Objectives: KLF11 is a member of the Sp1/KLF family transcription factor which contains three C2H2 zinc finger domains. To date, two KLF11 mutations (p.T220M and p.A347S) have been identified in three families clinically diagnosed with type 2 diabetes. The aim of our study is to report clinical and molecular characteristics of a KLF11 mutation-carrying family clinically diagnosed with type 1 diabetes (T1D).Methods:...

Background: Vertical transfer of maternal cells to the fetus via the placenta leads to maternal microchimerism (MMc) in children. Previous studies from USA have shown that the prevalence and degree of MMc was significantly higher in patients with type 1 diabetes (T1D) than in their unaffected siblings and control individuals. To date, however, the frequency of MMc in non-Caucasian T1D patients remains to be examined.Methods</stro...

Introduction: McCune-Albright syndrome (MAS) is caused by somatic mosaic mutations in the GNAS gene. Detection of the GNAS mutations is usually difficult because of the low frequency mosaicism. Droplet digital polymerase chain reaction (ddPCR) is a new technology that enables to measure absolute quantities of target nucleic acids in a sample by counting nucleic acid molecules encapsulated in discrete water-in-oil droplet partitions.<p cla...

Background: Noonan syndrome (NS) is an autosomal dominant disorder characterized by a short stature, congenital heart defects, and characteristic facial features. Gain-of-function mutations of multiple genes in the Ras/mitogen activated protein kinase pathway have been identified in 70–80% of patients with NS. Recently, leucine-zipper-like transcription regulator 1 (LZTR1), which has not previously been associated with the pathway, was reported as a new causative...

Background: A school nurse and a school physician do screening of short stature and overweight by height and weight measured in the school health examination. Furthermore, in the municipality, practitioners are doing medical examination to preventing for children’s unhealthy lifestyle to applicants. However the pediatric endocrinologists of the ward sometimes examine the first visit patients with short stature, highly obese or type 2 diabete patients who have passed a few...

Background: In Japan, diabetic screening for school children using urinalysis has been performed to detect diabetes mellitus during childhood throughout the country. However, inadequate follow-up system after urinary screening caused several problems. The rate of participation in workup examination still remains less than 30%. Also, accurate annual incidences of children with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) detected by screening of urine glu...

Background: Interstitial deletions of the short arm of chromosome 11 are rare chromosomal anomalies, and are considered to be associated with several clinical conditions including WAGR syndrome.Objective: To report the clinical and molecular findings in the first case of a heterozygous 11p14.1-p15.3 deletion.Patient: A Japanese female patient was born at 39 weeks of gestation after an uncomplicated pregnancy and delivery. At birth,...

Background: Abdominal fat distributions are reportedly strongly associated with metabolic risks in type 2 diabetes mellitus. However, research on fat distribution in adolescents with type 2 diabetes mellitus has been limited.Aim: To investigate fat distribution characteristics in adolescents with type 2 diabetes mellitus for comparison to those with simple obesity in Japan.Design/Methods</s...

Objectives: This trial (NCT01927861) evaluated the growth-promoting effect and safety of Norditropin® (somatropin; recombinant human growth hormone) in Japanese children with short stature due to Noonan syndrome over four years of treatment.Methods: Pre-pubertal children diagnosed with Noonan syndrome were randomized 1:1 to receive Norditropin® 0.033 mg/kg/day or 0.066 mg/kg/day. Change in...

Background: While existing guidelines recommend long-term follow-up of childhood cancer survivors (CCS), transitional care among pediatric and adult endocrinologists has not been established in Japan.Objective and Hypotheses: To know the present situation and to cultivate a better understanding, we had conducted a nation-wide survey targeting Japanese pediatric endocrinologists.Method</stro...
