A long white line running down a fingernail could be a sign of a rare genetic condition that increases the risk of kidney, skin, eye, and lung cancer, according to new research. Scientists at the National Institutes of Health (NIH) have found that 88% of people with this genetic disorder have abnormal nail markings, including a thin white line running the length of the nail. The condition is believed to run in fewer than 100 American families.

What You'll Learn
- A long white line on a fingernail could indicate a higher risk of kidney cancer
- A rare genetic condition can cause abnormal nail markings and increase the risk of cancer
- A thickened area of skin under the nail, along with a white band, is consistent with onychopapilloma, a benign tumour
- Onychopapilloma affects the production and distribution of keratin, the protein that makes up the nail
- The uvea, which includes the iris, accounts for about 5% of melanoma cases in the US
A long white line on a fingernail could indicate a higher risk of kidney cancer
The most distinctive finding of this disorder is a small, thickened area of skin under the nail, along with a white band running down the nail, which is consistent with onychopapilloma, a type of benign tumour. The tumour is believed to affect the production and distribution of keratin, the type of protein that makes up the nail. The white lines represent higher levels of keratinisation, or areas where the nail has been lifted or distorted by the tumour underneath.

Onychopapilloma is not cancerous, but it is important to be aware of any changes to your nails as they can indicate other health issues. For example, new research suggests that faint lines on your fingernails could indicate a rare genetic condition that puts you at risk of cancer. Scientists at the National Institutes of Health (NIH) have discovered that 88% of people with a rare genetic disorder that can lead to cancer have abnormal nail markings, including a thin white line running the length of the nail. This genetic disorder is believed to run in fewer than 100 American families and increases the odds of a rare type of eye cancer, as well as lung, skin and kidney cancer.

Onychopapilloma affects the production and distribution of keratin, the protein that makes up the nail
A long white line on your fingernail could indicate that you are at a much higher risk of developing kidney cancer. Research suggests that 88% of people with a rare genetic disorder that can lead to cancer have abnormal nail markings, including a thin white line running the length of the nail. This genetic disorder is believed to run in fewer than 100 American families and increases the odds of a rare type of eye cancer, as well as lung, skin and kidney cancer.

Onychopapilloma affects the production and distribution of keratin, the protein that makes up the nail. The white lines represent higher levels of keratinisation, or areas where the nail has been lifted or distorted by the tumour underneath.
Alexandra Lebensohn, a National Cancer Institute researcher who helped conduct the study, said: "When asked about nail health during a baseline genetic assessment, a very astute patient reported that he had noticed subtle changes in his nail. His comment prompted us to systematically evaluate other participants for nail changes and uncover this new finding."
If you notice any changes to your nails, it is important to consult a doctor or healthcare professional as soon as possible. They will be able to assess your nail health and determine if any further tests or treatments are necessary.

A line going down a fingernail could be a sign of a rare genetic condition that puts you at risk of kidney, skin, and eye cancers. A study by the National Cancer Institute found that 88% of people with a rare genetic disorder that can lead to cancer have abnormal nail markings, including a thin white line running the length of the nail. This is caused by higher levels of keratinisation, or areas where the nail has been lifted or distorted by a tumour underneath.
The uvea, which includes the iris, accounts for only about 5% of melanoma cases in the US. Uveal melanoma is a rare form of melanoma, sometimes called ocular melanoma, that affects the uvea, the middle layer of the eye that contains blood vessels, pigment cells (melanocytes), and provides nutrients and oxygen to the retina. It is a serious condition that requires prompt medical attention. If undiagnosed, it can be aggressive and spread to other parts of the body, such as the liver, lungs, brain, kidney, and bones. The most common site for uveal melanoma is the choroid, followed by the ciliary body and iris.
