"Scientists have developed a new genetic test for Alzheimer’s risk that can be used to predict the age at which a person will develop the disease.

A high score on the test, which is based on 31 genetic markers, can translate to being diagnosed many years earlier than those with a low-risk genetic profile, the study found. Those ranked in the top 10% in terms of risk were more than three times as likely to develop Alzheimer’s during the course of the study, and did so more than a decade before those who ranked in the lowest 10%."

"while genetic makeup can influence the chances of developing dementia, a healthy diet, regular physical activity and remaining mentally active can also drive down the risk. “Genetics is only part of the story and we know that lifestyle factors also influence our risk of developing Alzheimer’s,” she said. “The best current evidence points to habits we can all adopt to help lower our risk and indicates that what’s good for your heart is also good for the brain.”"

Should You Get Tested for the Breast Cancer Genes? - Scientific American

"The mostly common involved and most familiar breast cancer genes are the BRCA-1 and BRCA-2 genes. This sort of gene testing can be performed on blood, saliva, or even cheek swabbing.  The challenge? Hundreds of genes involving these two mutations have been discovered. Therefore, obtaining a complete test for all involved possibilities can cost up to 4,000 dollars. If patients meet certain criteria, however, insurance may cover up to 90% of the testing cost. What may be less costly and more simple, however, is if you already have an identified gene in another relative, in which testing can be more targeted and therefore much less costly."
