Aykut Ayca , Ozen Samim , Goksen Damla , Onay Huseyin , Atik Tahir , Darcan Şukran , Ozkinay Ferda

Background: The melanocortin-4-receptor gene (MC4R) is a key regulator of energy homeostasis, food intake and body weight which has intensively been analyzed in molecular genetic obesity research. MC4R dysfunction in humans causes hyperphagia, impaired satiety and obesity.Objective and hypotheses: To identify MC4R mutations prevelance in Turkish obese children and adolescents.Method: Ninenty three pediatric and adolescent patients ...

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...

"Steroidogenic Factor-1" (SF-1); It is encoded by the NR5A1 gene in 9q 33.3 and regulates the transcription of genes involved in steroidogenesis. It is reported that 46 of the variants in this gene constitute 10-20% of XY sex development disorders (DSD). The patient admitted because of a swelling in the left groin at one month old. She was raised as female. Uterus was 12x2.5 mm in ultrasonography and the gonad in the inguinal region was evaluated as testis. She was P...

Introduction: Childhood obesity has been associated with many physical and mental health problems.A significant relationship has been reported between psychiatric disorders, especially attention deficit hyperactivity disorder(ADHD) in obese patients due to the melanocortin 4 receptor(MC4R) gene variant, and it has been claimed that these two conditions may share common molecular pathways. However, studies on this subject are quite insufficient.<p class="ab...

Keywords: diabetes, MODY, atypicalIntroduction: Type 1 Diabetes (T1D) is the most common cause of diabetes in childhood, but Type 2 Diabetes (T2D) and monogenic diabetes has attracted increasing attention recently. Cases with atypical diabetes may be challenging for diagnosis, treatment and follow-up management. The purpose of this study was to present the characteristics of atypical diabetes cases from a tertiary referr...
