- a novel candidate breast cancer susceptibility locus on 6q14.1.

Most non- breast cancer families have no identified genetic cause. We used linkage and haplotype analyses in familial and sporadic breast cancer cases to identify a susceptibility locus on chromosome 6q. Two independent genome-wide linkage analysis studies suggested a 3 Mb locus on chromosome 6q and two unrelated Swedish families with a LOD >2 together seemed to share a haplotype in 6q14.

Whole-genome Linkage Analysis and Sequence Analysis of Candidate Loci in Familial Breast Cancer.

Background: Known breast cancer-predisposing genes account for fewer than 25% of all familial breast cancer cases and further studies are required to find the remaining high- and moderate-risk genes. We set-out to couple linkage analysis using microsatellite marker data and sequence analysis of linked regions in 13 non-BRCA1/2 families in order to find novel susceptibility loci and high-penetrant genes.

Materials And Methods: Genotyping with 540 fluorescently-labeled microsatellite markers located on the 23 chromosomes at 7.

Consensus based validation of membrane porins.

Porins are outermembrane beta-barrel proteins. They have varied biological functionality ranging from phage receptors, immunogenicity, pathogenicity to apoptosis. However, only a small number has been structurally and functionally characterised.
