Objective: To report a family with MODY2 associated with GCK gene mutation and improve clinicians' understanding of this gene mutation.Methods: The clinical manifestations, laboratory examinations and genetic test results of a MODY2 family diagnosed and treated in our hospital were analyzed retrospectively, and the related literatures were reviewed.Results: The patient is a 6-...

Objectives: To present Chung-Jansen Syndrome or CHUJANS by a de novo variant in the pleckstrin homology domain-interacting protein (PHIP) gene and compare the clinical phenotype with previous case reports; ②To provide a novel genetic detection methods with whole-exome sequencing(WES) and whole genome sequencing(WGS) and Sanger sequencing for rare genetic diseases.Patients and methods: Following collecting clinical...

Objective: To report the clinical and gene mutation characteristics of a patient with lysine urinary protein intolerance (LPI) characterized by lupus nephritis, lupus encephalitis and extreme short stature, so as to improve understanding of the clinical characteristics of LPI caused by SLC7A7 gene mutation.Methods: The clinical manifestation, laboratory examination and gene test results of a child with LPI diagnosed and ...

Objective: To establish INS-1 cell iron overload model, and study the effect on proliferation, insulin-secretion and oxidative stress change.Methods: INS-1 cells were cultured in either normal or high glucose medium. Both groups were treated with different concentrations of (5, 10, 20, 40, 80 μmol/l respectively) of ferric ammonium citrate (FAC). Number and state of the cells were detected by trypan blue staining. Labile iron pool (LIP) were calcula...

Background: Growth failure and abnormal plasma glucose level are common in patients with thalassemia major (TM), which are usually due to iron overload after repeated blood transfusion. Patients after successful bone marrow transplantation (BMT) will be free from further blood transfusion and thus spared from complications of iron overload. This study aimed at determining the incidence of abnormal glucose level in TM patients and studying the height difference between the TM p...

Background: Dopa-responsive dystonia is a genetic disease that rarely reported in domestic and foreign. Its clinical characteristics is so complex and diverse that it is easy to lead to misdiagnosis and delayed treatment. However, early diagnosis and timely and appropriate treatment can completely improve symptoms. Fortunately, now we can take advantage of gene sequencing to diagnose this rare disease.Objective and hypotheses: Understand the research pro...

Background: Adrenoleukodystrophy (ALD) is a genetic disease associated with demyelination of the CNS, adrenal insufficiency, and accumulation of very long-chain fatty acids in tissue and body fluids.Objective: To research the clinical features, laboratory tests, imaging examinations and treatment on children who suffer from X-linked ALD. Also aim at revealing the correlation between the severity of disease and level of very long chain fatty acids (VLCFAs...

Context: ACAN gene is located at 15q26.1 and encodes aggrecan, which is a critical proteoglycan component of cartilage extracellular matrix. Heterozygous variants in ACAN are associated with short stature, premature growth cessation, and impaired bone maturation. A comprehensive understanding of the genetic and clinical characteristics of patients with ACAN mutations helps to improve the overall management of an individual.<p cla...

Objective: To explore the status and the main influencing factors of peripheral nerve conduction dysfunction in Chinese children and adolescents with type 1 diabetes mellitus (T1DM).Methods: Nerve electrophysiological indicators including amplitude, latency and conduction velocity of median nerve, ulnar nerve, superficial peroneal nerve, sural nerve, common peroneal nerve and tibial nerve were collected, and the results ...

Objective: To analyze the clinical features and causative genes in children with undiagnosed short stature and study the causative genes in our hospital. Methods Clinical manifestations, laboratory test and whole exome sequencing (WES) results of children with undiagnosed short stature who visited pediatric endocrinology department of our hospital from January 2018 to August 2019 were analyzed retrospectively. Causative genes were classified and analyzed accor...
