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

J:93171

Two different intercrosses totaling 1045 (LG/J x SM/J)F2 intercross animals were used for linkage analysis to identify QTLs for mandible length. A total of 96 microsatellite markers at an average spacing of 23 cM were used in the genome scan. The QTLs identified for mandible length were evaluated for relationship to other mandible traits. 13 QTLs reaching the chromosome- and genome-wide significance threshold of 0.05 were identified.

Manln1 (mandible length 1) mapped to 48 cM on mouse Chromosome 1 near D1Mit7 (LOD=8.66). The QTL interval of Manln1 spans 36 cM - 52 cM. LG/J-derived alleles confer increased mandible length at Manln1 with a dominant mode of inheritance. This locus explains 4% of the variance.

Manln2 mapped to 52 cM on mouse Chromosome 2 near D2Mit370 (LOD=4.64). The QTL interval of Manln2 spans 42 cM - 60 cM. This locus is linked to many different mandible traits affecting the muscle attachment area.

Manln3 mapped to 34 cM on mouse Chromosome 3 in linkage to D3Mit22 (LOD=2.75). The QTL interval of Manln3 spans 14 cM - 56 cM. LG/J-derived alleles confer increased mandible length at Manln3 with a dominant mode of inheritance. This locus explains 1.3% of the variance. Manln3 also shows linkage to several different mandible traits affectingthe alveolar processes (LOD=7.75 at D3Mit22).

Manln4 mapped to 16 cM on mouse Chromosome 4 near D4Mit163 (LOD=3.46). The QTL interval of Manln4 spans 8 cM - 20 cM.
