Shwachman syndrome is a rare genetic disorder that may be apparent at birth (congenital), during early infancy, or within the first few years of life. These may include increased tooth decay (dental caries), mouth ulcers, and/or disease of the tissues that surround and support the teeth (periodontal disease). Contact for additional information about Shwachman syndrome: (Please note that some of these organizations may provide information concerning certain conditions potentially associated with this disorder [e.g., pancreatic insufficiency and malabsorption, blood abnormalities, skeletal malformations, etc.].). Chromosomes are further subdivided into bands that are numbered. Individuals with Shwachman syndrome who experience recurrent infections and persistently low neutrophil counts (neutropenia) may be treated with granulocyte-colony stimulating factor (G-CSF). Please note that NORD provides this information for the benefit of the rare disease community. The occurrence of leukemia in patients with the Shwachman syndrome. These include red blood cells, which carry oxygen to the body's tissues; white blood cells, which fight infection; and platelets, which are blood cells that are necessary for normal blood clotting. (Eds), University of Washington, Seattle, Seattle (WA) 1993. As a result, affected individuals with neutropenia may be prone to repeated bacterial infections including respiratory infections (e.g., pneumonia); infections of the middle ear (otitis media); and repeated bacterial infections of other areas of the body. [Two cases of Shwachman-Diamond syndrome with genetic confirmation and literature review]. Neutropenia is the most common blood abnormality associated with Shwachman syndrome. If the pathogenic variant(s) in a family are known, prenatal and preimplantation genetic testing are possible. Because the disorder varies in severity from case to case and since there is no one test to make a diagnosis, it is difficult to determine the true frequency of Shwachman syndrome in the general population. Affected individuals with pancreatic insufficiency may require pancreatic enzyme supplements with meals to promote proper absorption of fats and other necessary nutrients during digestion.
