Bloom's syndrome is an autosomal recessive genome-instability disorder associated with a predisposition to cancer, premature aging and developmental abnormalities. Bloom syndrome, also called Bloom-Torre-Machacek syndrome or Congenital Telangiectatic Erythema, is a rare genodermatosis characterized by genomic instability and predisposition to the development of a variety of cancers. Choong et al 1999 , Kratz et al 2005 ]. Genetic testing can reveal if a person has mutations in the BLM gene, which are known to cause Bloom Syndrome.

Yankiwski V, Marciniak RA, Guarente L, Neff NF: Proceedings of the National Academy of Sciences of the United States of America. Bloom syndrome is inherited in an autosomal recessive pattern. Since BLM gene encodes the protein RecQ DNA helicase which is responsible for DNA repair, BS is considered a genome instability syndrome, associated with high predisposition to malignancy [].BS was first discovered in 1954 by the dermatologist David Bloom []. People with Bloom Syndrome have. Average Weight: 50 poundsAverage Height: Less than 5ft Average Life Expectancy: 24 years Old 4. INTRODUCTION. BS is caused by mutations in the BLM gene which is a member of the RecQ DNA helicase family. PMID 10779560 : Binding and melting of D-loops by the Bloom syndrome helicase. It is caused by mutations that inactivate the DNA helicase activity of the BLM protein or nullify protein expression. Bloom syndrome (BSyn) is characterized by severe pre- and postnatal growth deficiency, immune abnormalities, sensitivity to sunlight, insulin resistance, and a high risk for many cancers that occur at an early age. The causative gene has been mapped to chromosomal location 15q26.1 and is responsible for making a protein known as BLM. The Bloom syndrome gene product is related to the RecQ subset of DExH box-containing DNA helicases and has both DNA-stimulated ATPase and ATP-dependent DNA helicase activities. Bloom Syndrome: A rare genetic inherited genetic disorder which mainly affects Ashkenazic Jewish people and is characterized by short stature, malar hypoplasia, and a telangiectatic erythema of the face. Bloom syndrome is a very rare autosomal recessive genetic disease that stems from mutations in genes responsible for DNA repair.
