NIH Links Nail Abnormalities to a Rare Cancer Syndrome

Researchers at the National Institutes of Health (NIH) have made a groundbreaking discovery, establishing a link between benign nail abnormalities and BAP1 tumor predisposition syndrome. This rare inherited disorder significantly escalates the risk of cancer. Published in JAMA Dermatology, these findings could potentially transform the field of early cancer detection.

The breakthrough was made during a screening study when a patient reported subtle changes in their nails. The scientists discovered that a staggering 88% of study participants aged 30 and above with BAP1 syndrome had onychopapilloma tumors affecting multiple nails. This is a condition that typically affects only a single nail in the general population.

BAP1 tumor predisposition syndrome heightens the risk of developing cancerous tumors in the skin, eyes, kidneys, and the lining of the chest/abdomen. The nail condition manifests as colored bands (usually white or red) along the length of the nail, accompanied by thickening of the nail and nail bed.

“This finding is rarely seen in the general population, and we believe the presence of nail changes that suggest onychopapillomas on multiple nails should prompt consideration of BAP1 syndrome diagnosis,” said Dr. Edward Cowen, head of Dermatology Consultation Services at NIH.

Researchers strongly recommend nail screening for patients with a personal or family history of melanoma or other BAP1-associated malignancies.
