Background: N-methyl-D-aspartate receptors (NMDARs) are ionotropic glutamate receptors that are widely expressed in the CNS where they play an important role in neurotransmission and cell viability and serve as drug targets for the treatment of neurodegenerative disorders.Objective and hypotheses: Much less is known about the role of pancreatic NMDARs. Since neurons and pancreatic islets have many features in common, we hypothesiz...

Sick euthyroid syndrome (SES) is the most common endocrine disorder in critically ill patients. It has been shown that the decrease in T4 levels correlates with disease severity and prognosis. Whether SES is a compensatory response to the disease course or needs to be treated is not known yet. To our knowledge, there are only a few studies oncritically ill infants and children investigating the correlation between thyroid function and disease severity as well as its outcome. T...

Background: Persistent Müllerian Duct Syndrome (PMDS) needs to be considered in boys (46, XY) presenting with bilateral cryptorchidism or unilateral cryptorchidism associated with an inguinal hernia. Anti-Müllerian hormone (AMH) gene as well as Anti-Müllerian hormone Receptor (AMHR 2) gene mutations have been identified in PMDS boys.Aim and methods: To report a novel mutation in the AMHR 2 gene in monochorionic d...

Background: Marfan syndrome is an autosomal dominant genetic disorder with skeletal, cardiac, and ocular involvement. Mutations in the fibrillin-1 gene on chromosome 15 are responsible for the development of the syndrome.Objective: To present one case of neonatal Marfan syndrome.Case: The patient was a 1-day-old female neonate who was born at 36 weeks gestation via normal delivery. Her body weight was 2900 g and height 48 cm. Ultra...

Background: Endocrine disorders associated with tall stature in childhood are frequently evaluated by Pediatric Endocrinologists. The most common non-endocrine genetic cause of tall stature, Marfan syndrome, is a rare autosomal dominant genetic condition of the connective tissue, which presents with specific dysmorphic features, including thin physique, long extremities and normal growth rate. Little is known regarding the association of Marfan syndrome with o...

Background: Marfan syndrome is one of the most common over-growth conditions and the cardinal features occur in ocular, skeletal and cardiovascular systems. Clinical variation is common and signs are age-dependent.Case: A 9-year-old girl was referred to our pediatric endocrinology clinic for tall stature. Physical examination revealed a lens dislocation with strabismus, high palate, positive wrist and thumb signs, joint hypermobility, and pes plenus. Dil...

Background: Patients with Marfan syndrome (MFS) presents with primary skeletal manifestations such as tall stature, chest wall abnormality, and scoliosis. And these primary skeletal manifestations affect the growth pattern in MFS. Therefore, it is not appropriate to use normal growth charts to evaluate the growth status of MFS.Objective and hypotheses: We aimed to develop disease-specific growth charts for Korean MFS patients and to use these growth char...

Background: Marfan syndrome (MFS) is an autosomal dominant disorder of connective tissue. Cardinal features affect cardiovascular system, eyes and skeleton. It is caused by mutations of FBN1 gene, which encodes the extracellular matrix protein fibrillin 1. The improper activation of TGFβ, due to defective fibrillin-1, is the pathophysiological mechanism. The altered modulation leads to overgrowth of long bones (disproportionate stature) and altered bone morphology.<p ...

Introduction: Marfan syndrome is an autosomal dominant disorder due to a mutation of the FBN1 gene of chromosome 15 that produces fibrillin, a connective tissue protein. Tall stature can be of a major concern especially in a girl patient. Here we discuss a case of a 13-year-old girl with MFS with tall stature and multiple associated comorbidities that pose challenges in her management for the whole family.Case Report: A ...

Background: Prader–Willi syndrome (PWS) is caused by absence of expression of imprinted genes on the paternal chromosome 15 (15q11.2–q13) due to a paternal deletion, maternal uniparental disomy 15 and rarely an imprinting defect. The clinical signs of PWS are hypotonia, muscle weakness, excessive eating, morbid obesity, delayed global development, hypogonadism, and short stature. Marfan syndrome is caused by mutations in the FBN1 gene, located on chromosome ...
