Background: Maturity-onset diabetes of the young (MODY) is one of monogenic diabetes caused by a single gene defect. To date, 13 MODY genes have been identified. However, there is big discrepancy in genetic locus between the Asian MODY patients and Caucasian’s one.Objective and hypotheses: We conducted the whole exome sequencing in Korean clinical MODY families to identify novel variants for MODY and compare the result with Caucasian’s one....

Background: Children with bone-age advancement without any pubertal sign (asymptomatic precocious puberty, asmyptomatic PP) were reported (CW Ko,et al, at the Annual Meeting of ESPE, 2012 and 2013).Objective and hypotheses: In our follow-up study, some more children with asmyptomatic PP were enrolled additionally. We analysed their clinical and laboratory characteristics at the time of diagnosis, and they were followed-up prospectively t...

Background: As the human genome is further explored, multiple genetic anomalies at different loci are being found that confer varying degrees of predisposition to diabetes. MODY is the most common form of monogenic diabetes, accounting 2–5 percent of diabetes. Recently, we have found and reported three noble gene variants relating to MODY in Korean children (Shim et al, Horm Res Pediatr, 2015).Objective and hypotheses: This study was done to see the...

Background: Central precocious puberty (CPP) is mostly idiopathic, however, familial cases of CPP and evidence of genetic factors on pubertal timing by genome-wide association studies suggested genetic causes of CPP.Objective and hypotheses: Molecular defects in six genes (KISS1, KISS1R, LIN28A, LIN28B, TAC3, and TACR3) have been known to cause early activation of the hypothalamic-pituitary–gonad...

Background: Craniopharyngioma is the most common parasellar tumor in childhood arising from remnants of Rathke’s pouch. As the hypothalamus plays a vital role in regulation of body weight by balancing energy intake and expenditure, hypothalamic damage by structural lesions is one of the most common causes of hypothalamic obesity. This study investigated prevalence, risk factors for the development of hypothalamic obesity, and consequent morbidities in children following t...

Background: Kallmann syndrome is the most common form of hypogonadotropic hypogonadism and is associated with genes such as KAL1, KAL2, CHD7, NELF, PROK2, and PROKR2. Genetic factors in hypopituitarism are involved with the gene mutation of PROP1, POU1F1, HESX1, LHX3, LHX4, and PTX2. We found a novel mutation of the AVP gene in a Kallmann syndrome patient with hypopituitarism.Case presentation: The pa...

Hypochondroplasia (HCH) is an autosomal dominant inherited skeletal dysplasia with abnormal growth pattern and inadequate pubertal growth spurt. Achondroplasia and HCH have many similar phenotype, however, HCH show the mildest phenotype among FGFR3-associated skeletal dysplasia, and the radiologic findings are usually so subtle. We investigated to evaluate clue for the hypochondroplasia, and clinical and genetic characteristics of eleven Korean patients with HCH. We a...

Objectives: Owing to the tremendous advances in next-generation sequencing technology, numerous monogenic causes of growth disorders have been identified. Identifying novel rare genetic causes of short stature (SS) is quite challenging. In 2017, we reported a mutation analysis of 15 patients with undiagnosed syndromic SS or overgrowth. In this study, 6 mutations in another 10 Korean patients with unexplained syndromic SS are reported. The aim of this study is ...

Purpose: The Tanner-Whitehouse (TW) system is the method of choice for skeletal maturity assessment in both clinical practice and auxological research (Tanner et al. 1983), and it has been used to estimate skeletal maturity in groups of children from all over the world. This study aimed on analyzing the characteristic of the RUS maturity of Korea children by evaluating RUS maturity of Korea children using the TW3 method, compared with children in China and Japan<stron...
