Conradi-hunermann Syndrome
Conradi-hunermann syndrome. Clinical test for Chondrodysplasia punctata 2 X-linked dominant offered by Laboratory Genetic Metabolic Diseases. Reports of surviving males both withwithout 47 XXY. Conradi-Hünermann-Happle syndrome or X-linked dominant chondrodysplasia punctata is a rare genetic disorder characterized by skeletal dysplasia stippled epiphyses cataracts transient ichthyosis and atrophic residua in a mosaic pattern.
The format is GTR000000011 with a leading prefix GTR followed by 8 digits a period then 1 or more digits representing the version. National Organization of Rare Disease Web-based medical Description of the clinical featurescharacteristics medical complications and genetics of this condition. Usually lethal in males.
Restricted Growth Association Web-based lay Basic overview of this. Conradi-Hünermann syndrome is a rare genetic condition that is classified in a group of disorders called chondrodysplasia punctata which are all characterized by the formation of small hardened spots of calcium on the tops of the long bones or inside other cartilage in the body. Ultrasound evaluation of long bones.
Punctate epiphyseal calcification is the most characteristic radiological finding with elevation of plasma and tissue sterol level. Molecular analysis confirms the diagnosis by showing the EBP gene mutation. Conradi-Hünermann syndrome kon-rahdē hinĕr-mahn one of the syndromes of chondrodysplasia punctata qv autosomal dominant with variable skin keratinization disorders and facial cardiac optic and central nervous system abnormalities.
The specific symptoms and severity of the disorder may vary greatly from one individual to another. Conradi Hunermann Happle syndrome. Mutations in the gene encoding the emopamil-binding protein have been identified as an underlying cause.
Some characteristics include asymmetric shortening of the upper arm and thigh bones and short stature. Conradi-Hünermann syndrome is characterized by short stature skeletal malformations skin abnormalities and cataracts. X-linked dominant CDP also known as Conradi-Hunermann syndrome is the most well-characterized form.
X linked dominant chondrodysplasia punctata. Other physical abnormalities include small head prominent nose small chin mild joint restriction clinodactyly camptodactyly foot deformities andor undescended testes cryptorchidism in affected males.

Conradi-Hünermann syndrome is a rare genetic disorder characterized by skeletal malformations skin abnormalities cataracts and short stature. Usually lethal in males. It is also commonly associated with disproportionate and asymmetric shortening of long bones upper arms and thigh bones to be specific curvature of the spine and mild to moderate growth deficiency that leads to short stature. Molecular analysis confirms the diagnosis by showing the EBP gene mutation. Reports of surviving males both withwithout 47 XXY. Epiphyseal stippling is also present. Ultrasound evaluation of long bones. Other physical abnormalities include small head prominent nose small chin mild joint restriction clinodactyly camptodactyly foot deformities andor undescended testes cryptorchidism in affected males. Mutations in the gene encoding the emopamil-binding protein have been identified as an underlying cause.
Epiphyseal stippling is also present. ConradiHunermann syndrome is a characterized as a developmental skeletal disorder involving abnormal formation of small hardened calcium areas within the growing ends of long bones. CDPX2 arises almost exclusively in females and is usually lethal in males. Some characteristics include asymmetric shortening of the upper arm and thigh bones and short stature. Conradi-Hünermann syndrome is characterized by short stature skeletal malformations skin abnormalities and cataracts. Bowen-Conradi syndrome is a very rare genetic disorder characterized by growth delays before birth failure to thrive during infancy and malformations of the head and facial area. X-linked dominant CDP also known as Conradi-Hunermann syndrome is the most well-characterized form.
