Palmoplantar Keratoderma and Erythrokeratoderma v0.86 EBP Zornitza Stark reviewed gene: EBP: Rating: GREEN; Mode of pathogenicity: None; Publications: ; Phenotypes: Chondrodysplasia punctata, X-linked dominant 302960; Mode of inheritance: X-LINKED: hemizygous mutation in males, biallelic mutations in females
Palmoplantar Keratoderma and Erythrokeratoderma v0.86 EBP Zornitza Stark Marked gene: EBP as ready
Palmoplantar Keratoderma and Erythrokeratoderma v0.86 EBP Zornitza Stark Gene: ebp has been classified as Green List (High Evidence).
Palmoplantar Keratoderma and Erythrokeratoderma v0.86 EBP Zornitza Stark Classified gene: EBP as Green List (high evidence)
Palmoplantar Keratoderma and Erythrokeratoderma v0.86 EBP Zornitza Stark Gene: ebp has been classified as Green List (High Evidence).
Palmoplantar Keratoderma and Erythrokeratoderma v0.76 EBP Belinda Chong gene: EBP was added
gene: EBP was added to Palmoplantar Keratoderma and Erythrokeratoderma. Sources: Literature
Mode of inheritance for gene: EBP was set to X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Publications for gene: EBP were set to 10391218; 11038443; 12509714
Phenotypes for gene: EBP were set to Chondrodysplasia punctata, X-linked dominant 302960
Added comment: Multiple unrelated individuals with mutations in the EBP (PMID:10391218, 11038443; 12509714)

Manzke et al. (1980) reported 3 affected girls. Two of their mothers showed a mild form of cicatricial alopecia. The pathognomonic dermatologic findings in the children included erythematous skin changes and striated ichthyosiform hyperkeratosis during the first months of life.

Affected females had typical skin manifestations an all but 1 had skeletal dysplasia. Herman et al. (2002) concluded that 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. No clear genotype/phenotype correlations were ascertained, probably because phenotypic expression is influenced substantially by the pattern of X-inactivation in an affected female.
