A Novel Mutation in Steroidogenic Factor Gene in a Patient with 46, XY DSD without Adrenal Insufficiency

Anik Ahmet , Catli Gonul , Abaci Ayhan , Tuhan Hale Unver , Onay Huseyin , Aykut Ayca , Bober Ece

Introduction: Steroidogenic factor-1 (SF1/NR5A1) is a nuclear receptor, which regulates genes that have functions in the development of adrenal glands and gonads, reproduction, and other metabolic functions.Case presentation: A 20-day-old infant was admitted due to ambiguous genitalia. Physical examination revealed a 2×1 cm phallus, bifid scrotum, and hypospadias. Both gonads were palpable in the inguinal canal. Serum levels of adrenal androgens (17...

A Novel Androgen Receptor Gene Mutation in a 46,XY Patient: Complete Androgen Insensitivity Syndrome

Tuhan Hale , Anik Ahmet , Aykut Ayca , Onay Huseyin , Bober Ece , Abaci Ayhan

Background: Androgen insensitivity syndrome is the most common cause of 46,XY disorders of sex development. This condition is inherited in an x-linked recessive pattern and the most common causes are inactivating mutations in the androgen receptor (AR) gene.Objective and hypotheses: In this study, we report a novel AR gene mutation in an adolescent patient presenting with primary amenorrhea.Method: A 16-year-old p...

Thyroid hormone resistance syndrome due to a new mutation in the TRHA gene

Tuhan Hale , Donbaloğlu Zeynep , Kırbıyık Özgür , Parlak Mesut , Demir Korcan

Introduction: Resistance to thyroid hormones is defined as lack of response of peripheral tissues to triiodothyronine (T3) which is the active form of thyroid hormones. In general (85%) a mutation is detected in the thyroid hormone receptor β (THRB) gene and more rarely, the thyroid hormone receptor α (TRHA) gene.Case: A 4.7-year-old boy, was admitted to the pediatric endocrinology outpatient clinic of Akdeniz...

Can asprosin be used as a diagnostic biomarker for non-alcoholic fatty liver disease in obese children?

Tuhan Hale , Singin Berna , Donbaloğlu Zeynep , Özdem Sebahat , Parlak Mesut

Objective: As obesity rates rise among children, non-alcholic fatty liver disease (NAFLD) is becoming more prevalent. Although liver biopsy is considered the gold standard for diagnosing NAFLD, it is an invasive procedure and not practical for screening. Asprosin, a recently unveiled adipokine, is released in response to fasting. In this study, we aim ed to investigate the diagnostic value of asprosin for NAFLD in obese patients....

Donbaloğlu Zeynep , Singin Berna , Acar Sezer , Bedel Aynur , Barsal Çetiner Ebru , Aydin Behram Bilge , Parlak Mesut , Tuhan Hale

Objective: We aimed to evaluate the relation between the peak growth hormone (GH) levels on provocative tests and response to recombinant human GH (rhGH) therapy in patients with GH deficiency (GHD).Methods: This was a cross-sectional, single-center, and retrospective study. A total of 518 patients who received rhGH therapy under the age of 16 in the Endocrinology Clinic of Akdeniz University Hospital between 1997 and 20...

Prenatal Smoke-Exposure is Associated with Increased Anogenital Distance in Female Infants

Özalp Kizilay Deniz , Aydin Cansever , Aygün Ayse , Ünver Tuhan Hale , Olukman Özgür

Background: Cigarette contains more than 4,000 toxins and is suspected of having endocrine-disrupting properties. Anogenital distance (AGD) is an important biomarker of fetal androgen exposure and intrauterine masculinization. There are limited number of studies examining whether AGD is affected by prenatal smoke-exposure. The aim of this study is to investigate the effects of maternal smoking during pregnancy on newborn infants' AGD.<p class="abstext"...
