Background: Klinefelter syndrome, also known as 47, XXY, is a disorder characterized by tall stature, hypogonadism and mental retardation which is caused by nondisjunction events during meiosis and occurs in 500–1 000 live male birth. Here we report a patient with Klinefelter syndrome who presented with short stature, in contrast to common tall stature presentation and was diagnosed with GH deficiency.Case: A 7-year-old male presented with short sta...

Introduction: Maturity-onset diabetes of the youth (MODY), is a genetically and clinically heterogeneous group of diseases in the pancreatic β–cell that impair insulin secreation. It mostly caused by heterozygous mutations in one of 11 different genes associated with β–cell function. The aim of this study is detection of the distribution of both known and novel point mutations of these genes in Turkish population.Pati...

Background: Congenital hypothyroidism, one of the most important preventable causes of mental retardation, is a clinical condition characterized by thyroid hormone deficiency in newborns.Objective and hypotheses: Congenital hypothyroidism is most often caused by defects in thyroid development leading to thyroid dysgenesis. TSH receptor (TSHR) is the main known gene causing thyroid dysgenesis in consanguineous families with congenital hypothyroidism. In t...
