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...

Background: Maturity-onset diabetes of the young, type 2 (MODY2), caused by mutations in the glucokinase (GCK) gene is rare in a Chinese population.Objective and hypotheses: We report three Chinese families with MODY2 and sequenced the GCK gene to find novo mutation.Method: Three unrelated Chinese families with MODY2 and pedigrees were investigated. In Family 1, the proband was a 7-year-old girl with impaired fasting glucose (IFG) ...

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: Aromatase inhibitors (AIS) can block the conversion of androgens to estrogens, thus can be used to delay bone maturation in males, however, the effect on improvement of final adult height (FAH) is still controversial.Objective and hypotheses: A prospective study was performed to evaluate the effect of letrozole used on the FAH in males with idiopathic short stature (ISS).Method: 55 boys with ISS and had entered puberty ...

Background: The incidence rate of maturity onset diabetes of the young (MODY) and the proportion of different types of MODY will be different in different countries and races. GCK, HNF1A, and HNF4A are the three most common types of MODY, but the occurrence of other rare MODY subtypes in Chinese children is unknown. Therefore, studying the case group of MODY in Chinese children can help deepen understanding of MODY, early identification, and precise treatment....

Background: FOP is an ultra-rare, severely disabling genetic disorder characterised by progressive heterotopic ossification (HO) following flare-ups. The median age at diagnosis is 5 years, and patients are managed by multiple specialties. No study to date has provided a longitudinal evaluation of FOP. Final data are presented for participants, aged <25 years, enrolled in the first 36-month, prospective, global natural history study of FOP (NCT02322255).</...

Objective: To summarize the clinical characteristics, genetics and follow-up data of five children with thyroid hormone resistance syndrome (RTH) and review the related literatures.Methods: The clinical data of the five children diagnosed with RTH in our hospital from 2018 to 2020 were retrospectively analyzed. Next-generation sequencing of the candidate genes related to thyroid diseases was performed using the blood col...

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...

Purpose: To evaluate the efficacy of supervised Artificial Neural Network (sANN) in bone age assessment and compare the diagnostic performance of sANN-based TW3 skeletal maturity assessment on hand radiographs with that of experienced child endocrinologists.Materials and methods: This study developed an optimized artificial intelligence TW3 bone age assessment system by using the sANN and rating for the 20 hand bones (13RUS+7carpal) from A to I. 8332 of ...
