Individuals with thrombocytopenia may bruise easily and, without appropriate precautions, be prone to abnormal bleeding; however, episodes of severe bleeding are rare. Acta Paediatr Scand. Accessibility 1984;73:642-51. Shwachman-Diamond syndrome is an autosomal recessive disorder with clinical features that include pancreatic exocrine insufficiency, haematological dysfunction and skeletal abnormalities. A transplant is done to replace the bone marrow (and consequently the whole blood system) of an affected individual with marrow from a person who does not have a particular disorder. However, characteristic features include insufficient intestinal absorption (malabsorption) of fats and other nutrients due to abnormal development of the pancreas (pancreatic insufficiency); failure to grow and gain weight at the expected rate (failure to thrive) during the first years of life, contributing to short stature; distinctive abnormalities of the skull and facial (craniofacial) region; hearing impairment due to inner ear abnormalities (sensorineural hearing loss); and/or intellectual disability. Clin Exp Immunol. Recessive genetic disorders occur when an individual inherits the same abnormal gene for the same trait from each parent. For example, in almost 50 percent of cases, older children may begin to have normal stool patterns. Associated symptoms may include fatigue, abnormal paleness of the skin (pallor), and/or other findings. Agents/circumstances to avoid: Prolonged use of cytokine and hematopoietic growth factors (e.g., G-CSF) should be considered with caution. Gastroenterology.

Affected individuals with pancreatic insufficiency may require pancreatic enzyme supplements with meals to promote proper absorption of fats and other necessary nutrients during digestion. These may include increased tooth decay (dental caries), mouth ulcers, and/or disease of the tissues that surround and support the teeth (periodontal disease). Some evidence suggests that an increased predisposition to the development of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) may potentially be associated with structural abnormalities of chromosome 7 (e.g., chromosome 7 monosomy or deletion of all or a portion of the long arm [q] of chromosome 7). 1982;71:677-79. 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.

Perform neuropsychological screening in children age 6-8 years, 11-13 years, and 15-17 years. Het Shwachman Diamond Syndroom (SDS) is een zeldzame erfelijke aandoening. For example, such changes may cause an abnormal reduction in the angle of the thigh bone or the knee, potentially resulting in shortening of the leg, stiffness, and/or limping. Chromosomes are further subdivided into bands that are numbered. In addition, the pancreas lacks the sufficient amount of digestive enzymes required to break down food and absorb fats and nutrients properly (pancreatic insufficiency). [delayed motor and speech development]); however, by school age, affected children usually reach their expected milestones. In addition, improper bone development (abnormal ossification) within the arms and/or legs (limbs) may cause growth delay in particular bones. Sokolic RA, et al.

The Shwachman-Diamond syndrome (SDS), characterized by bone marrow failure, exocrine pancreatic dysfunction, and skeletal abnormalities, is a rare inherited autosomal recessive disease, with ∼90% of the patients harboring inheritable mutations of the Shwachman-Bodian-Diamond syndrome (SBDS) gene at chromosome 7q11 (Myers et al., 1993, Myers et al., 2013, Popovic … Malignancies and survival patterns in the National Cancer Institute inherited bone marrow failure syndromes cohort study. Reports indicate that the disorder affects males and females by a ratio of approximately 1.7 to 1. 2004;104(12):3588-90. Comparisons may be useful for a differential diagnosis: Cystic fibrosis is an inherited disorder that affects many exocrine (“outward-secreting”) glands of the body, including the sweat glands, salivary glands, and those within the pancreas and respiratory system. Shwachman-Diamond syndrome: clinical, radiological and sonographic aspects. 1982;2:800-01. In cases where limb bone changes occur, the region where the long shaft of the bone (diaphysis) meets its growing end (epiphysis) may develop improperly (metaphyseal dysostosis). Kent A, et al.

In addition to the name Shwachman syndrome, alternative terms for the disorder include Shwachman-Bodian syndrome and Shwachman-Diamond-Oski syndrome. As a result, there is a deficiency in the amount of digestive enzymes required to break down food (pancreatic insufficiency), which, in turn, prevents fats and other essential nutrients from being absorbed properly (malabsorption). In individuals with the disorder, glands within the lining of tubular air passages (bronchi) in the lungs produce unusually thick, sticky secretions of mucus, clogging and obstructing the air passages. Shwachman-Diamond syndroom (SDS) is een aangeboren aandoening aandoening van het beenmerg, de botten en de alvleesklier. ), There are additional disorders that may be characterized by various blood (hematological) abnormalities such as neutropenia, thrombocytopenia, and/or anemia occurring in association with other findings that may be similar to those potentially associated with Shwachman syndrome.

Although individuals with Shwachman syndrome and cystic fibrosis may have certain similar symptoms (e.g., steatorrhea and other findings associated with pancreatic insufficiency and malabsorption), individuals with Shwachman syndrome have normal concentrations of electrolytes in their sweat, while those with cystic fibrosis have abnormally elevated concentrations of sodium and chloride. Carrier testing for relatives at risk is possible if both pathogenic variants in a family are known. (An isochromosome is an abnormal chromosome with identical arms on each side of the centromere.) Br J Haematology. Such tests may include stool tests, blood tests, and/or analysis of secretions from the pancreas that are released into the duodenum. The severity of the abnormality varies greatly from case to case. Mack DR, et al. In addition, physicians may regularly monitor affected individuals for hematological abnormalities associated with bone marrow dysfunction (e.g., regular blood counts) to ensure proper preventive measures and early, prompt treatment.

Ginzberg H, et al. Consider prophylactic antibiotics and G-CSF to reduce risk of infection during complex dental procedures or orthopedic surgery. The diagnosis of SDS is established in a proband with the classic clinical findings of exocrine pancreatic dysfunction and bone marrow dysfunction and/or by identification of biallelic pathogenic variants in DNAJC21, EFL1, or SBDS, or a heterozygous pathogenic variant in SRP54. In such cases, the abnormal formation of scar tissue within heart muscle (myocardial fibrosis) may result in tissue damage and loss (necrosis) in certain areas of the heart (e.g., left ventricle), potentially resulting in life-threatening complications (e.g., heart failure). Johanson-Blizzard syndrome (JBS) is a rare genetic disorder that may be apparent at birth or early childhood. Diagnosis/testing: Therefore, physicians will closely monitor an affected individual's hematological status to ensure early detection and prompt, appropriate treatment.

Individuals may print one hard copy of an individual disease for personal use, provided that content is unmodified and includes NORD’s copyright. In individuals with Shwachman syndrome, intestinal malabsorption results in large, loose, foul smelling stools that contain an excessive amount of fat (steatorrhea) and other nutrients.
