TAP1 polymorphism identified in African-American Graves' disease patients.
Polymorphism in transporter associated with antigen processing (TAP)1 gene has been observed in African American Graves' disease patients. Single strand conformational polymorphism has been used to identify variation for the locus. First-strand cDNA was generated from cell lines obtained by Epstein-Barr virus immortalization. Four variant alleles for TAP1 have been observed and the products have been sequenced to compare with the location of observed with SSCP position patterns. Variants were detected and compared with substitutions within TAP1 polypeptide which includes changing valine to leucine and three (3) silent substitutions for glycine, glutamic acid and alanine.
