MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the plakin family of proteins that forms a component of desmosomes and the epidermal cornified envelope. This gene is located in the tylosis oesophageal cancer locus on chromosome 17q25, and its deletion is associated with both familial and sporadic forms of oesophageal squamous cell carcinoma. Patients suffering from the autoimmune mucocutaneous disorder, paraneoplastic pemphigus, develop antibodies against the encoded protein. [provided by RefSeq, Jul 2016]
PHENOTYPE: Mice homozygous for a targeted deletion of this gene are viable and fertile. Surprisingly, cornified envelope assembly is not inhibited and adult homozygotes show no obvious pathological phenotype in skin or other epithelia, despite a slight delay in barrier acquisition during embryonic development.

Nature of Mutation
DNA sequencing using the SOLiD technique identified a C to A transversion at position 6123 of the Evpl transcript in exon 22 of 22 total exons. The mutated nucleotide causes a leucine to proline substitution at amino acid 2010 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
The Evpl gene encodes a 2035 amino acid protein that is a component of the cornified envelope of keratinocytes, and may link the cornified envelope to desmosomes and intermediate filaments. The protein can form homodimers or heterodimers with periplakin (PPL), and contains seven plectin repeats and one spectrin repeat (Uniprot Q9D952).
 
The L2010P change falls within a globular region of the protein just outside of the seventh plectin repeat, and is predicted to be possibly damaging by the PolyPhen program.
