Summaries for Bloom Syndrome

About this section
NIH Rare Diseases : 54 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.

MalaCards based summary : Bloom Syndrome, also known as bloom-torre-machacek syndrome, is related to adermatoglyphia and fanconi anemia, complementation group a. 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. Affiliated tissues include skin, lung and bone, and related phenotypes are malar flattening and recurrent respiratory infections

Disease Ontology : 12 An autosomal recessive disease characterized by sun sensitivity, short stature, predisposition to the development of cancer and genomic instability.

Genetics Home Reference : 26 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.

OMIM : 58 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)

UniProtKB/Swiss-Prot : 76 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.
