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...

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...

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: 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...

Objectives: Proopiomelanocortin (POMC) is the polypeptide precursor of several peptides including adrenocorticotropic hormone (ACTH), melanocyte stimulating hormone (MSH) and β-endorphin. POMC deficiency is a very rare disease characterized by adrenal insufficiency, early-onset obesity, and pigmentation abnormalities. Here we describe an 18 month old boy with central adrenal insufficiency, hypothyroidism, obesity and fair skin. Genetic analysis revealed a homozygous p.G99...

Background: Hereditary hypophosphatemia (HH), is a rare condition related to decreased renal tubular phosphate reabsorption. Although X-linked hypophosphatemia (PHEX mutation) is the most frequent cause of HH, recent advances in the next-generation sequencing (NGS) techniques enable the identification of various genetic etiologies. Our study aims to determine the molecular etiology of patients with hypophosphatemia and to identify new candidate genes....

Aim: Quail egg (QE) consumption became popular among children for alleged health benefits. Based on our observation of premature thelarche (PT) in a few children who consumed QE, we investigated the relationship between QE and puberty by a clinical and an experimental studies.Method: In the clinical study, a questionaire was used to compare the frequency and amount of QE consumption (between 55 girls with PT (n ...

Background: Raine Syndrome (RS) is characterized by hypophosphatemia and typical facial dysmorphic features. Subperiostal thickening and diffuse generalized osteosclerosis are the most common radiological findings. Biallelic loss of function mutations in FAM20Cgene cause RS and by reduction of the transcription of DMP1 leads to FGF23-related hypophosphatemia. Here we present a new case with RS.Case: A 9-month-ol...

Keywords: children, primary osteoporosis, next-generation sequencingBackground: Primary osteoporosis (POP) is a rare bone fragility disorder of childhood and is mainly related to osteogenesis imperfecta (OI). However, patients without clinical OI features with recurrent long bone and/or vertebral fractures who comply with the osteoporosis criteria are considered to have non-OI POP. Diagnosis and classification of non-OI ...
