family history of ODHBs and their risk in the adult population (age =20 years) of the AoU (All of Us) Research Program, a longitudinal cohort study of diverse participants across the United States. We conducted a family history-wide association study to systematically assess the association of a first-degree family history of 15 ODHBs in AoU. We use the FamWAS method to estimate 225 familial associations among 15 ODHBs. The results include overlapping associations between family history of different types of cardiometabolic conditions (such as type 2 diabetes and coronary artery disease), and their risk factors (obesity, hypertension), where adults with a family history of 1 ODHB exhibited 1.1 to 5.6 times (1.5, on average) the odds of having a different ODHB.

How to Talk to Your Family About Their Heart Health History Even if you’re not super close to your relatives, you’ve got options.
K Miller, Self, September 2023

From the website: "If someone in your bio family has heart problems, don’t freak out: It doesn’t mean that you’ll automatically develop them too. Yes, that does increase your risk of developing an issue—but there are loads of other factors that might be meaningful, and this genetic link is just one part of a fuller picture. Bring any information you turn up to a primary care physician first (if you’re not already seeing a specialist): Depending on what you share, your PCP might refer you to a cardiologist who can take a closer look at your overall health, as well as any symptoms that could be indicative of a larger cardiovascular issue.

Are You Up to Date on Your Preventive Care?
CDC, July 2023 Brand

Family health history is a record of the diseases and health conditions in your family. You and your family members share genes. You may also have behaviors in common, like what you do for physical activity and what you like to eat. You may live in the same area and come into contact with similar harmful things in the environment. Family history includes all of these factors, any of which can affect your health. If you have a family history of a chronic disease, like cancer, heart disease, diabetes, or osteoporosis, you’re more likely to get that disease yourself.
