Clinical and genetic heterogeneity of hypochondroplasia.
Hypochondroplasia (HCH) is an autosomal dominant condition characterised by short stature, micromelia, and lumbar lordosis. In a series of 29 HCH probands (13 sporadic cases, 16 familial cases), we tested their DNA for the N540K recurrent mutation previously described in the proximal tyrosine kinase domain of the FGFR3 gene on chromosome 4p16.3, and we detected this mutation in 21/29 HCH patien...
متن کامل[Osteogenesis imperfecta: clinical and genetic heterogeneity].
Osteogenesis imperfecta is a hereditary connective tissue disorder characterized primarily by fractures with no or small causal antecedent; in most patients this is a consequence of diminished or abnormal production of collagen type I. It is a clinically heterogeneous disorder: it has been proposed recently to classify osteogenesis imperfecta in types I-V on the basis of the clinical picture an...
متن کاملClinical and genetic heterogeneity in laminopathies.
Mutations in the LMNA gene encoding lamins A/C are responsible for more than ten different disorders called laminopathies which affect various tissues in an isolated (striated muscle, adipose tissue or peripheral nerve) or systemic (premature aging syndromes) fashion. Overlapping phenotypes are also observed. Associated with this wide clinical variability, there is also a large genetic heteroge...
متن کاملAchondroplasia and hypochondroplasia. Clinical variation and spinal stenosis.
Forty-eight patients with achondroplasia and 24 with hypochondroplasia have been reviewed in order to clarify the differences between the two disorders and establish the height, body proportions and other clinical and radiological variations within each group. Some of the "classical" findings in achondroplasia are not always present, and hypochondroplasia at its most severe is indistinguishable...
متن کاملClinical and genetic heterogeneity of the Joubert and Meckel syndromes
Introduction Identification of genes causing inherited cystic kidney diseases has triggered a major interest for the concept of ‘ciliopathies’. Indeed, almost all of the proteins involved in human renal cystic diseases are expressed in the primary cilium complex located in renal epithelial cells. Primary cilia are cellular extensions containing a microtubulebased axoneme covered by a specialize...
