Introduction: Congenital disorder of glycosylation type-1a is a multi-system disease involving neurological, gastrointestinal, ophthalmologic, cardiac or endocrine systems. In addition to hypothyroidism and hypergonadotropic hypogonadism, rare occurrences of hyperinsulinemic hypoglycemia in CDG patients have been reported. In the present report, we describe a patient diagnosed with CDG type-1a accompanied by hyperinsulinemic hypoglycemia, and whose responsive to diazoxide....

Background: 3β-hydroxysteroid dehydrogenase (3βHSD) deficiency is a rare form of congenital adrenal hyperplasia (CAH) and caused by loss of function mutations in the HSD3B2 gene. In classic form, affected patients have salt wasting early in infancy and may have ambiguous genitalia in both sexes. Herein we report a nonvirilized female patient with classic form of 3βHSD deficiency due to homozygous S218P mutation in the HSD3B2 gene and classic phenylketonuria....

Objectives: Trichorinophalangeal syndrome (TRPS) is a cause of syndromic short stature; and is characterized by typical dysmorphology, ectodermal dysplasia, and skeletal findings. There are two types of TRPS; TRPS-I caused by monoallelic pathogenic variants in the TRPS1 gene, and TRPS-II caused by whole gene deletion. TRPS-II; also called Langer-Giedion Syndrome (LGS), in which multiple exocytoses can be seen in addition to typical TRPS features due t...

Introduction: Juvenile Paget's Disease(JPD) is an extremely rare disease of bone characterized by progressive painful bone deformities, fractures and increased bone turnover. Findings also include deafness, loss of vision, vascular calcification and aneurysm. Here, we report two siblings presented with recurrent fractures and diagnosed as JPD by very high alkaline phosphatase levels and radiographic findings. A novel homozygous mutation in the TNFRSF11B g...

Introduction: Subclinical hypothyroidism (SH) is reported up to 20% of obese population and thyroid hormone replacement in these individuals are controversial. In this study, we aimed to determine the effect of thyroid hormones on basal metabolic rate (BMR) in obesity and, thyroid hormone replacement on BMH and weight in obese patients with SH.Method: The study was conducted in 31 obese children (15 of them had subclinical hypothyroidism) admitted to our...

Background: Steroid 5α-reductase catalyzes the conversion of testosterone into the more active androgen, dihydrotestosterone (DHT). In 46, XY patients with recessive mutations in steroid 5α-reductase type 2 enzyme (SRD5A2) gene, the degree of ambiguity ranges from isolated hypospadias to severe undermasculinization. SRD5A2 gene is located on chromosome 2 (p23 region) and is comprised of five exons and four introns.Objective and hypotheses: Mult...

Background: Low-dose adrenocorticotropic hormone stimulation test (LDST) is commonly used for evaluating the adequacy of hypothalamo-pituitary-adrenal axis functions. However, there is still no standardization between protocols used in different centres.Objective: To contribute to the optimal time of highest cortisol response in the LDST in children.Design: A prospective study of L...

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...
