Apmt1^FVB/NJ
QTL Variant Detail

Summary

• QTL variant: Apmt1^FVB/NJ
• Name: accelerator of polyoma-induced mammary tumors 1; FVB/NJ
• MGI ID: MGI:2157320
• QTL: Apmt1 Location: unknown Genetic Position: Chr15, cM position of peak correlated region/allele: 22.82 cM
• QTL Note: genome coordinates based on the marker associated with the peak LOD score

Variant origin

• Strain of Specimen: FVB/NJ

Variant description

• Allele Type: QTL
• Mutation: Undefined
• This allele confers increased mammary tumor susceptibility compared to I/LnJ. (J:64663)
• Inheritance: Other (see notes)

Expression

In Structures Affected by this Mutation:

1 anatomical structure(s)

Notes

Apmt1 exhibits additive inheritance and interacts epistatically with Apmt2. Animals homozygous for FVB/NJ-derived alleles at Apmt1 and heterozygous at Apmt2 exhibit the highest incidence of mammary tumors.

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

J:64663

A genome wide scan using 69 markers was initiated to find loci responsible for tumor acceleration in mice. A total of 126 female mice from FVB/N females X (I/LnJ females X FVB/N-TgN(MMTVPyVT)^634mul males) F1 males were informative. A region of mouse Chromosome 15 was associated with an acceleration of tumorignensis in I/LnJ mice with a peak LOD score (3.3) near D15Mit184.
