Bpq6^C57BL/6J
QTL Variant Detail

Summary

• QTL variant: Bpq6^C57BL/6J
• Name: blood pressure QTL 6; C57BL/6J
• MGI ID: MGI:2389420
• QTL: Bpq6 Location: Chr15:45282646-45282739 bp Genetic Position: Chr15, cM position of peak correlated region/allele: 17.41 cM
• QTL Note: genome coordinates based on the marker associated with the peak LOD score

Variant origin

• Strain of Specimen: C57BL/6J

Variant description

• Allele Type: QTL
• Mutation: Undefined
• This allele confers increased blood pressure compared to A/J. (J:66987)
• Inheritance: Other (see notes)

Notes

Interaction occurs between Bpq5 and Bpq6. Homozygosity for C57BL/6J-derived alleles at Bpq6 and heterozygosity at Bpq5 results in increased blood pressure.

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

J:66987

C57BL/6J are sensitive to salt induced hypertension whereas A/J are non-salt-sensitive allowing for a genome wide scan for loci contributing to hypertension. 250 male mice from reciprocal backcrosses between (C57BL/6J x A/J)F1 x C57BL/6J were informativein mapping 6 Blood pressure QTLs to 5 mouse chromosomes. Beq6 interacted with Bpq5 and mapped with markers on mouse Chromosome 15. Bpq6 mapped with D15Mit152 with an F value of 19.8 and a P value of 0.0020. Suggested candidates for Bpq6 were Ptgerep2 andNpr3.
