A novel X-linked variant [c.1772delG (p.G591fs*20)] in IRS4 in a patient with central hypothyroidism

Koprulu Ozge , Tozkır Hilmi

Central hypothyroidism (CeH) is characterized by thyroid hormone deficiency due to impairment of pituitary TSH or hypothalamic TRH biosynthesis. CeH is often seen as a part of multiple pituitary hormone deficiencies, but it can also be seen as isolated. Diagnosis may be challenging. To date, some variants that can cause isolated CeH have been identified; although in a number of patients the cause has not been clarified. Recently, variants of the insulin receptor substrate 4 (<...

Introduction: Although the majority of the cases with obesity have a multifactorial etiology, rare monogenic forms of obesity exist. Several genetic disorders have been described that lead to early onset monogenic obesity. Leptin (LEP), leptin receptor (LEPR), melanocortin 4 receptor (MC4R), proprotein converting protein subtilisin / kexin-type 1 (PCSK1) and proopiomelanocortin (POMC) are the genetic mutations that have been most frequently shown to cause mono...

A Novel Inactivating Compound Heterozygous Mutation in KISS1R/GPR54: Cases of Three Siblings

Nalbantoglu Ozlem , Arslan Gulcin , Koprulu Ozge , Hazan Fılız , Gursoy Semra , Ozkan Behzat

Introduction: Kisspeptin is a neuropeptide, encoded by the KISS1 gene, which acts upstream of gonadotropin-releasing hormone (GnRH) neurons and also has a critical role for maturation and function of the reproductive axis. Inactivating mutations of its receptor (KISS1R) cause normosmic isolated hypogonadotropic hypogonadism (IHH). In this report, we aim to present three siblings who have IHH due to novel compound heterozygous KISS1R mutation.Cas...

Background: Screen (TV, tablet, smartphones, internet, video games, PC etc.) addiction is a growing problem in child health. The effect on insulin-glucose metabolism is not well known yet.Objective and hypotheses: To investigate the insulin resistance in screen addicted children.Method: We studied 108 children and adolescents aged 13.72±1.95 years (range 11–17 years). Participants were divided into three groups according ...

Koprulu Ozge , Acar Sezer , Nalbantoglu Ozlem , Kirbiyik Ozgur , Arslan Gulcin , Ozkaya Beyhan , Ozdemir Taha Resid , Ozkan Behzat

Introduction: Congenital adrenal hypoplasia, a rare cause of childhood primer adrenal insufficiency, is caused by defects in transcription factors involved in the development of adrenal gland. One of them is the NROB1 (DAX1) gene, localized in Xp21.2. DAX1 mutations have been identified that cause X-linked adrenal hypoplasia congenita. Infants affected with X-linked adrenal hypoplasia congenita may present with salt-wasting, micropenis or cry...
