Presentation
[…] to us with chronic diarrhoea and failure to thrive.Case HistoryA 5-months old female child presented to us with a history of not gaining weight accompanied by diarrhoea since the neonatal period. [tropicalgastro.com]
Developmental and intellectual delays of variable degree are present in ~60% of cases. [orpha.net]
DISCUSSION Classic cases of JBS present in early infancy with syndromic features and severe exocrine pancreatic insufficiency. [pancreas.imedpub.com]
Clinical presentation There is wide variability in the clinical presentation, but common features are: low birth weight hypotonia intellectual disability (wide range) delayed skeletal maturation, short stature facial features microcephaly aplastic alae [radiopaedia.org]
Usually presents at birth when the nasal hypoplasia is associated with an imperforate anus. Prenatal diagnosis can be done. [accessanesthesiology.mhmedical.com]

Shwachman Syndrome: Congenital disorder characterized by pancreatic insufficiency, bone marrow dysfunction, and short stature; imperforate anus and Hirschsprung disease can be associated with this syndrome. [accessanesthesiology.mhmedical.com]
Additional features include dental anomalies (oligodontia/hypodontia (see these terms) of permanent teeth; >90%), sensorineural hearing loss (~75%), scalp defects (aplasia cutis congenital; ~65%), short stature (~60%), hypothyroidism (~40%), microcephaly [orpha.net]
We present here an infant with failure to thrive, exocrine pancreatic deficiency, short stature and developmental delay, cutis aplasia on the scalp, aplasia of alae nasi, hypospadias, hypothyroidism, myxomatous mitral valve, and patent ductus arteriosus [link.springer.com]
The main symptoms of the syndrome include the failure of the pancreas to absorb essential nutrients leads to a failure to thrive in many individuals, as well as a short stature, and a low weight. [fdna.health]

Treatment
Management and treatment Treatment includes oral administration of exogenous pancreatic enzymes and nutritional support (high-calorie diet with 30-40% calories from fat, lipase, fat-soluble vitamins and mineral supplementation) for pancreatic insufficiency [orpha.net]
Treatment The treatment for this syndrome is based on the specific symptoms that are evident in each of the cases. [mybiosource.com]

Prognosis
A better prognosis can be achieved by treating pancreatic insufficiency and hypothyroidism separately. [news-medical.net]
Prognosis Pancreatic insufficiency and complications of severe malnutrition (e.g. severe hypoproteinemia, vitamin deficiency, immunodeficiency) may lead to death in infancy or early childhood. [orpha.net]
Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis. Infants with JBS typically have distinctive craniofacial abnormalities at birth. [rarediseases.org]
Etiology
The possible etiologic basis for the hearing loss in this syndrome is discussed and the literature is reviewed. [semanticscholar.org]
Etiology Most cases of JBS are caused by mutations of UBR1 gene (15q13) which encodes a protein highly expressed in pancreatic acinar cells. [orpha.net]
No definite etiology could be established. This feature has not been described in previous reports of JBS. [wjgnet.com]
Epidemiology
Summary Epidemiology The prevalence of JBS in Europe has been estimated to be around 1/250,000 live births. [orpha.net]
Epidemiology JBS is predicted to affect 1 in every 250,000 people. There is no gender difference in JBS cases reported to date. Consanguinity between parents is a common occurrence. [news-medical.net]

On the basis of an epidemiological study on anorectal anomalies in Europe,9 a prevalence of roughly 1 in 250 000 life births was estimated.1 So far, no significant or ethnic differences of prevalence have been observed. [nature.com]
