BAP1 tumour predisposition syndrome is an inherited disorder that increases the risk of a variety of cancerous (malignant) and noncancerous (benign) tumours, most commonly certain types of tumours that occur in the skin, eyes, kidneys, and the tissue that lines the chest, abdomen, and the outer surface of the internal organs (the mesothelium). Affected individuals can develop one or more types of tumour, and affected members of the same family can have different types.
Description
BAP1 tumour predisposition syndrome is an inherited disorder that increases the risk of a variety of cancerous (malignant) and noncancerous (benign) tumours, most commonly certain types of tumours that occur in the skin, eyes, kidneys, and the tissue that lines the chest, abdomen, and the outer surface of the internal organs (the mesothelium). Affected individuals can develop one or more types of tumour, and affected members of the same family can have different types.
Some people with BAP1 tumour predisposition syndrome develop growths in the skin known as atypical Spitz tumours. People with this syndrome may have more than one of these tumours, and they can have dozens. Atypical Spitz tumours are generally considered benign, although it is unclear if they can become cancerous. Skin cancers are also associated with BAP1 tumour predisposition syndrome, including cutaneous melanoma and basal cell carcinoma.
A type of eye cancer called uveal melanoma is the most common cancerous tumour in BAP1 tumour predisposition syndrome. Although uveal melanoma does not usually cause any symptoms, some people with this type of cancer have blurred vision; small, moving dots (floaters) or flashes of light in their vision; headaches; or a visible dark spot on the eye.
People with BAP1 tumour predisposition syndrome are at risk of developing malignant mesothelioma, which is cancer of the mesothelium. When associated with BAP1 tumour predisposition syndrome, malignant mesothelioma most often occurs in the membrane that lines the abdomen and covers the abdominal organs (the peritoneum). It less commonly occurs in the outer covering of the lungs (the pleura).
A form of kidney cancer called clear cell renal cell carcinoma is also associated with the condition. Researchers are still determining whether other forms of cancer are linked to BAP1 tumour predisposition syndrome.
When they occur in people with BAP1 tumour predisposition syndrome, cancers tend to arise at a younger age and are often more aggressive than cancers in the general population. The cancerous tumours in BAP1 tumour predisposition syndrome tend to spread (metastasize) to other parts of the body. Survival of affected individuals with this syndrome is usually shorter than in other people who have one of these cancers. However, individuals with malignant mesothelioma as part of the BAP1 tumour predisposition syndrome appear to survive longer than those who have the cancer without the syndrome.
