Chen Hongshan , Li Dan , Zhang Yuanyuan , Huang Siqi , He Xiaohua

Objective: We aim to investigate the association among progranulin (PGRN), high-mobility group box 1 (HMGB1), and obesity related markers in young rat model of high fat diet-induced obesity.Materials and Methods: 20 Male Sprague-Dawley (SD) rats at the age of 21 days were divided into two groups randomly. The rats were fed with normal diet (NC group) or high-fat diet (OB group). The NC group and OB group were sacrificed ...

A Novel MAP3K1 Gene Mutation (c.556A>G) Associated with 46, XY Complete Gonadal Dysgenesis

Zhu Yilin , Chen Hong , He Minfei , Liang Li , Wang Chunlin

Introduction: Complex and ordered intracellular signal pathways play a significant role in sex determination in mammals, mediating the balance of gonadal development. A major pathway involved in the regulation of the male development is mitogen-activated protein kinase (MAPK) signaling pathway. To date, mutations of MAP3K1 gene have been found to account for approximately 15%-20% of 46, XY gonadal dysgenesis (46, XY GD)....

Case Report of Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) Caused by Rare AVPR2 Gene Active Mutation

li wenjing , chen jiajia , sun jiapeng , gong chunxiu

Objective: The AVPR2 gene mutation usually cause nephrogenic diabetes insipidus. We report a patient who carried an active gene mutation of AVPR2 presenting persistent hyponatremia, which resembled to the syndrome of inappropriate antidiuretic hormone secretion (SIADH)Method: We describe a patient whose clinical and laboratory evaluation were consistent with hyponatremia, which hardly to be corrected to normal. After the...

NSD2 Mutation in a Family with a New Intellectual Disability and Short Stature Syndrome: a 7.5 Years Follow-Up

Hu Xuyun , WU Di , Li Yuchuan , Gong Chunxiu , Shen Yiping

Wolf-Hirschhorn syndrome is a genomic disorder caused by 4p16.3 deletion with facial dysmorphology, growth retardation, developmental/intellectual delay and seizures. After 165 kb critical region encompassing NSD2 was identified, most recently, three NSD2 loss of function variants was uncovered in patients with overlapping phenotype with Wolf-Hirschhorn syndrome. In our study, a NSD2 variant, c.1577dupG (p.Asn527fs*14) was identified in two patie...

Whole Genome Sequencing Reveals Novel Intragenic Deletions of GNAS as Causes of Pseudohypoparathyroidism Type 1a

Li Dong , Bupp Caleb , Hakonarson Hakon , Levine Michael

Background: Pseudohypoparathyroidism type 1a (PHP1a) is characterized by Albright hereditary osteodystrophy (AHO) and multi-hormone resistance, most commonly to parathyroid hormone (PTH) and thyroid-stimulating hormone. This rare disorder is caused by inactivating mutations involving exons 1–13 of the imprinted GNAS gene that encodes the alpha-subunit of the stimulatory G protein (Gαs). Due to paternal imprinting of Gαs transcripts, GNAS mutati...

Continuous Glucose Monitoring Profiles in Healthy Non-Diabetic Children and Adolescents: A Multicenter Prospective Study

DuBose Stephanie , Li Zoey , Beck Roy , Tamborlane William

Since CGM-based outcomes that are increasingly being used in clinical pediatric diabetes research, this study was aimed at gathering normative sensor data in healthy, non-diabetic children using the recently approved DexCom G6 system. In this multicenter study, healthy, non-diabetic children and adolescents (age 7 to <18 years, BMI between 5th and 85th percentile, and HbA1c <5.7%) were included. Each participant wore a blinded DexCom G6 for approx. 10 days and kept a d...

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.</...

A Novel Mutation in 5’; Untranslation Region of Makorin Ring Finger 3 Gene Associated with the Familial Precocious Puberty

Lu Wenli , Wang Junqi , Li Chuanyin , Hu Ronggui , Wang Wei

Central precocious puberty (CPP) is the endocrine disorder triggering by many factors those can activate the hypothalamic-pituitary-gonadal axis early which controlled GnRH secretion. However, the mechanism of CPP has not been elucidated. The study of patients with familial CPP helped understanding the complex physiological processes. Recently, loss-of-function mutations in human Makorin ring finger protein 3 (MKRN3) were found to contribute to over 30% of cases of familial CP...
