Background: Bardet Biedl syndrome(BBS) is a type of non-motile ciliopathy primarily characterized by retinal dystrophy, obesity, polydactyly, cognitive impairment, urogenital anomalies and renal abnormalities. To date, 26 genes have been reported to be associated with BBS: BBS1-BBS21, IFT74, SCLT1, SCAPER and NPHP1. BBS is genetically heterogeneous with significant clinical overlap with other ciliopathies, further c...

Objective: To explore the clinical features and the genetic cause of a multiple malformation patient with short stature.Methods: The clinical data was collected in Beijing Children’s Hospital in November 2017. The disease-causing variant was identified using exome sequencing and confirmed with Sanger sequencing. Related literature was searched from Wanfang and Pubmed databases using the key word of ‘PORCN gene’ to identify the clinical fea...

Background: Primary ciliary dyskinesia (PCD) is a type of ciliary dyskinesia that is usually caused by autosomal recessive inheritance and can manifest as recurrent respiratory infections, bronchiectasis, infertility, laterality defects, and chronic otolaryngological disease. Although ependymal cilia, which affect the flow of cerebrospinal fluid in the central nervous system, have much in common with respiratory cilia in terms of structure and function, hydroc...

Background: Evidence of the association between vitamin D, insulin resistance and oral disposition index (oDI) in obese children and adolescents is limited.Objective and hypotheses: We investigated serum 25(OH)D levels in obese children and adolescents in Zhejiang, China, and determined the relationship between serum 25(OH)D and glucose metabolism.Method: A cross-sectional design was used. All together 348 obese and 445 non-obese c...

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...

Congenital hypothyroidism can be caused by the wrong formation of the thyroid gland or the defect in the synthesis of thyroid hormone. Among the candidate genes, defect in the gene NKX2-1 can be presented as thyroid, lung, or brain dysfunction. An eight-year-old boy was diagnosed as congenital hypothyroidism at the age of 16 days. He was referred to our Pediatric Endocrinology Clinic due to elevated TSH level (36.28uIU/mL). Serum total T3 and free T4 were 125 ng/dL an...

Background: Several studies have shown that born small for gestational age (SGA) children have earlier precocious puberty, progress faster, and are less likely to gain target height in adults than children born appropriate for gestational age (AGA). Moreover, SGA children are more prone to metabolic disorders - obesity, diabetes and cardiovascular disease.Objective: To compare the physical development status, serum lipid...

Introduction: People’s weight-related behaviors may be influenced by their personal social network (SN), notably via family and friends’ behavioral modelling and motivational social support (SS).Objective: We examined the cross-sectional relation between social network-based social support (SS) and weight-related outcomes among adolescents ina pilot study within the QUALITY cohort, a longitudinal study investigating the natural...

Objectives: To summarize the diagnosis and treatment course of hyperkalemia in twins, review the diagnosis approach of hyperkalemia in neonate and guide clinical practice.Methods: The clinical manifestation, laboratory examination, the course of diagnosis and treatment of the two cases were summarized.Results: A pair of twin girls, 38 days after birth, came to our department because of ‘Hyperkalemia more than one month’. ...

Objective: To identify genetic mutations of a pedigree affected by severe short stature in Chinese populations for the first time.Methods: Auxological and endocrinological profiles were measured. Targeted next-generation sequencing (NGS) analyses comprising 277 shorted stature-associated candidate genes and 19 related copy number variation (CNV) regions were used to identify gene mutations in the proband. Three web-based software programs (SIFT, PolyPhen...
