Common swine leucocyte antigen (SLA) haplotypes in NIH and Sinclair miniature swine have similar effects on the expression of an inherited melanoma
Abstract
Mixed lymphocyte culture and serological typing of NIH and Sinclair miniature swine indicate that the two herds share a common SLA haplotype. NIH haplotype a (International Haplotype H10) appears identical to Sinclair haplotype B, which has significant effects on the penetrance of Sinclair swine cutaneous malignant melanoma (SSCM). Offspring of crosses between melanoma-bearing Sinclair swine homozygous for the B haplotype and non-melanoma NIH aa swine have tumour incidence identical to Sinclair melanoma BB x Sinclair non-melanoma BB offspring. Our results provide further support for the involvement of the swine leucocyte antigen (SLA) complex in the inheritance of SSCM, and identify a new source of non-tumour animals that have all of the genes for SSCM except those at the tumour-initiator locus.
