Nonsyndromic Hearing Loss and Deafness, DFNB1
What is DFNB1? DFNB1 is an inherited condition characterized by mild to profound hearing loss that is typically present from birth. In most cases, a person must have two variants in the GJB2 gene in order to have this condition. People with just one variant in the GJB2 gene are called carriers. They’re not expected…

Genetics and Weight
Do genetic factors influence your weight? Yes! The fit of your jeans is affected at least in part by your genes. Lots of research has shown that genetics not only impacts how much we weigh but also how much diet and exercise may make a difference. Our weight is the product of genetics, lifestyle, and…

Widow’s Peak Hairline & Genetics
How it works It’s a common misconception that a particular dominant gene causes a widow’s peak. Like other traits that influence hair growth, various genes work together to help determine the shape of our hairlines. Some researchers believe that hair patterns are heritable, so a close relative with a widow’s peak may increase your chances…

Unibrows & Genetics
How it works No one is quite sure why our eyebrow hairs grow in particular patterns—or the reason why some people have unibrows. But initial findings offer some clues. The genetic link 23andMe researchers have identified more than 50 genetic variants associated with having a unibrow. Two of those genetic variants are in or near…

Toe Length Ratio & Genetics
How it works Some people have a longer big toe, while others have longer second toes. Toe length ratio may be influenced by the amount of testosterone and estrogen present in the womb during early pregnancy. The genetic link 23andMe looks at 35 places in your DNA that can influence your toe length ratio, along…

Sweet vs. Salty Taste Preferences & Genetics
How it works With each bite-or sip-our taste buds send signals to a brain area called the “primary gustatory cortex” that helps identify taste. Another area, the “orbitofrontal cortex”, helps judge whether you like these tastes. Other brain areas help us decide whether we want to keep munching or we’ve had enough. The genetic link…

Stretch Marks & Genetics
How it works Stretch marks are a type of scarring that look like stripes on the skin and are commonly found on the hips, thighs, and abdomen. They often develop when the skin stretches during a quick period of growth, like during adolescence, pregnancy, or rapid weight gain. The genetic link 23andMe scientists identified 544…
