Resistance to thyroid hormone (RTH) is a rare genetic disease caused by reduced tissue sensitivity to thyroid hormone. The hallmark of RTH is elevated serum levels of thyroid hormone with unsuppressed thyrotropin (TSH). The most common form of RTH results from minor defects in the ligand-binding domain of the TRb gene, resulting in impaired T3-induced transcriptional activity. This study aimed to characterize clinical and genetic features of THD suspected cases in our clinic. ...

Introduction: A rare cause of diabetes mellitus is Wolfram Syndrome, which arises from mutations in wolframin gene found on chromosome 4. Optic nerve atrophy, diabetes insipidus, sensorineural deafness, psychiatric problems can accompany diabetes mellitus, so it can be also named as DIDMOAD syndrome. Hypergonadotrophic hypogonadism can be rarely observed in Wolfram syndrome. A case of novel homozygous mutation in the wolframin gene has been reported because of concomitant rare...

Introduction: The most common type of diabetes in childhood is type-1 diabetes. The group of diabetes called MODY (maturity-onset diabetes of the young) is rarer. Mutations that occur in glucokinase gene cause disruption in the perception of the resultant glucose level and, consequently, impaired insulin release, leading to the development of MODY-2. In this case, resulting hyperglycemia is usually at a mild, non-progressive level and does not require insulin therapy. For this...

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...

The weight of birth affects the weight status and fat distribution in the later period of life. It is suggested that both low and high birth weight pose a risk for cardiometabolic diseases. In this study, the effects of birth weight on body fat mass and body fat distribution parameters during childhood and adolescence period were evaluated.Method: In this cross-sectional study, 4581 children ages between 6-17 years at primary and secon...

Context: PPP2R3C encodes the B”gamma regulatory subunit of the protein phosphatase 2A (PP2A), which is a serine/threonine phosphatase involved in the phospho-regulation processes of mammalian cells. We have recently reported homozygous and heterozygous mutations in PPP2R3C in patients with syndromic 46,XY complete gonadal dysgenesis (MEGD syndrome) and impaired spermatogenesis, respectively. In this study, we have further investigated th...
