PMID- 8851724 OWN - NLM STAT- MEDLINE DCOM- 19961205 LR - 20190826 IS - 0001-2815 (Print) IS - 0001-2815 (Linking) VI - 47 IP - 2 DP - 1996 Feb TI - The human leukocyte antigen TAP2 gene defines the centromeric limit of melanoma susceptibility on chromosome 6p. PG - 117-21 AB - A single human leukocyte antigen (HLA) class II allele, DQB1*0301, is strongly associated with melanoma, and the HLA-DR locus provides the telomeric boundary for melanoma susceptibility in the HLA class II region of chromosome 6. However, the centromeric boundary is unknown. This study was designed to determine whether the adjacent upstream transporter associated with antigen processing (TAP) locus, TAP2, constitutes the centromeric boundary of disease susceptibility in melanoma. Molecular oligotyping of TAP2 genes was performed for 36 Caucasian patients with melanoma and for 32 Caucasian control individuals by both amplification refractory mutation system (ARMS) polymerase chain reaction (PCR) and PCR-sequence-specific oligonucleotide (SSO) typing. TAP2 allele frequencies in the melanoma patients were compared to those in non-melanoma Caucasian control populations, and to HLA-DQ allele frequencies determined by molecular oligotyping. While HLA-DQB1*0301 was more common in this group of 36 melanoma patients compared to a group of 200 controls (56 percent vs. 27 percent, Bonferoni-corrected chi-square p < = 0.01), no significant differences were observed in TAP2 allele frequencies between melanoma patients and controls. The TAP2 locus represents the centromeric boundary of disease susceptibility for melanoma in the class II region of chromosome 6p. These results support an etiologic role for HLA-DQB1*0301 in melanoma susceptibility.
