Notes

Mapping and Phenotype information for this QTL, its variants and associated markers

J:91685

Linkage analysis was performed on 301 (MRL/MpJ x CAST/EiJ)F2 intercross animals to identify QTLs associated with wound healing. Ear hole punch was inflicted on 6 week old animals and wound healing was assessed via ear hole closure. Parental strain MRL/MpJ can fully heal ear hole wounds within 30 days whereas parental strain CAST/Ei cannot. In general female animals are better healers than males (50% faster healing.) Genome scan was performed at an average resolution of 9.4 cM.

A suggestive QTL, Heal15, was identified on mouse Chromosome 2 mapping between 0-5cM peaking at marker D2Mit354. It was seen only in heterozygous mice at this locus.
