Background: Osteogenesis imperfecta (OI) is characterized by low bone mass and bone fragility mainly due to COL1A1/COL1A2 gene defects. However, >17 genes have been identified in the pathogenesis of OI. Here, we aim to characterize genotypic spectrum of our OI cohort.Methods: Forty-nine OI patients (28 males) from 38 different families (13 consanguineous/9 multiplex) were screened with the next-gene...

Background: Hypergonadotropic hypogonadism(HH) in females results from primary gonadal failure related to genetic defects affecting ovarian development and function or acquired gonadal damage; limited knowledge exist regarding underlying genes involved or potential gene X environment interactions responsible for disease trait manifestations. While pathogenic variants in single genes, chromosomal abnormalities such as Turner syndrome and acquired gonadal damage...

Introduction: Short stature is a common manifestation of Noonan syndrome (NS). GH deficiency, GH insensitivity, and neurosecretory dysfunction have been reported in the literature. The optimal GH treatment for NS is still controversial. In this study, we aimed to evaluate the growth characteristics in addition to clinical features of NS, and the growth response to GH treatment by using a nationwide registration system.Material and methods: Children and a...

Background: Paternally expressed mono-allelic pathogenic variants in the MAGEL2 (melanoma antigen L2) gene cause Schaaf-Yang syndrome (SHFYNG), a multisystem disorder with psychomotor delay, intellectual disability, behavioral abnormalities, and obesity. Severity of the disease is highly variable, some patients may die in utero and some can live with moderate disabilities. MAGEL2 gene is located in the 15q11.2– q13 region which includes...

Achieving optimal metabolic control can be extremely challenging in some children and adolescents with T1DM. The adherence to multiple injections/day is among the leading causes of suboptimal control. Recently insulin degludec/aspart co-formulation (70%IDeg+30%IAsp: IDegAsp) has become available. Because of the longer-duration of IDeg, and retained individual pharmacokinetics of IDeg and IAsp, we wanted to test insulin IDegAsp's efficacy in our patients with po...

Objective: Congenital isolated ACTH deficiency (IAD) is a rare autosomal recessive disorder that is characterised by low levels of plasma ACTH and cortisol with normal pituitary structure and hormones. Clinical presentation can occur in the neonatal period, as well as later in childhood. Here, we report a patient with IAD due to a novel TPIT mutation.Case: A 48/12 years old girl presented with loss of concioussness and found to be hypoglycemic...

Objective: Antley-Bixler syndrome Type 1 (ABS1) is a rare form of craniosynostosis characterized by multiple dysmorphic features, radio-humeral synostosis and urogenital abnormalities due to P450 oxidoreductase (POR) gene mutations. ABS is also associated with adrenal and gonadal failure which are sometimes underrecognized due to predominance of skeletal findings in various clinics. We report a female patient with very characteristic skeletal and facial features of AB...

Background: Precocious puberty has a complex and polygenic etiology. To describe genetic factors affecting onset and regulation of puberty and pathophysiology of precocious puberty, further studies are needed. Although, it is reported that ACTH receptor MC4R has impact on premature adrenarche, MC2R is expressed in the adrenal cortex and has a major role on the control of hypothalamo-pituitary-adrenal cortex. Melanocortin signaling system is reported to have l...

Background: Borderline precocious and normal-onset puberty can show slow or fast course. The fast development of pubertal signs can be resulted in decrease in final height (FH) via accelerated growth and bone maturation.Objective and hypotheses: To study the effectiveness of GnRHa in improving FH in girls with advanced bone age (BA) and decreased predicted height (PH) in borderline early or normal physiological puberty.Method: 135 ...

Background: 3-M syndrome is an autosomal recessive growth disorder characterised by severe pre- and post-natal growth retardation caused by mutations in CUL7, OBSL1 or CCDC8. Clinical characteristics include dysmorphic facial features and fleshy prominent heels with a variable degree of radiological abnormalities.Objective and hypotheses: Evaluation of four new patients from two different families. Cases:Family-1/Patients-1,2: Two ...
