A Rare Cause of Primary Ovarian Insufficiency: Novel Homozygous c.2120G>C(p.Arg707Pro) Pathogenic Variant in the MCM8 Gene

Eren Simge , Türkyılmaz Ayberk , Özdemir Mustafa , Uçar Ahmet

Introduction: Primary ovarian insufficiency (POI) is a condition characterized by amenorrhea with elevated FSH and LH levels as a result of ovarian dysfunction. Ovarian failure is a very rare condition in pediatric population. Genetic syndromes (Turner, Fragile X syndrome) or malignancy treatment are the main reasons. The minichromosome maintenance complex component 8 (MCM8) gene is responsible for the repair of DNA double-strand breaks;MCM8 is a rare cause of...

Introduction: 5-Hydroxymethylfurfural (HMF) is formed when sugars like glucose and fructose are heated in the presence of amino acids. HMF is naturally present in many foods and we are exposed to HMF in daily life. There are conflicting data on potential genotoxic, mutagenic, carcinogenic, DNA-damaging, organotoxic and enzyme inhibitory effects of HMF and its metabolites. We aimed to investigate toxic effects of HMF on reproductive system in peripubertal rats....

Arasli Yilmaz Aslihan , Elmaogullari Selin , Demirel Fatma , Tayfun Meltem , Ahmet Ucakturk Seyit , Gurbuz Fatih , Kemal Topaloglu Ali

Background: Maturity-Onset Diabetes of the Young (MODY) is a rare monogenic form of diabetes that result in β-cell dysfunction. MODY accounts for 2–5% of all diabetes cases. We presented here a family with MODY2 caused by a novel heterozygous p.L164I (c.490 C>A) mutation of the GCK gene.Case: A 15,5-year-old girl was admitted to our department because of fasting hyperglycemia. She had no polyuria, polydipsia and weight loss...

Macro TSH- a Rare Cause of High Levels of TSH

Elmaogullari Selin , Yilmaz Aslihan Arasli , Ucakturk Seyit Ahmet , Tayfun Meltem , Gurbuz Fatih , Ucar Fatma , Bulut Erdem , Hattori Naoki , Demirel Fatma

Background: Macro TSH is a high molecule weighed complex with low bioactivity that is comprised of TSH and anti-TSH antibodies. Potentiality of macro TSH should be kept in mind in clinically euthyroid and asymptomatic patients with normal free T4 and T3 levels and relatively high TSH levels. Diagnosis of macro TSH is suspected if polyethylene glycol (PEG) precipitable TSH exceeds %75 and confirmed if high molecule weighed TSH is shown with gel filtration ...
