Abstract:
Objective A 10-years-old girl with Schimke immuno-osseous dysplasia ( SIOD ) was reported and a literature review presented to provide clinical and genetic information of this rare disease. Methods Retrospective analysis of a case of SIOD in Capital Institute of Pediatrics was reported. The patient and her parents' DNA were extracted from blood for detecting SMARCALl gene mutation. Literatures of the disease were reviewed. Results The patient was a ten-years-old girl who admitted because of slow growth in height for 3 years. Herstaturewas123cm(T(p.Q149X)andc.1933C>T(p.R645C)compound heterozygous mutation. A novel nonsense c.445C>T(p. Q149X)was found. One reported missense mutations c. 1933C>T(p. R645C) was detected. We reviewed literatures and found that there were 4 confirmed cases in China including this one. All the 4 cases had the characteristic of short stature, special facial features, osseous dysplasia, pigmentations in body, and proteinuria. However the severity of the disease and genetic changes are not the same. Conclusion When a patient was admitted because of short stature, diagnosis of SIOD should be suspected if he or she also had special facial feature, osseous dysplasia, café-au-lait spots, and proteinuria. Gene test is a tool to help us to make a definite diagnosis of SIOD.
