Background: Fetal skeleton develops early in the fetal period. The appendicular and the axial skeleton undergo a programmed pattern of endochondral ossification, whereas the calvarium and portions of the clavicle and pubic bone ossify via membranous ossification. Disruption of the molecular mechanisms fine-tuning this process leads to osteo-chondrodysplasias (skeletal dysplasias) or dysostoses, namely genetic skeletal disorders. The 2015 revision of the Nosology and Classifica...

Background: Although there is considerable literature dealing with the diagnosis, initial management and early complications of meningococcemia, data about late complications is scarce. Growth plates may be influenced permanently by ischemia leading to late orthopedic complications such as leg length discrepancy, angular deformity and distorted body proportion. We present a patient with disproportionate short stature due to late squeal of meningococcemia who was misdiagnosed a...

Background: Osteogenesis imperfecta type XVII (OI17) (MIM#182120) have been described recently due to mutation in secreted protein, acidic, cysteine-rich (SPARC) gene located on 5q33.1.Objective and hypotheses: Here we report a novel mutation in SPARC causing OI17.Case: Two siblings presented to our clinic at the age of 10.3 and 0.5 years old. Parents were consanguineous. The older one was born with birth weight &...

Introduction: Mutations of the PLS3 gene (MIM 300910), encoding plastin 3, are an extremely rare cause of osteogenesis imperfecta (OI). It has an X-linked inheritance and is characterized by early-onset osteoporosis and kyphosis, which can cause compression fractures, especially in the thoracic vertebrae. Although there are reports showing that bisphosphonates are effective in improving the bone mineral density of patients with PLS3 variants,...

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...
