Gene identification - Marfan syndrome

  • MFS suggested as linked to Rh

    MFS suggested as linked to Rh
  • MFS linked to abnormal COL1A2

    MFS linked to abnormal COL1A2
  • a2(I) and a1(III) collagen genes ecluded as mutant loci for MFS

  • More evidence accumulates excluding colagen associated genes

  • Exclusion map suggested

  • Connective tissue gene research dimonates, with a gene exclusion map building

  • Chromosome 15 suggested as location of MFS mutant

  • Chromosome 15 confirmed, tightly linked markers identified at 15q15-q21.3

  • Linkage studies conclude MFS locus to be located between markers D15S48 and D15S49

  • Demonstration of first MFS patient with fibrillin mutation - fibrillin locus on chromosome 15 elected as syndrome causing locus

  • Evidence electing fibrillin as the syndrome causing gene continues to build

  • Fibrillin gene mapped to chromosome 15 band q21.1

  • International study results agree with previous conclusions
