An Unusual Presentation of Ornithine Transcarbamylase Deficiency Starting from Hyperthyroidism

Xu Zhenran , Wang Yixue , Chen Weiming , Luo Feihong , Lu Wei

Background: Late-onset ornithine transcarbamylase deficiency (OTCD) is a clinical challenge due to its nonspecific symptoms and the potential for delayed treatment. Hyperammonemia caused by acute metabolism disorder leads to life-threatening encephalopathy. We presented a unique case of OTCD initially manifesting with hyperthyroidism, resulting in refractory hyperammonemia.Case report: A previously healthy 14-year-old Ch...

Mandibulofacial dysostosis with microcephaly (MFDM) is characteristic of multiple skeletal anomalies comprising craniofacial anomalies/dysplasia, microcephaly, dysplastic ears, choanal atresia and short stature. Loss of function mutations of EFTUD2 were previously reported in MFDM, however, the mechanism underlying EFTUD2-associated skeletal dysplasia remains unclear. Here, we identified a novel frameshift mutation of EFTUD2 in a MFDM Chinese patient...

A de novo Pathogenic Heterozygous Mutation of the Insulin Receptor gene in a Patient with type A Insulin Resistance Syndrome

Sun Manqing , Wang Wei , Lu Wenli , Zhang Lidan , Dong Zhiya , Xiao Yuan , Ma Xiaoyu , Ni Jihong , Wang Defen

Background: Defects of the insulin receptor gene (INSR) can cause genetic syndromes associated with a wide diverse range of congenital insulin resistance from milder insulin-resistant diabetes mellitus (Type A insulin resistance syndrome, TAIRS) to leprechaunism (Donahue syndrome). Clinical features in TAIRS vary due to the severity of damage in INSR, precise diagnosis is challenging.Materials and Methods</stron...

Clinical and Molecular Genetic Characterization of Two Patients due to Mutations

Ding Yu , Li Niu , Chang Guoying , Li Juan , Yao Ruen , Shen Yiping , Wang Jian , Huang Xiaodong , Wang Xiumin

Background: The Phosphoglucomutase 1 (PGM1) enzyme plays a central role in glucose homeostasis by catalyzing the inter-conversion of glucose 1-phosphate and glucose 6-phosphate. Recently, PGM1 deficiency was recognized to cause the congenital disorders of glycosylation (CDGs). PGM1 deficiency is a rare, autosomal recessive inherited disease which can cause the extreme variability of clinical symptoms multi-organ dysfunction, including ketotic hypoglycemia, dilated cardiomyopat...

Targeted/Exome Sequencing Identified Mutations in 55 Chinese Children Diagnosed with Noonan Syndrome and a Autosomal Recessive form Associated with LZTR1 Variants

Li Xin , Yao Ruen , Chen Yao , Chang Guoying , Ding Yu , Li Juan , Shen Yiping , Wang Xiumin , Wang Jian

Background: Noonan syndrome (NS) is generally considered an autosomal dominant, multisystemic disorder caused by dysregulation of the RAS/mitogen activated protein kinase (MAPK) pathway. The latest research confirmed the existence of a form of Noonan syndrome that is inherited in an autosomal recessive pattern and identify biallelic mutations in LZTR1. In this study, we diagnosed 55 Chinese NS Children via targeted sequencing or whole exome sequencing (TS/WES).<p ...

Objective: To establish INS-1 cell iron overload model, and study the effect on iron overload, proliferation, insulin secretion, mitochondria defect and oxidative stress change.Methods: INS-1 cells were cultured with different concentrations (0 as control and 5, 10, 20, 40, 80,160,320µmol/L respectively) of ferric ammonium citrate (FAC). Labile iron pool (LIP) were calculated by detecting calcein-AM fluorescence ...

Effects and Safety of Recombinant Human GH in GH Deficient Children with Rathke Cyst

Liang Liyang , Zhang Lina , Meng Zhe , Ou Hui , He Zhanwen , Hou Lele , Li Dongfang , Li Pinggan , Luo Xiangyang

Objective: To assess the effects and safety of recombinant human GH (rhGH) in GH deficient (GHD) children with Rathke cyst.Methods: The clinical data of 12 GHD children aged from 5–12 years old, whose radiologic diagnosis showed Rathke cyst during Jan 2010–Dec 2012 in our hospital, were analyzed retrospectively. rhGH was given subcutaneously to each enrolled child with a night dose of 0.1 IU/kg six to seven times a week for 12–30 months. T...

Objective: This study aimed to investigate the therapeutic effects of recombinant human GH (rhGH) combined with low-dose stanozolol on the growth and final adult height (FAH) of girls with Turner syndrome (TS).Method: A total of 47 girls with TS were treated with rhGH (47.6–52.4 μg/kg per day) and low-dose stanozolol (20–35 μg/kg per day), starting at a mean age of 12.57±1.96 year. The control group consisted of 26 girls with TS,...

Background: Data on prevalence and phenotypic distribution of dyslipidaemia in children with type 1 diabetes (T1D) is scarce. Studies have shown that lipid abnormality tracks from childhood to adulthood and contributes to atherosclerotic process, therefore initial assessment and follow-up is essential.Aims: To study the prevalence and phenotypic distribution of dyslipidaemia in children with T1D and compare with type 2 diabetes (T2D).<p class="abstex...
