Bloom syndrome is diagnosed by either cytogeneticanalysis or mutation testing. Cytogenetic analysis is used to detect if there is an increased amount of sister chromatid exchange in cells. Genetic testing can reveal if a person has mutations in the BLMgene, which are known to cause Bloom Syndrome. If an individual has a family history of Bloom syndrome, one of these two testing methods may be used to find out if the person has also inherited the condition. An unusually low birth weight and short height throughout childhood are suggestive of Bloom syndrome in an individual with an affected sibling.
