Bloom syndrome is an inherited disorder characterized by short stature, a skin rash that develops after exposure to the sun, and a greatly increased risk of cancer.
People with Bloom syndrome are usually smaller than 97 percent of the population in both height and weight from birth, and they rarely exceed 5 feet tall in adulthood.
Affected individuals have skin that is sensitive to sun exposure, and they usually develop a butterfly-shaped patch of reddened skin across the nose and cheeks. A skin rash can also appear on other areas that are typically exposed to the sun, such as the back of the hands and the forearms. Small clusters of enlarged blood vessels (telangiectases) often appear in the rash; telangiectases can also occur in the eyes. Other skin features include patches of skin that are lighter or darker than the surrounding areas (hypopigmentation or hyperpigmentation respectively). These patches appear on areas of the skin that are not exposed to the sun, and their development is not related to the rashes.
People with Bloom syndrome have an increased risk of cancer. They can develop any type of cancer, but the cancers arise earlier in life than they do in the general population, and affected individuals often develop more than one type of cancer.
Individuals with Bloom syndrome have a high-pitched voice and distinctive facial features including a long, narrow face; a small lower jaw; and prominent nose and ears. Other features can include learning disabilities, an increased risk of diabetes, chronic obstructive pulmonary disease (COPD), and mild immune system abnormalities leading to recurrent infections of the upper respiratory tract, ears, and lungs during infancy. Men with Bloom syndrome usually do not produce sperm and as a result are unable to father children (infertile). Women with the disorder generally have reduced fertility and experience menopause at an earlier age than usual.
MalaCards based summary : Bloom Syndrome, also known as bloom-torre-machacek syndrome, is related to hereditary breast ovarian cancer syndrome and wilms tumor predisposition. An important gene associated with Bloom Syndrome is BLM (BLM RecQ Like Helicase), and among its related pathways/superpathways are Homologous recombination and Fanconi anemia pathway. The drug Cola has been mentioned in the context of this disorder. Affiliated tissues include skin, lung and eye, and related phenotypes are intrauterine growth retardation and narrow face Disease Ontology : 12 A syndrome characterized by sun sensitivity, short stature, predisposition to the development of cancer and genomic instability. NIH Rare Diseases : 52 Bloom syndrome is a disorder characterized by a significantly increased risk of cancer and various other features. Signs and symptoms include short stature ; sun-sensitive skin changes on the face, hands and/or arms; a high-pitched voice; and distinctive facial features including a long, narrow face, small lower jaw, large nose and prominent ears. Some affected individuals may also have learning disabilities; an increased risk of diabetes; chronic obstructive pulmonary disease (COPD); and recurrent infections of the upper respiratory tract, ears, and lungs during infancy. Cancers may include any of those found in the general population, but develop much earlier in life in affected individuals. It is caused by mutations in the BLM gene and is inherited in an autosomal recessive manner. Treatment is generally symptomatic and supportive. OMIM : 56 Bloom syndrome is an autosomal recessive disorder characterized by proportionate pre- and postnatal growth deficiency; sun-sensitive, telangiectatic, hypo- and hyperpigmented skin; predisposition to malignancy; and chromosomal instability. (210900) KEGG : 36 Bloom syndrome is a rare autosomal recessive genetic disorder due to mutation in BLM (RecQ protein-like 3). This disease is characterized by dwarfism, photosensitivity, immunodeficiency and a high predisposition to various types of cancer. The function of BLM as a helicase and its role during the regulation of homologous recombination (HR) is well characterized. Recently, the role of BLM as a DNA damage sensor has been revealed. UniProtKB/Swiss-Prot : 73 Bloom syndrome: An autosomal recessive disorder. It is characterized by proportionate pre- and postnatal growth deficiency, sun-sensitive telangiectatic hypo- and hyperpigmented skin, predisposition to malignancy, and chromosomal instability.
