Introduction: Vitamin D-dependent rickets (VDDR) describes a group of genetic disorders characterized by early-onset rickets that develops due to insufficient concentration of active forms of vitamin-D or unresponsiveness to active vitamin D. The aim of this study was to share the clinical features and long-term outcome of cases followed up in our center with the diagnosis of either VDDR-Type-1 and VDDR-Type-2.Method: Pr...

Introduction: Barakat syndrome, also known as HDR syndrome (OMIM 146255), is a clinically heterogeneous, rare, autosomal dominant genetic disorder, characterized by the triad of hypoparathyroidism (H), deafness (D), and renal disease (R). The phenotypic features are attributed to mutations of the GATA3 gene, which encodes a transcription factor essential for embryonic development of the parathyroid glands, auditory system, and kidneys. Here, we report...

Introduction: Aggrecan is a major proteoglycan component of the articular and growth plate extracellular matrix, encoded by the ACAN gene (MIM: 155760). Although short stature and various dysmorphic findings are observed in individuals with ACAN mutations, the relationship between genotype and phenotype is not clear.Case: A 6.75-year-old pre-pubertal girl presented with disproportionate short stature. She was full term f...

Introduction: Luscan-Lumish syndrome (LLS) is a postnatal overgrowth syndrome characterized by macrocephaly, mental retardation, seizures, postnatal overgrowth, and developmental delay, caused by a heterozygous mutation in the SETD2 gene on chromosome 3p21, which exhibits autosomal dominant inheritance.Case Report: A ten-year-old girl presented with menarche. She was born to healthy non-consanguineous parents at 37 weeks...

Introduction: Fulminant type 1 diabetes (FT1D) occurs because of a sudden and almost total destruction of pancreatic β-cells, triggered by a viral infection. FT1DM may cause diabetic ketoacidosis (DKA) and even sudden death. Thus prompt diagnosis is vital.Case Report: Antibiotic treatment was started for a 4-year-old female patient because of a fever and cough. On the second day of treatment, she was admitted with r...

The genetic causes of 46, XY disorders of sex development (DSD) are mostly unknown, having been identified in only 20-35%. Mitogen-activated protein kinase 1, part of the MAPK signaling pathway, which controls testicular development, is one of the etiological genetic pathways. Here, we present a case of 46, XY DSD with heterozygous MAP3K1 variant. A 6-month-old baby was referred to pediatric endocrinology because of ambiguous genitalia. They were born by C-section at 28 weeks ...

Background: Although thyroid nodules are rare in children compared to adults, the risk of malignacy is higher. Thyroid fine-needle aspiration (FNA) is a reliable diagnostic method used in the prediction of malignancy in the evaluation of thyroid nodules together with clinical and ultrasonographic findings.Objective and hypotheses: To compare clinical, ultrasonographic, cytological and histopathological findings in patients who underwent FNA.<p class=...

While it has been established that within the first 4 months of life there is an absence of the circadian rhythm guiding cortisol secretion, it remains unclear if a random serum cortisol (rSC) level is useful in diagnosing neonatal primary adrenal insufficiency (PAI). The objective of this study is to determine the utility of rSC in determining PAI within the first 4 months of life. This is a retrospective chart review of subjects who had rSC collection and high dose cosyntrop...

Background: Prohormone convertase is an enzyme that converts many biologically inactive prohormones into biologically active peptides. Its deficiency is characterized by deficiency of variable levels in all the hormone systems. In relation to this, postprandial hypoglycemia has been reported but, a case of prohormone convertase deficiency presenting with a diagnosis Type 2 diabetes mellitus has not been previously reported.Case p...

Stüve-Wiedemann syndrome (SWS) is an autosomal recessive disorder characterized by bowing of the long bones and other skeletal anomalies, neuromuscular abnormalities, dysautonomic symptoms, and respiratory and feeding distress usually resulting in early death.We report a girl, aged 6 years, with SWS. We measured bone mineral density in the lumbar spine, using dual-energy x-ray absorptiometry (DXA) with a densitometer (Hologic). The result is express...
