Johanson-Blizzard Syndrome (JBS) is a rare autosomal recessive genetic disorder characterized by exocrine pancreatic insufficiency, distinct abnormal facial appearance and varying degrees of growth retardation. Variants in UBR1 gene are considered to be responsible for the syndrome. Here, we describe a 3-year old boy, who visited our clinic for severe growth retardation and frequent oily diarrhea. The physical examination revealed nasal alae aplasia, scalp defect, and maldescent of left testicle. Transabdominal ultrasound and computed tomography scan of his abdomen demonstrated complete fatty replacement of the pancreas. The clinical, laboratory, and imaging findings strongly suggest the diagnosis of hereditary pancreatitis. Whole exome sequencing revealed two rare compound heterozygous variants, c.2511T > G (p.H837Q) and c.1188T > G (p.Y396X), in the UBR1 gene of this boy, so, the diagnosis of JBS was established. This is the first report of Chinese patient with JBS, and our study indicates that transabdominal ultrasound and computed tomography are two useful and noninvasive imaging methods for the diagnosis and evaluation of JBS, and identification of these two novel variants expands the database of UBR1 gene variants. Furthermore, with the availability of the identification technology for these variants, prenatal diagnosis could be offered for future pregnancies.
