Conradi-Hünermann-Happle syndrome (CDPX2, OMIM 302960) is an inherited X-linked dominant variant of chondrodysplasia punctata which primarily affects the skin, bones and eyes.
Conradi-Hünermann-Happle syndrome (CDPX2, OMIM 302960) is an inherited X-linked dominant variant of chondrodysplasia punctata (CP) caused by mutations in one gene of the distal pathway of cholesterol biosynthesis.
X-linked dominant chondrodysplasia punctata type 2 (CDPX2) is a condition involving facial, skin, and skeletal dysplasia as a result of a mutation in emopamil binding protein (EBP).
Diagnosis of Conradi-Hünermann-Happle syndrome was confirmed by plasma sterol analysis showing markedly elevated levels of 8(9)-cholestenol and 8-dehydrocholesterol and by detection of a missense mutation (c.307G>A; p.E103K) in the emopamil-binding protein gene.

Molecular genetic analysis of the EBP gene revealed a nonsense mutation (c.328C>T, p.R110X), which was previously detected in one CDPX2 patient and in a second female patient, who was only affected on one body side and erroneously diagnosed as CHILD syndrome.
Molecular, biochemical, and phenotypic analysis of a hemizygous male with a severe atypical phenotype for X-linked dominant Conradi-Hunermann-Happle syndrome and a mutation in EBP.
Molecular, biochemical, and phenotypic analysis of a hemizygous male with a severe atypical phenotype for X-linked dominant Conradi-Hunermann-Happle syndrome and a mutation in EBP.
Mutations in EBP have previously been associated with Conradi-Hunermann-Happle syndrome (CHH), an X-linked dominant disorder characterized by skeletal dysplasia, skin, and ocular abnormalities, which is usually lethal in males.
Mutations of the gene coding for emopamil binding protein (EBP) can lead to deficient activity of 3-β-hydroxysteroid Δ(8), Δ(7) isomerase and are most commonly identified in. association with the X-linked dominant (male lethal) chondrodysplasia punctata (CDPX2), also known as Conradi-Hunermann syndrome.
Plasma sterol analysis was a highly specific and sensitive indicator of the presence of an EBP mutation in females with suspected CDPX2, including a clinically unaffected mother of a sporadic case.
