Congenital hyperinsulinemia occurs due to inappropriate insulin secretion from beta cells of the pancreas. It is the most common cause of resistant and recurrent hypoglycemia in neonates and infants and the threatment is very difficult. Although the incidence is reported as 1/50000, it is seen more frequently in consanguineous countries. Patients may present with lethargy, nourishment, irritability and seizures. If it is not treated, severe hypoglycemia may result in severe ne...

Objective: According to the etiology of hyperparathyroidism, it is divided into primer and secondary (uremic). It usually develops due to CaSR mutation in the infancy period. On the other hand, it usually emerges secondary to a parathyroid adenoma in adolescents. Parathyroid adenomas seen in childhood are commonly associated with familial multiple neoplasia syndromes (MEN). Patients may present with bone pain, proximal myopathy, fractures, renal stone, pancreatitis or they can...

Background: Type 2 diabetes is a heterogeneous disorder characterized by the defective of insulin, which can not progressively compensate for insulin resistance, due to the influence of environmental factors on the basis of genetic susceptibility. Hyperglycemia, which starts with insulin resistance, is thought to show toxic effects (glucotoxicity) on β cells and ultimately impairs beta cell function., Although many factors play a role in etiology, obesity is the most comm...

Background: 4p duplication syndrome is a very rare chromosomal disorder. In the literature; dysmorphic facial features, learning disability, speech retardation, overgrowth, musculoskeletal abnormalities, attention deficit hyperactivity disorder and autism syndrome have been reported to be associated with 4p16.3 duplication. Here we present a patient who admitted to our clinic with complaints of growth in hands and feet along with delayed speech and mental retardation. The gene...

Aim: Premature pubarche is defined as the start of axillary and pubic hair before age 9 in boys and 8 in girls. 10 times more common in girls than boys. Central precocious puberty is a condition due to early activation of hypothalamic-pituitary- gonadal axis associated with breast development before age 8 in girls and testicular volume growth before age 9 in boys. Despite this axle is not known exactly which hormones are respnsible for the activation, the role of kisspeptin&#1...

Background: Monogenic diabetes represents a group of disorders resulting from a single gene defect leading to disruption of insulin secretion or a reduction in the number of beta cells. Despite the classification of monogenic diabetes according to age of onset, with neonatal DM (<6 months of age) and maturity onset diabetes of young (MODY) (>6 months and <25 years of age); not every case can be classified into those groups.Objective and hypot...

Background: Osteogenesis imperfecta type XVII (OI17) (MIM#182120) have been described recently due to mutation in secreted protein, acidic, cysteine-rich (SPARC) gene located on 5q33.1.Objective and hypotheses: Here we report a novel mutation in SPARC causing OI17.Case: Two siblings presented to our clinic at the age of 10.3 and 0.5 years old. Parents were consanguineous. The older one was born with birth weight &...

Background: Osteogenesis imperfecta (OI) is a heterogeneous group of brittle bone disease mostly caused by quantative or qualitative defects in type I collagen. In most populations, more than 90% of the patients with OI have dominant mutations in COL1A1 or COL1A2 genes (AD-OI). Less than 10% of the cases have recessive inheritance (AR-OI). Currently 12 genes have been identified as a cause of AR-OI.Objective and hypotheses: We assumed h...

Background: Estimation of the child’s genetic height potential (target height) is an important tool in evaluating growth disorders. Midparental height (MPH) calculated as (Mothers height+Fathers height)/2±6.5 cm), used for this purpose, represents the child’s expected height based on parental heights.Objective and hypotheses: To evaluate the classical MPH calculations for our population and to explore the optimal MPH model using different ...

Background: Short stature (SS) is one of the most frequent reasons for referral to pediatric endocrinology clinics.Objective and hypotheses: We aimed to analyse the etiological factors of SS, in patients of our clinic, who are referred from general paediatrics with high likelihood of endocrinological problems after primary screening.Method: 1519 patients (693F) with height <3% were included. Clinical, anthropometric, radiologic...
