title: Genetics of dystrophic epicardial mineralization in DBA/2 mice.
abstract: The genetics of dystrophic epicardial mineralization in mice was studied using 6 to 8-week-old hybrids and recombinant inbred strains derived from DBA/2J (high prevalence) and C57B1/6J (low prevalence) mice. DBA/2J mice of both sexes were uniformly affected. No cases were seen among 32 F1 mice and 82 F2 mice. Six out of 31 backcross progeny obtained from F1 females backcrossed to DBA/2J males were affected. Two out of 25 recombinant inbred strains were affected. These results suggest that dystrophic epicardial mineralization is determined by three or four unlinked autosomal recessive alleles.
