QTL: Leg1  Location: unknown  Genetic Position: Chr8, Syntenic
Strain of Specimen:  BALB/cBy
Allele Type:    QTL

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


Polymorphic markers were screened in two different complex crosses to identify QTLs associated with increased lifespan. Leg1, a QTL exhbiting significant linkage (P = 5.4 x 10-5) to longevity, was detected on mouse Chromosome 8 in a (LP/J x MOLD/Rk)F1 x (NZW/LacJ x BALB/cBy)F1 population. Leg1 spans approximately 7.5 cM - 12.5 cM on mouse Chromosome 8 and is associated with markers D8Mit290 and D8Mit171. MOLD/Rk-derived alleles confer increased longevity by 110 days at Leg1. On mouse Chromosome 10, a QTL associated with longevity (P = 2.6 x 10-5), Leg2, was identified in a (ST/bJ x C57BL/6J)F1 x (CAST/Ei x DBA/2J)F1 population. Leg2 spans approximately 65 cM - 70 cM on mouse Chromosome 10 and is associated with marker D10Mit267. CAST/Ei-derived alleles confer increased longevity by 110 days at Leg2.
