Genes affected

DSG3 (HGNC:3050): (desmoglein 3) This gene encodes a member of the desmoglein family and cadherin cell adhesion molecule superfamily of proteins. Desmogleins are calcium-binding transmembrane glycoprotein components of desmosomes, cell-cell junctions between epithelial, myocardial, and other cell types. The encoded preproprotein is proteolytically processed to generate the mature glycoprotein. This gene is present in a gene cluster with other desmoglein gene family members on chromosome 18. The encoded protein has been identified as the autoantigen of the autoimmune blistering disease pemphigus vulgaris. [provided by RefSeq, Jan 2016]

DSG3 Gene-Disease associations (from GenCC):

• blistering, acantholytic, of oral and laryngeal mucosa

  Inheritance: Unknown, AR Classification: MODERATE, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), G2P

ACMG classification
