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...

Introduction: Autoimmune polyendocrinopathy, candidiasis and ectodermal dystrophy (APECED) is a rare hereditary disorder with autoimmun manifestations affecting both endocrine and non-endocrine tissues. It is caused by mutations in the autoimmune regulatory (AIRE) gene which is defined by the presence of two of the three major components: Chronic mucocutaneous candidiasis, autoimmune hypoparathyroidism and AddisonÂ’s disease. Clinical manifestations may be developed during...

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...

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...
