Sly and Rbmy gene copy number correlates with EAE and CVB3 susceptibility among B6–ChrY consomic strains. (A) Gene copy number for each of the consomic strains relative to B6. n ≥ 5 mice per strain. (B) Correlation analysis of gene copy number with the CDS for EAE. (C) Correlation analysis of gene copy number with myocarditis heart score. The x-axis represents the strain origin of ChrY.
