Introduction: Various types of mutations in GHRHR cause isolated growth hormone deficiency type 1B. Here, we report the clinical features associated with deletion of whole GHRHR gene for the first time.Case: A four-year–and-nine-month-old otherwise healthy girl was admitted due to short stature. She was born at term with a birthweight of 3750 gr. Her height velocity slowed down after 2 years of age. The mother (157.8 cm, −0.8...

Introduction: Aromatase deficiency leading to virilization in mother and female fetuses during pregnancy is a rare disease. It is characterized by impaired estrogen production, increased gonadotropins, and ovarian cysts. Herein, we report a clinical phenotype of the virilized female due to a novel compound heterozygous mutation in CYP19A1.Case report: A 4-month-old girl was referred due to cliteromegaly. Her mother had developed acne, hair loss,...

Circulating C1q Complement/TNF-Related Protein (CTRP)-13 Levels in Obese Children and Its Relationship with Metabolic Disorders

Mert Erbaş Ibrahim , Paketci Ahu , Turan Serkan , Şişman Ali Rıza , Demir Korcan , Bober Ece , Abacı Ayhan ,

Background: C1q/tumor necrosis factor-related proteins (CTRPs) are the recently recognized members of the adipokine family, secreted from adipose tissue. Some types of CTRPs, including CTRP-13, play an important role in energy metabolism in humans. Also, CTRP-13 was found as an anorexigenic factor in experimental studies.Objective: We aimed to investigate serum CTRP-13 levels in obese and healthy children, as well as the...
