Two factors, is classification and its immunogenetics, may have contributed to an incomplete understanding of the pathogenic mechanism in the disease group commonly termed 'cicatricial pemphigoid'. We have previously demonstrated that pure ocular cicatricial pemphigoid (OCP) is a unique clinical and immunopathological entity. In an effort to better define the immunogenetic characteristics for patients with pure OCP, we performed HLA typing for the class II MHC gene HLA-DQB1*0301 allele, by amplifying genomic DNA extracted from patients with polymerase chain reaction, followed by hybridization with a sequence-specific oligonucleotide probe on dot-blotted and Southern-blotted amplified DNA samples. Ninety percent (9/10) of patients with pure OCP had the DQB1*0301 allele, in contrast to 52% (17/33) of normal individuals who had the DQB1*0301 allele. The high frequency of the HLA-DQB1*0301 allele in patients with pure OCP may point to a distinct immunogenetic pattern and possibly a distinct pathomechanism for the disease.

UI	MeSH Term	Description	Entries
D010390	Pemphigoid, Benign Mucous Membrane	A chronic blistering disease with predilection for mucous membranes and less frequently the skin, and with a tendency to scarring. It is sometimes called ocular pemphigoid because of conjunctival mucous membrane involvement.

D006683	HLA-DQ Antigens	A group of the D-related HLA antigens found to differ from the DR antigens in genetic locus and therefore inheritance. These antigens are polymorphic glycoproteins comprising alpha and beta chains and are found on lymphoid and other cells, often associated with certain diseases.
