New research involving the DNA of 200,000 U.S. veterans suggests that there really is such a thing as a "worry gene."

Researchers have identified six genetic variants linked to anxiety -- a discovery that may help explain why anxiety and depression often go hand in hand.

"This is the richest set of results for the genetic basis of anxiety to date," said study co-lead author...

"Designer babies" aren't going to be a reality anytime soon, researchers say.

Concerns about genetically altering embryos to have desired traits have been around nearly as long as in vitro fertilization (IVF) and the technology to screen embryos have existed.

But while recent live births resulting from embryonic CRISPR gene editing have re-focused attention on the issue, the...

Parents usually know their child better than anyone, and if a parent suspects something is wrong, it probably is.

That was the case for Dan and Laura Wallenberg from Columbus, Ohio. EV Wallenberg was just 5 months old when they noticed that their daughter wasn't eating normally. They scheduled a visit with her pediatrician.

"I knew something wasn't right. But the doctor ju...

A three-drug combo that significantly improves lung function in cystic fibrosis patients could benefit 90% of people with the life-threatening disease, a new study suggests.

It included patients with a single copy of the most common genetic mutation for the disease.

Results of the international phase 3 clinical trial led the U.S. Food and Drug Administration to approve ...

A new drug to treat most cystic fibrosis patients has been approved by the U.S. Food and Drug Administration.

Trikafta (elexacaftor/ivacaftor/tezacaftor) is the first triple combination therapy available to treat patients with the most common cystic fibrosis mutation. Its list price is $311,000 a year, same as one of the maker's earlier treatments for the genetic disease.

Most people expect some risk in activities like mountain biking or rollerblading, but few would expect to end up in the emergency room with a broken thigh bone from doing a squat.

That's exactly what happened to Rachael Jones, 39, who was just trying to stay in shape, despite having a lifelong genetic illness.

The broken femur wasn't her first broken bone -- and it may not...

Mutations in two genes -- BRCA1 and BRCA2 -- are known to significantly increase the risk of breast cancer, but experts have long debated which women should be tested for them.

New recommendations from the U.S. Preventive Services Task Force (USPSTF) may help clarify who can benefit most from a risk assessment test. Now, if a woman has a high risk, the task force is recommending that...

Too much white bread and pasta fed to at-risk kids under age 5 could increase their odds of developing celiac disease, a new international study has concluded.

Every extra daily gram of gluten a young child eats increases their risk of celiac disease, if they are genetically predisposed to it, researchers found.

For example, eating an extra half-slice of white bread every day at...

Children with birth defects may be at increased risk for childhood cancer, a new study finds.

Researchers analyzed data from more than 10 million children born in Texas, Arkansas, Michigan and North Carolina between 1992 and 2013.

Compared to children without a birth defect, those with genetic defects were almost 12 times more likely to develop cancer by age 18. Those whose ...

Breast MRI screening is a good way to detect small tumors, but it's unclear how much it benefits women with a history of breast cancer, a new study finds.

Right now, experts recommend that breast cancer survivors have yearly mammograms to help catch any recurrences early. An unresolved question is whether adding breast MRI to that screening is beneficial.

In the new study, r...

Some folks are more prone to fainting than others, and the reason might lie in their DNA.

Danish researchers who analyzed millions of gene variants in DNA of 400,000 people have zeroed in on a gene that increases a person's risk for fainting.

It's believed that 20% to 30% of people faint at least once in their lifetime, often due to heat, dehydration or anxiety. But ...

It has long been known that lifestyle affects a person's risk of developing type 2 diabetes. Now, researchers report that they have identified rare variants of four genes that may also play a part.

When couples experience recurrent pregnancy loss, it's natural for them to want to know why. Now, a new study suggests that sperm DNA damage could be a factor.

Recurrent pregnancy loss is defined as the consecutive loss of three or more pregnancies before 20 weeks' gestation. It affects up to 2 percent of couples and, in many cases, it is difficult to ident...

People whose high cholesterol is resistant to treatment with statin drugs may soon have a new treatment option.

This new class of drugs helps block synthesis of artery-clogging cholesterol, researchers explained. The drugs target an enzyme called ATP citrate lyase (ACL), part of the production pathway for "bad" LDL cholesterol in the body.

In the new trial, bempedoic acid, a pil...

It's one of the toughest cancers to beat. But new research suggests that identifying the genetics of pancreatic cancer in individual patients could boost survival for some.

The five-year survival rate for pancreatic cancer patients is less than 9 percent. One reason this cancer is so deadly is that many patients are diagnosed at a late stage and often with inoperable tumors.

Women who have specific mutations in genes known as BRCA are at increased risk for breast and ovarian cancers. Now, an influential expert panel reaffirms that certain women should be screened for the genes.

The draft recommendation comes from the U.S. Preventive Services Task Force, whose advisories often guide physician practice and insurance coverage. The guidelines -- which restate...

The most potent drug available for Parkinson's disease, levodopa, treats symptoms of the disease but does nothing to either ease or increase its still-mysterious underlying causes, a new clinical trial has concluded.

Doctors often delay prescribing levodopa, or L-dopa, to Parkinson's patients for fear that the drug might have toxic effects that produce jerky involuntary body movements o...

The most common genetic disorder among northern Europeans -- called hemochromatosis -- occurs more often than previously thought, according to a new study.

The researchers also found that people with the condition often develop serious health problems.

People with hemochromatosis -- a build-up of iron in the body that can damage the liver, heart and other organs -- have two ...

Two of every five common diseases are at least partially influenced by a person's genetics, the largest U.S. study of twins ever conducted finds.

Nearly 40 percent of 560 different diseases have a genetic component, while 25 percent are driven by environmental factors shared by twins who are growing up in the same household, the researchers reported.

Brain disorders were mos...

Lots of Americans will unwrap a scarf or sweater this holiday season. But a growing number will receive a gift that's potentially life-changing: an at-home genetic testing kit.

Home DNA testing yields clues to ancestry and, potentially, genetic risk for medical conditions. But there are a number of things you need to know before you use one of these kits, the Alzheimer's Foundation of...

Medical science has made tremendous advances in "personalized medicine" -- drugs that fight cancer and other diseases by boosting the immune system or targeting specific genetic traits.

Former U.S. President Jimmy Carter benefited from one of these drugs, Keytruda (pembrolizumab), which successfully beat back his brain cancer by ramping up his immune system.

But the American...

Kids with summer birthdays, especially those who spend long hours playing on smartphones and tablets, might be at greater risk for vision problems, a new study suggests.

Nearsightedness, also called myopia, is on the rise worldwide. It's what eye doctors call a refractive error, meaning the eyes can't focus light properly. The result: Close objects look clear; distant ones, fuzzy.

...

It's not always easy -- even for doctors -- to tell if someone has type 1 or type 2 diabetes when they're diagnosed as an adult.

And a new study finds mistakes are common.

That's what happened to British Prime Minister Theresa May when she was diagnosed with type 2 diabetes in 2012. She was in her 50s at the time. Despite having all of the symptoms common to type 1 diabetes...

Only a small percentage of Americans have had their DNA analyzed -- but many are tempted to try it, according to new research.

For the study, University of Michigan researchers surveyed nearly 1,000 adults aged 50 to 64. While curious about their ancestry or health risks, the majority said they fear they'll worry excessively if they learn they have genetic links to progressive diseas...

Most people carrying genes that put them at risk for cancer don't realize it, new research suggests.

Genetic screenings of more than 50,000 people found that more than 80 percent of those who carry a known gene variant for breast, ovarian, prostate or pancreatic cancer were unaware of their risk.

Researchers noted that most people carrying cancer-associated variants in the B...

Testing for gene mutations linked to breast and ovarian cancer is rare among some Medicare patients who have the cancers and qualify for such tests, a new study finds.

Researchers analyzed data from 12 southeastern states between 2000 and 2014. Only 8 percent of 92 women who met Medicare criteria for BRCA1 and BRCA2 gene testing received it within five years of their cancer diagnosis,...

High levels of exposure to the insecticide DDT in women seems to more than double the risk of autism in their children, new research suggests.

The study looked for a link between the development of autism and two common environmental chemicals -- DDT and PCBs. PCBs are chemicals that were used in many products, especially transformers and electrical equipment. In this study, they wer...

A new type of genetic analysis could identify millions of Americans at high risk for five serious and common diseases, researchers report.

People who have frequent recurrences of a common skin cancer may be at increased risk of a range of other cancers, a new study suggests.

Researchers found the heightened risk among patients who'd had many bouts of basal cell carcinoma (BCC) -- a highly treatable form of skin cancer diagnosed in over 3 million Americans each year.

Patients who'd developed at least six BCCs ov...

Many lives could be saved if relatives of patients with aortic diseases underwent routine screening and genetic testing, a new study suggests.

Aneurysms, tears in the lining called dissections and other types of thoracic aortic disease (TAD) are often undetected until they become life-threatening emergencies. At that point, the risk of death is about 80 percent.

The aorta i...

Scientists may have found a way to slip a special type of disease-fighting virus past the guard of the body's immune system and into targeted cells where it can do its intended work, according to new research presented Tuesday at a scientific conference.

The body naturally reacts to viruses by fighting them off with antibodies that neutralize them and help the body develop an immuni...

British researchers are zeroing in on the genes that they believe are responsible for early onset Alzheimer's disease in people with Down syndrome.
