Copy Number Variation (CNV) Sequencing Identifies a Novel Mutation of the Glucokinase Gene in Maturity-Onset Diabetes of the Young

Li Yan , Li Pin

Backgrounds: Maturity-onset diabetes of the young (MODY) is a cluster of early-onset, monogenic disorders which is inherited in autosomal dominant form. It is mainly caused by genetic defects in beta-cell, which results in beta-cell dysfunction. Till now, 14 MODY types specified by mutation in respective 14 genes with their etiologies are known. Among them, glucokinase (GCK) gene encodes glucokinase enzyme which plays a crucial role in the regulation of insuli...

Clinical and genetic analysis of ulnar-mammary syndrome caused by a novel TBX3 mutation in a Chinese boy and literature review

Yang Jianmei , Sun Yan , Li Guimei

Ulnar-mammary syndrome (UMS) is caused by TBX3 mutation and is a disorder characterized by altered limb, breast, tooth, hair, apocrine gland, and genital development. The detailed genotype-phenotype correlation of TBX3 -related diseases was analysed by the 5.5th UMS case analysis, and all reported cases of UMS were summarized and discussed.Methods: The clinical and genetic data of a boy with UMS were carefully analysed....

The Age of Pubertal Onset Correlates with Pubertal Growth Pattern and Body Weight Change in Girls

Li Yan-Hong , Du Min-Lian , Ma Hua-Mei

Background: Precocious puberty in girls may result in loss of FAH, and particularly may relates to obesity when entering adulthood. However,The influence of the timing of pubertal onset on the FAH and the change of body weight during pubertal stages is still controversial.Objective: The research is to investigate the pubertal growth pattern and the change of BMI levels in girls with ICPP and those who have normal onset of puberty but at different ages.</...

Chen Hong , Wang Chunlin , Liang Li , Yan Qingfeng

Objective: To investigate the clinical and molecular characteristics of a girl with 17α hydroxylase/17,20-lyase deficiency, of which, onset was as rhabdomyolysis and hypokalemia. And then we identified the functional consequences of two novel CYP17A1 mutations.Materials and Methods: A 11 years old girl, 46,XX karyotypes, presented with rhabdomyolysis, hypokalemia and hypertension. She had elevated levels of plasma adrenocorticotropic hormone, serum ...

Xie Liu-lu , Li Yan-hong , Ma Hua-mei , Du Min-lian

Background: McCune-Albright Syndrome(MAS)is a rare disease caused by somatic gain-of-function mutations of the GNAS gene, presenting with fibrous dysplasia(FD), cafe-au-lait spots and gonadotropin-independent precocious puberty(PP). Adenohypophyseal hyperfunction syndromes is reported uncommon but potentially severe complication of MAS.Method: A prospective study was performed to evaluate the prevalence of the pit...

Human chorionic gonadotropin (hCG)–secreting hepatoblastoma in an male infant with peripheral precocious puberty and 11-year follow-up

MA Hua-mei , LI Yan-hong , Chen Qiu-li , DU Min-lian

Background: Hepatoblastoma is the most common malignant pediatric hepatic tumor virtually confined to infants and young children. Accompanied by raised levels of alpha fetoprotein (AFP),rarely, the beta human chorionic gonadotropin (β hCG) levels may also be elevated, which can cause male peripheral precocious puberty (PPP).Objective: To report a case of HB presented with PPP with elevated serum AFP, β h...

Primary pigmented nodular adrenocortical disease in a young boy associated with a rare somatic mutation of the PRKACA: case report and literature review

Xu Yu-ying , Li Yan-hong , Chen Qiu-li , Ma Hua-mei , Zhang Jun , Guo Song

Introduction: Cushing's syndrome(CS) is rare in the pediatric population, and the cause vary with age. Primary pigmented nodular adrenocortical disease (PPNAD) is one of the causes of CS, though it is a rare disorder. It has been proposed that in children with CS, PPNAD should be suspected. Here we report a young boy with CS due to PPNAD associated with a somatic mutation of the PRKACA.Case Presentation: The child w...
