Background: Desert Hedgehog (DHH) gene acts on early testicu-lar development, testis cord formation and differentiation of fetal Leydig cells. It also has a role in nerve sheath formation. DHH gene mu-tations is a very rare cause of 46,XY gonadal dysgenesis (GD). Gonadal tumors and peripheral neuropathy have been associated with DHH mutations.Aim: To present three patients with 46,XY GD due to novel homozygous DHH muta...

Background: 17β-Hydroxysteroid Dehydrogenase3 (17b-HSD3) deficiency is a rare autosomal recessive disorder, caused by a mutation of the HSD17B3 gene. The phenotypic spectrum ranges from normal-appearing female external genitalia to microphallus with hypospadias and variable degrees of genital ambiguity. 17b-HSD3 deficiency phenotype is variable, leading to misdiagnosis especially with partial androgen insensitivity syndrome and 5alfa reductase deficiency.<p c...

Background: Nonclassical congenital adrenal hyperplasia (NCAH), which is generally presented with symptoms of androgen excess, is inherited autosomal recessive due to different kind of mutations in the CYP21A2. Recently, high frequency of copy number variations at CYP21A2 gene and predisposition of heterozygous duplicated CYP21A2 for de novo gene aberrations has been reported.Objective and hypotheses: To evaluate clini...

Background: Main diagnosis of 46,XY disorders of sex development (DSD) with normal testosterone secretion Androgen insensivity sydrome (AIS) or 5α-reductase deficiency (5α-RD). In prepubertal period, AIS and 5α-RD present indistinguishable phenotypes that necessitate the molecular analyses for the definitive diagnosis.Objective and hypotheses: Clinical, hormonal and genetic investigation of 46,XY DSD patients who considered as PAIS or 5&#9...

Introduction: SOFT-syndrome (#MIM 614783) is a rare condition characterized by short stature, onychodysplasia, facial dysmorphism and hypotrichosis caused by POC1A gene mutations. Moreover, severe insulin resistance (IR) and metabolic disorders may also accompany. Hereby, we report two-patients with SOFT-syndrome, who had severe short stature and IR, with a novel POC1A mutation.Case Report: Patient 1 (P1), a 16-month ol...

Evaluation of clinical outcomes in children and adolescents with type 1 diabetes switching from Insulin Glargin to Insulin Detemir

Turan Hande , Kaya Didem , Ercan Oya

Basal-bolus insulin therapy is currently, the most common treatment modality in children and adolescents with type 1 diabetes mellitus (T1DM) worldwide. Insulin glargine and detemir are two different molecules, produced with small modifications, of human insulin. In this prospective longitudinal study, we aimed to compare HbA1c, time in range in CGM, basal insulin doses and hypoglyccemia frequencies in children and adolescents with T1DM who underwent switching from insulin det...

Background: Deficiency of one or more pituitary hormones, often with growth hormone (GH) deficiency, is defined as multiple pituitary hormone deficiencies (MPHD) or congenital hypopituitarism (CH). CH cases are mostly sporadic and have a prevalence of 1/3000-4000 live births. There are many known and yet unknown molecular pathways explaining the complex structure and functions of the pituitary gland. Many different gross and small sequence variants in the gene...

Introduction: Short stature is a multifactorial condition caused by both genetic and environmental factors. Genetic causes include chromosomal disorders and diseases inherited by monogenic and multifactorial inheritance. The purpose of genetic evaluation in short stature is not only for diagnosis, but also to provide additional information to the patients and their families about prognosis of the disease, treatment approaches and genetic counseling.<p clas...
