Abstract
This study was undertaken to determine the genetic control of host susceptibility to coxsackievirus B3 (CVB3)-induced chronic myocarditis in a mouse model. An autosomal recessive autoimmune myocardial disease (amd) gene (possibly more than one gene), which determined susceptibility to CVB3-induced chronic myocarditis in the A/J and DBA/2J inbred mouse strains, was mapped to a segment of chromosome 14. Data from both the AXB/BXA recombinant inbred (RI) strains and the B10.D2(57N) H-8b congenic mice supported this linkage relationship. Analysis of the AXB/BXA RI strain distribution patterns suggested that amd maps distal to the Np-2, Tcrα, and Myhcα loci.
