It is caused by mutations in the gene encoding delta 8 -delta 7 sterol isomerase emopamil-binding protein EBP and is inherited in an X-linked dominant pattern with variable expressivity, possibly due to different patterns of X chromosome inactivation. What you should be alert for in the history Past medical history is very important for diagnosis if the patient presents later than neonatal period, since some of the clinical features resolve spontaneously as patients grow older. The alerting history includes congenital ichthyosiform erythroderma, systematized follicular atrophoderma, facial anomalies, limb shortening, joint dysfunction, hexadactyly and cataracts.

Ortho-surgical management of a Conradi–Hünermann syndrome patient: rare case report

Alternative titles; symbols. Chondrodysplasia punctata CDP is a clinically and genetically heterogeneous disorder characterized by punctiform calcification of the bones. X-linked dominant CDP, also known as Conradi-Hunermann syndrome, is the most well-characterized form. CDPX2 arises almost exclusively in females and is usually lethal in males. In addition to radiographic stippling, the disorder is characterized by rhizomelic shortness, transient congenital ichthyosis following the lines of Blaschko, patchy alopecia, cataracts, and midface hypoplasia. Affected males are extremely rare and the clinical features in males almost always result from postzygotic mosaicism for an EBP mutation summary by Aughton et al.


Conradi Hünermann Syndrome

Correspondence Address : Dr. Conradi—Hunermann syndrome is a common form of chondrodysplasia punctata, inherited as X-linked dominant disorder of cholesterol metabolism due to mutation of emopamil-binding protein gene resulting in a spectrum of skeletal, cutaneous, and ocular abnormalities. One-day-old premature, cesarean-delivered female neonate admitted with xerotic, featherlike yellow-to-white hyperkeratotic scale all over the body with craniofacial defect, coarse hair, patches of cicatricial alopecia, and absent eyebrows. Baby had rhizomelic shortening of proximal limb, clinodactyly, club foot, talipes equinovarus, and bilateral congenital cataract. Radiological skeletal survey revealed punctate stippled calcification involving left femoral head epiphysis, bilateral tarsal bones, vertebral bodies of multiple thoracolumbar vertebrae, and sternum. Serum level of 8-dehydrocholesterol was elevated.
