Introduction: Differential diagnosis of thyroid hormone resistance (beta) and TSHoma should be made in patients with high free thyroxine (f-T4) and free triiodothyronine (f-T3) and non-suppressed thyroid stimulating hormone (TSH) levels. The aim of this study was to present the results of etiological research in a patient with Down syndrome who was clinically euthyroid and had high levels of f-T4, f-T3, normal TSH levels.Case</st...

PTEN Hamartoma Tumor Syndrome (Overlap of Cowden syndrome and the Bannayan-Riley-Ruvalcaba Syndrome): Case Report

Manyas Hayrullah , Çatli Gönül , Eroglu Filibeli Berna , Ayranci Ilkay , Özdemir Taha Resid , Dündar Bumin Nuri

Introduction: PTEN Hamartoma Tumor Syndrome (PHTS) is a rare disease with dominant inheritance characterized by benign (hamartoma) and malignant tumors (breast, endometrium, thyroid). Mutations in the tumor suppressor gene phosphatase and tensin homologue (PTEN) gene are responsible for the etiology.Objective: In this case report, we present an 11-year-old male who was being monitored due to follicular thyroid cancer, an...

Filibeli Berna Eroglu , Çatli Gönül , Manyas Hayrullah , Ayranci Ilkay , Kaya Özge Özer , Dündar Bumin

Introduction: An activating mutations in the ABCC8 gene cause both transient and permanent neonatal diabetes mellitus (DM) or MODY 12. In relation to the variant in the ABCC8 gene, patients may also present with either neonatal hyperinsulinism and/or DM later in life. Besides, the same variant can cause different phenotypic features among family members. Response to the sulfonylurea treatment may vary between patients.<...

Introduction: Heterozygous loss-of-function mutations in the glucokinase (GCK) gene cause MODY 2. Conversely, homozygous loss-of-function mutations in the same gene give rise to permanent neonatal diabetes mellitus (DM). Previously, two patients diagnosed with DM in adolescence and had homozygous GCK mutations were reported. Variants in these patients have been shown to exhibit inactivated kinetics that are indistinguishable from neonatal ons...

Results: Total of 47 obese patients (20 females, 39 pubertals, mean age of 14.3 years).±3.2 years) were included in the study. Severe obesity present in 85% of patients, early-onset obesity in 51%, consanguinity among parents in 17%, and at least one parent with obesity in 63.8% were present. 55.3% of the patients had a family history of diabetes, 63% had acanthosis nigricans and 77% had striae. Anthropometric and laboratory ch...

Ayranci Ilkay , Çatli Gönül , Eroğlu Filibeli Berna , Manyas Hayrullah , Bekir Kutbay Yaşar , Koç Altuğ , Nuri Dündar Bumin

Introduction Objective: The SHOX gene is located in pseudoautosomal region of chromosomes of Xp22.33 and Yp11.32. It plays role in proliferation and differentiation of epiphyseal chondrocyte. Leri-Weill syndrome is observed with loss of an allele, while missense mutations lead to idiopathic short stature without any dysmorphic findings. This report presents clinical features of three cases diagnosed with Leri-Weill syndrome, and their responses to rhGH treatme...
