Genes affected

EVPL (HGNC:3503): (envoplakin) 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]

The c.5785G>A (p.E1929K) alteration is located in exon 22 (coding exon 22) of the EVPL gene. This alteration results from a G to A substitution at nucleotide position 5785, causing the glutamic acid (E) at amino acid position 1929 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
