Background: The steroidogenic enzyme aromatase is encoded by the CYP19A1 gene. Aromatase activity is required for estrogen biosynthesis from androgen precursors in the ovary and several extragonadal tissues. The role of aromatase and thus estrogens for human biology is best illustrated by disease states, both deficiency and excess which might be caused by genetic disorders.Aim: A novel deletion-insertion mutation spanning from intron 10 to the 3...

Introduction: To achieve glycemic control goals in patients with type 1 diabetes (T1D), they are instructed in three fundamental principles: diet, insulin therapy and physical activity. Physical activity recommendations for children and adolescents with T1D are the same as for the general population. Following the physical activity recommendations helps mitigate the increased cardiovascular risk inherent to DM. We set out to explore the degree of glycemic cont...

Background and aim: C-peptide is an important indicator of endogenous insulin release. Our aim was to investigate the association of serum C-peptide levels with age, BMI and insulin doses in newly diagnosed type 1 diabetic (DM1) children.Metods: The patients with newly diagnosed DM1 were enrolled the study and classified as DM1A and DM1B. Clinical and laboratory findings of all the patients were recorded. Daily insulin doses, BMI and its z score were cal...

Introduction: Multisystem inflammatory syndrome in children (MIS-C) is associated with Covid-19. MIS-C was first reported in April 2020 with similar symptoms to Kawasaki disease and has several treatment options, one of which is glucocorticoids.Autopsy studies in Covid-19 patients have shown degenerative adrenal changes.It has been reported that rarely Covid-19 may affect adrenal function and cause both primary and secondary adrenal insufficiency.Here we prese...

Background: The phenotypic effects of single nucleotide polymorphisms (SNPs) may depend on their parental origin. PLAGL1 is an imprinted gene expressed from the paternal allele in placenta that is associated with fetal growth, transient neonatal diabetes mellitus and postnatal growth disorders. The mechanisms whereby PLAG1 regulates fetal growth are, however, unknown.Objective and hypotheses: To study if the preferential paternal transm...

Background: IPEX (OMIM #304790) is a rare and fatal, X-linked immune dysregulatory disorder caused by mutation in transcription factor FOXP3 that result in either quantitative or functional deficiencies of Tregs causing autoimmune disease and allergic inflammation. HSCT is the only curative therapy available for IPEX patients.Objective: Presented boy was born at 38th GW with birth weight 3380 g and birth length 50 cm. Three maternal brothers d...

Background: The most common single nucleotide polymorphism in the IGFBP3 promoter region occurs at position -202. This polymorphic variation occurs frequently and may influence GH responsiveness and somatic growth.Objective and hypotheses: This study aimed to assess the effects of IGFBP3 promoter polymorphism on growth in children.Method: Restriction fragment length polymorphism (RFLP)-based genotyping of the -202 single nucleotide...

We report and discuss a case of a girl who at birth underwent surgery for Hirschsprung Disease (HD). To closely investigate her condition, we used a Next Generation Sequencing (NGS) panel to carry out a study of some of the genes known as being associated with congenital megacolon (PHOX-2B, RET, EDN3, GDNF, ASCL1 and BDNF). This analysis showed a maternally inherited heterozygous variant in the RET protooncogene (c.734T>A, p.Val245Glu), which is not described in the scienti...

The synthesis of many peptides involves several post-translational steps which converts precursors into bioactive peptide. One of these steps results in the α-amidation of the C-terminal from a glycine through a bifunctional enzyme called the peptidylglycine α-amidating monooxygenase (PAM). Although the physiological role of Kisspeptin (KP) in the control of GnRH secretion is well known, the exact molecular form of the bioactive hypothalamic KP remains elusive. By ...

Purpose: Metabolic syndrome (MetS) is a state of chronic inflammation, and high-sensitivity C-reactive protein (hsCRP) indicates inflammation. This paper evaluates the association between hsCRP and MetS and its components in Korean children and adolescents.Methods: We analyzed the data of 1,247 subjects (633 males, 14.2 ± 2.7 years) from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016-2017.
