Hyperinsulinemic hypoglycemia due to biallelic mutations in the DNAJC3 gene

Gurpinar Tosun Busra , Menevse Tuba Seven , Esen Nisa , Turan Serap , Yesilyurt Ahmet , Guran Tulay , Bereket Abdullah ,

Background: DNAJC3 is an endoplasmic reticulum (ER) co-chaperone involved in folding/processing of secretory and transmembrane proteins. The defect in the ER co-chaperone proteins impairs adaptive ER responses and leads to apoptosis, impairment of organ function with multisystemic involvement. Biallelic mutations in the DNAJC3, described in a limited number of cases cause multiple endocrine dysfunction and neurodegeneration of nervous system.<p cl...

Is Type 1 Diabetes Mellitus Predictable? Investigation of Predictive Markers n Siblings of Probands with Newly Diagnosed Type 1 Diabetes Mellitus

Albayrak Serpil , Karaoglan Murat , Yıldırım Ahmet , Keskin Mehmet ,

Background/Aim: Type 1 diabetes Mellitus (T1DM) often presents with clear clinical signs after a long-term asymptomatic autoimmune process. This long and silent period has been leading to an increase in awareness day by day in order to prevent and predict the development of the disease. Among the well-known genetic and environmental risk factors, close relatives of the index cases constitute a population that is quite suitable for predicting and preventing the...

Rahman Syndrome: Hypopituitarism might be responsible for changing height pattern

Betul Kaygusuz Sare , Turan Serap , Esen Nisa , Bereket Abdullah , Yesilyurt Ahmet , Guran Tulay ,

Objective: Histones have important structural and regulatory roles mediating the dynamic packaging of DNA. The dysregulation of histone modification leads to overgrowth syndromes, such as Sotos and Weaver syndrome. Recently heterozygous variants in HIST1H1E, which encodes linker histone H 1.4 has been associated with Rahman Syndrome, which is characterized by a very rare complex phenotype consisting of overgrowth, dysmorphism, and intellectual disabil...

Evaluation Of The Growth Hormone-Insulin like Growth Factor1 Axis And Serum Fibroblast Growth Factor 21 Levels As Related To Stature In Children And Adolescents With Coeliac Disease Adherent To Gluten Free Diet

Kaya Fırat , Urgancı Nafiye , Merve Usta Ayşe , Çelik Sedanur , Uçar Ahmet

Background: Coeliac disease(CD)is a common cause of stunted growth. Despite adherence to gluten-free diet(GFD), short stature may persist in some patients with CD. Studies investigating the growth hormone(GH)-insulin like growth factor-1(IGF1) axis in children and adolescents withCDare scant and inconclusive. Fibroblast growth factor-21(FGF-21)is a181amino acid polypeptide that plays a role in growth, lipid and glucose metabolism. The inhibitory effects of FGF...

A Case with Alstrom Syndrome with a Novel Pathogenic Variant In ALMS1 gene as a Rare Cause of Diabetes Mellitus

Dağdeviren Çakır Aydilek , Gizem Bolaç Özyılmaz Leyla , Uçar Ahmet

Introduction: Alstrom syndrome (ALMS) is an autosomal recessive disorder characterized by multiple organ involvement, including progressive cone-rod dystrophy, sensorineural hearing loss, childhood obesity, and type 2 diabetes mellitus. Pathogenic variants in the ALMS1 gene are the known cause for the occurrence of this devastating condition. Here, we reported a case of Alstrom syndrome with a novel homozygous variant in the ALMS gene, who presented to our cli...

Single Gene Variations in Etiology in Children with Severe Obesity

Kahveci Ahmet , Kelestemur Elif , Kurt Ilknur , Guran Tulay , Turan Serap , Bereket Abdullah , Haliloglu Belma

Background: Obesity is a multifactorial disease caused by environmental and genetic factors. Single gene defects explain approximately 5-13% of early-onset obesity and these rates vary according to genetic panel used and the rate of consanguinity in the population studied. As the new treatment modalities emerge for monogenic obesity, it is important to identify the molecular etiology of obesity.Materials and Methods: Buc...

A rare cause of hypogonadotropic hypogonadism: KLB gene variant in a prepubertal boy evaluated for micropenis

Yavas Abali Zehra , Yesilyurt Ahmet , Demircioglu Serap , Guran Tulay , Haliloglu Belma , Bereket Abdullah

Background: Micropenis may have various causes, like hormonal imbalances during fetal development, disorders affecting hormone production/action, and genetic factors. Determining the etiology may be challenging, especially in isolated cases and a thorough medical evaluation is typically necessary. The identification of genetic etiology is facilitated by the wide use of next-generation sequencing technologies. Here we report a patient presented with micropenis ...

Tibial-tubercle avulsion and patellar-tendon rupture in an adolescent with osteogenesis imperfecta

Şen Küçük Kübra , Çullu Emre , Anık Ahmet

Introduction: Osteogenesis imperfecta (OI) is a genetic disorder affecting connective tissue, characterized by decreased bone density, spontaneous fractures, and non-bone manifestations including dental anomalies, blue sclerae, hearing impairment, and joint hypermobility. While tendon ruptures are commonly associated with various systemic conditions, occurrences related to OI are less frequent. Patellar tendon (PT) rupture, particularly, is exceptionally uncom...

A rare metabolic disease mimicking starvation hypoglycemia: fructose 1-6 bisphosphatase deficiency

Güneş Sebla , Göksoy Emine , Öztürk Selvin , Manav Zehra , Anık Ahmet

Introduction: Diagnosing hypoglycemia-associated metabolic disorders is challenging and necessitates a methodical approach. Unlike idiopathic ketotic hypoglycemia (starvation hypoglycemia), fructose 1,6-bisphosphatase deficiency is an uncommon metabolic disorder characterized by a defect in gluconeogenesis. This disorder also causes lactic acidosis, hypertriglyceridemia, hyperuricemia, and ketonuria. This case report describes two siblings diagnosed with fruct...
