Type of disease: Rare conditions
2q37 deletion syndrome is a rare chromosome condition that can affect many parts of the body. Approximately 100 cases have been reported worldwide. This condition is characterized by weak muscle tone (hypotonia) in infancy, mild to severe intellectual disability and developmental delay, behavioral problems, characteristic facial features, and other physical abnormalities. 2q37 deletion syndrome is caused by a deletion of the genetic material from a specific region in the long (q) arm of chromosome 2. Most cases are not inherited. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
