Say-Barber-Biesecker-Young-Simpson syndrome (SBBYSS) is a rare and clinical well-described disease caused by de novo heterozygous mutations in KAT6B gene. Genitopatellar syndrome (GS) is also caused by the mutations of gene KAT6B and shares some common clinical symptoms with SBBYSS. The phenotypic spectrum caused by KAT6B is very broad that some patients cannot be classified as SBBYSS or GS. Herein, we report one de novo heterozygous KAT6B truncating variants c.5124delC (p.L17...

Objective: Clinical Observation of fifty-two patients with 5-alpha-reductase deficiency (5 - alpha-reductasedeficiency, 5α-RD) with oral testosterone undecanoate. To evaluate the efficacy and drug safety, find the optimum age of medication.Methods: Prospective self-controlled comparison methods were used to analyze the clinical data and follow-up results in sixty-nine patients who are diagnosed with 5-alpha-reductas...

Context: We investigate the efficacy and safetyof non-inferiority clinical trial for human chorionic gonadotropin/ human menopaousal gonadotropin (HCG/HMG) versus pulsatile gonadotropin-releasing hormone (GnRH) which have not been evaluated in puberty boys with CHH.Objective: To compare the efficacy and security of two different treatments in male adolescent patient with congenital hypogonadotropic hypogonadism (CHH).Methods: For t...

Objective: In boys during puberty who were undergoing recombinant human growth hormone (rhGH) treatment, we compared the therapeutic efficacy and any adverse reactions, of co-therapy with letrozole/gonadotropin releasing hormone analog (GnRHa).Methods: Fifty-six pubertal growth hormone deficiency (GHD) boys were studied, they were treated with the combination of letrozole and rhGH (letrozole group) or GnRHa and rhGH (GnR...

Background: Androgen insensitivity syndrome (AIS) is a common 46XY disorders of sex development (DSD), which is mainly caused by mutations in the androgen receptor (AR) gene. The clinical manifestations vary among patients, depending on residual androgen receptor activity.Methods: Five patients with different degrees of masculinization of external genitalia were selected as the research objects. As well as the detailed m...

Background: Thalassaemia patients are at risk of developing diabetes mellitus (DM) and pre-diabetes status predominantly due to iron overloading. The prevalence is 20–30% in adult patients. Age, serum ferritin, T2* magnetic resonance imaging (MRI) of the heart and pancreas volume has been found to be associated with DM. However, majority of the studies involved more adults than children.Objective and hypotheses: To establish the prevalence of glucos...

Single-nucleotide polymorphism (SNP) arrays have been widely used to identify novel genomic imbalances. Many of these genomic imbalances have been confirmed to interact with developmental delays, intellectual disabilities and congenital defects. Here, we identified a Chinese girl with a 3.18 Mb deletion at 12q12 (human genome build 19: 43,418,911–46,601,627). Deletions at 12q12 are extremely rare chromosomal imbalances; only five cases involving a deletion of this type ha...

Background: Thyrotoxic periodic paralysis (TPP) is a rare clinical manifestation of hyperthyroidism, commonly seen in Asian males. Patients often present with sudden onset muscle weakness associated with severe hypokalemia.Case presentation: A 16-year-old Filipino male presented with acute onset bilateral lower extremities weakness. He woke up at night but was unable to move his legs. He denied any recent viral infections, ingestion of canned food or his...

Background: Micropenis are the most common signs of incomplete masculinisation, but do not receive enough attention. The etiology is very complex, including endocrine factors, genetic factors and environmental endocrine disruptors.Objective and hypotheses: To explore 45 cases of micropenis children steroidogenesis factor 1 genetic abnormalities and to research the influence of the mutation on sex gland function.Method: 45 micropeni...

Cornelia de Lange syndrome (CdLS) is a multisystem organ developmental disorder characterized by growth and cognitive deficits and premature aging, caused by mutations in genes coding for the cohesin complex. CdLS cells presented with gene expression dysregulation, genomic instability, decreased energy production and oxidative stress. Variants in the cohesin loading factor Nipped-B-like (NIPBL) gene can be identified in approximately 70% of cases and the ...
