Corroboration of a familial chordoma locus on chromosome 7q and evidence of genetic heterogeneity using single nucleotide polymorphisms (SNPs).

Abstract excerpt

Chordoma, a rare bone tumor originating from notochordal remnants, has a genetic predisposition in some families. Previously, we performed linkage analysis using microsatellite (STR) markers on 3 unrelated chordoma kindreds (16 patients with chordoma) and reported significant evidence for linkage to chromosome 7q33 (Z(max) = 4.78) with a minimal disease gene region of 11 cM. In our present study, we performed...
