Mvwf QTL 96.5% Bayes credible intervals. Chromosomes are represented as vertical bars, and ticks represent markers used in mapping. To the left of each chromosome is the 96.5% Bayes credible interval constructed as described.25 To the right of chromosome 10 are the regions with human homology of synteny to significant regions identified in human studies 22q11.1,35 21q22.3, and 12q12.36 JS1415 is a marker derived from a B6/WSB T/G SNP downstream from the Vwf gene (128.3 Mbp) that produces an MspI restriction fragment polymorphism.
