Also known as: Bloom-Torre-Machacek syndrome; Congenital Telangiectatic Erythema
Bloom syndrome is a rare genetic condition that causes short stature, sensitive skin and an increased risk of cancer. Typically those affected have a narrow face and redness of the skin of the face, which is aggravated by sunlight. Respiratory tract and ear infections are common, sometimes related to gastro-oesophageal reflux (acid and stomach contents flowing back into the gullet). Men and women experience reduced fertility and also have an increased risk of malignant tumours, which invade other parts of the body. There is also an increased risk of diabetes mellitus. Bloom syndrome is caused by faults in the BLM gene on chromosome 15. A diagnosis can be made by a chromosome test to look at the chromosome. Management of the condition involves regular monitoring to identify any cancers for treatment. X-rays and other environmental exposure to substances that cause DNA damage should be avoided. Prompt treatment of infections with antibiotics is important as is treatment for reflux, which may help to prevent some of the infections. The condition is inherited in an autosomal recessive manner. Affected families should be referred to a genetics centre for information and support.
