Sluc30^O20/A
QTL Variant Detail

Summary

• QTL variant: Sluc30^O20/A
• Name: susceptibility to lung cancer 30; O20/A
• MGI ID: MGI:3033810
• QTL: Sluc30 Location: Chr7:19431696-19431844 bp Genetic Position: Chr7, cM position of peak correlated region/allele: 9.94 cM
• QTL Note: genome coordinates based on the marker associated with the peak LOD score

Variant origin

• Strain of Specimen: O20/A

Variant description

• Allele Type: QTL

Notes

Sluc23 and Sluc30 interact. Heterozygosity at Sluc23 and homozygosity for O20/A-derived alleles at Sluc30 confers increased lung tumor size.

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

J:71973

Several F2 crosses between inbred strain O20/A and recombinant congenic strains OcB-3/Dem, OcB-4/Dem, OcB-6/Dem, OcB-9/Dem, and OcB-16/Dem were used to map QTLs linked to lung tumor susceptibility. Parental strain O20/A and OcB-4/Dem are susceptible to lung tumor development after ENU treatment whereas parental strains OcB-3/Dem, OcB-6/Dem, OcB-9/Dem, and OcB-16/Dem are relatively resistant. 14 previously identified lung tumor susceptibility loci were detected in these crosses (Sluc1-Sluc14) and 16 new loci were identified with a statistical significance of P>0.05. All of the QTL were detected in pairwise interactions, Table 1, Fig 1.

In the (OcB16 x O20/A)F2 cross newly identified QTL Sluc19 mapped to Chr 7 in linkage with D7Mit105 at approximately 63.5 cM.

In the (OcB3 x O20/A)F2 cross newly identified Sluc30 mapped to mouse Chr 7 in linkage with D7Mit57 at approximately 4 cM.
