Bloom syndrome

(redirected from Bloom's syndrome)

Bloom syn·drome

(blōm), [MIM*210900]
congenital telangiectatic erythema, primarily in butterfly distribution, of the face and occasionally of the hands and forearms, with sun sensitivity of skin lesions and dwarfism with normal body proportions except for a narrow face and dolichocephalic skull; chromosomes are excessively unstable and there is a predisposition to malignancy; autosomal recessive inheritance, caused by mutation in the Bloom syndrome gene (BLM) on chromosome 15q.

Bloom syndrome

(blo͞om) or

Bloom's syndrome

(blo͞omz)
n.
A rare autosomal recessive condition characterized by small stature, photosensitive skin with facial telangiectasia and erythema, and a predisposition to various cancers.

Bloom syndrome

A Jewish genetic disease of early onset.
 
Clinical findings
Pre- and postnatal growth deficiency, photosensitivity, benign and malignant tumours in childhood, male sterility, scattered skin lesions (facial telangiectasias, abnormal pigmentation), death in early adulthood usually due to cancer.
 
Molecular pathology
BLM mutation results in a deficiency of Bloom helicase, leading to mitotic hyper crossover and chromosomal instability.

Children are increasingly recognised as having these disorders, particularly in the setting of Fanconi anaemia, ataxia telangiectasia and Bloom's syndrome. Juvenile myelomonocytic leukaemia and the monosomy-7 syndrome are relatively common; therefore the index of suspicion must be high when faced with otherwise unexplained signs and haematological abnormalities.

Bloom's syndrome is characterized by severe pre- and postnatal growth deficiency, a sun-sensitive erythematous face, well-demarcated hyper- or hypopigmented skin lesions and variable immunodeficiency [21].
Similar patterns of chromosomal instability have been found in other premature ageing syndromes, such as Bloom's syndrome where chromosomal breaks are readily apparent [48].

Two teams of scientists have independentlyfound that an enzyme deficiency may be responsible for the rare human disease called Bloom's syndrome. The disease carries an increased risk of leukemia and lymphoma, and is one of a small group of inherited diseases in which an abnormal amount of unrepaired chromosomal breakage occurs.
