Introduction: ‘Receptor tyrosine kinase-like orphan receptor 2 (ROR2)’ is a transmembrane protein tyrosine kinase encoded by the ROR2 gene. Pathogenic mutations in ROR2 are involved in two diseases: biallelic loss-of-function mutations in Robinow syndrome and monoallelic gain-of-function mutations in brachydactyly type B1. Recently, monoallelic loss-of-function mutations in ROR2 have been reported as a cause of isolated short stature. Here we repor...

Introduction: Silver-Russell syndrome (SRS) is a rare, well-defined genetic disease characterized by intrauterine and postnatal growth retardation, short stature, triangular face, relative macrocephaly and body asymmetry. The most common molecular pathologies are loss of methylation (50%) of the imprinting center in the p15.5 region of the paternal 11th chromosome and maternal uniparental disomy of the 7th chromosome (5-10%). The IGF2 (insulin-like growth fact...

Introduction: Primrose syndrome was defined in 1982. It is characterized by characteristic facial appearance, macrocephaly, global developmental delay, intellectualdisability and calcification in the outer ear. It occurs with loss-of-function mutations in the ZBTB20-gene. This gene is a transcriptional gene suppressor regulator and is effective on neurogenesis, glucose homeostasis, and postnatal growth. Here, a case with Primrose syndrome will be presented.</p...

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...

Introduction: Patients with homozygous familial hypercholesterolemia (HoFH) suffer from this disorder from birth and they have abnormally high cholesterol levels due to a disease that has autosomal dominant inheritance of genetic aberrations in the coding region for low density lipoprotein receptors (LDLR) in more than 90% of cases, other gene defect includes mutations in apolipoprotein B100 (apoB100) and proprotein convertase subtilisin/kexin type 9 (PCSK...

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...

Objectives: Spondyloenchondrodysplasia with immune dysregulation (SPENCDI) is an immunoosseous dysplasia combining the typical metaphyseal and vertebral bone lesions with immune dysfunction and neurologic involvement which is caused by mutations in ACP5 gene encoding tartrate resistant acid phosphatase 5. Here, we report a three year old girl presented with primary hypothyroidism, developmental delay and thrombocytopenia and diagnosed as SPENCDI.<p class="abstext"...

Objective: Congenital isolated thyrotropin (TSH) deficiency is a rare condition due to autosomal recessive defects in TSHβ, TBL1X, IGSF1, TRHR genes. There are a few patients described with TSHβ mutations to date. These patients display the typical manifestations of severe untreated congenital hypothyroidism. Most patients are unrecognized, even in newborns screening settings due to unelevated TSH levels, which results in severe growth fail...

Background: β-hCG secreting germ-cell tumors (β-hCG-ST) are rare causes of Peripheral precocious puberty (PPP) in boys and usually located in intracranial region. Liver, retroperitoneum, testis and mediastinal cavity are the other localizations reflecting embryonic germ cell sites.Objective and hypotheses: We present a patient with PPP due to elevated β-hCG levels, but extensive efforts to find the source of elevated β-hCG was unrevea...
