Background: Costello syndrome is a rare congenital disorder with characteristic findings involving multiple organ systems. The Costello Syndrome Family Network estimates that the birth prevalence in the United Kingdom is at least 1/500,000. So far, there has been only one affected individual reported in China.Objective and hypotheses: Diagnose the case of autosomal dominant Costello syndrome by direct squencing of HRAS gene. Analyze the correlation betwe...

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 ...

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...

Background: Rathke’s cleft cyst (RCC) has been reported rarely in children and adolescents. The occurrence of RCC with hypoplastic anterior pituitary can be explained by their common embryologic origin. However, the effects and sfety of recombinant human GH (rhGH) in GH deficient (GHD) children with RCC has not been previously reported.Objective and hypotheses: To assess the effects and safety of recombinant human GH (rhGH) in GH deficient (GHD) chi...

Objective: To investigate the clinical features and genetic characteristics of HRAS-associated Costello Syndrome.Method: Characteristics of clinical data and gene mutation of two cases Costello Syndrome in XX hospital were retrospectively analyzed. The related literature was searched by using search terms ‘HRAS’ or ‘Costello Syndrome’.Result: Both patients were presented with mental retardation, growth retardati...

Objective: The aim of this study was to detect potential gene mutation of Noonan Syndrome in a Chinese family.Methods: Patient with clinical diagnosis and parents were analyzed in this study. The analysis included medical histories, clinical analysis, and genetic tests. The PTPN11, KRAS, SOS1, RAF1, NRAS, BRAF, RIT1, SOS2, LZTR1, SHOC2, CBL, NF1 gene was sequenced to identify the pathogenic mutation responsible for the development of Noonan Syndrome by P...

Objective: The aim of this study was to detect potential gene mutation of idiopathic hypogonadotropic hypogonadism Syndrome (IHH) in a Chinese family.Methods: Patient with clinical diagnosis and parents were analyzed in this study. The analysis included medical histories, clinical analysis, and genetic tests. A Disorder of Sexual Development (DSD) gene panel was applied to identify the pathogenic mutation responsible for the DSD and verified by Sanger.</...

Objective: The aim of this study was to detect potential gene mutation of Methylmalonic acidemia (MAA) in a Chinese patient.Methods: Patient with clinical diagnosis and parents were analyzed in this study. The analysis included medical histories, clinical analysis, and genetic tests. A NGS panel include MUT,MMAA,MMAB,MMADHC and MCEE genes was identify the pathogenic mutation responsible for the MAA and verified by Sanger.Results: A...

Background: Short stature can be caused by mutations in a multitude of different genes. Cockayne Syndrome is a rare growth disorder marked by progressive growth failure, neurologic abnormality. The current report describes a patient with severe short stature and neurologic abnormality.Methods: Patient with clinical diagnosis and parents were analyzed in this study. The analysis included medical histories, clinical analysis, and genetic tests. The gene wa...

Background: The growth pattern of normal children was inappropriately used to evaluate those who with DSD.Objective: To understand growth and development of the 46, XY disorders of sex development (DSD) children, drawing height, weight and BMI curve of children with 46, XY DSD at the age of 0–16.Method: The registration database was used in this study. Non- CAH 0-16 years old 46, XY DSDs were collected. Growth curves were fitt...
