1 http://genome.cse.ucsc.edu, no major deletions have been identified except for one report of an exon 60-62 genomic deletion [ 7 ] . Some correlations between FBN1 mutation genotypes and phenotypes are emerging.
We report here two multi-exon deletion mutations of FBN1 . We located the deletion breakpoints in introns and characterized the mutant RNA and protein phenotypes.
For example, exon-skipping mutations in the central region of the gene, exons 24-32, cause severe phenotypes or neonatal presentations [ 8 ] . But there are exceptions, only four of the many other mutations in this region cause severe phenotypes, while one mutation predicted to lead to skipping of exon 24 was found in a patient with classic MFS [ 5 ] . In contrast, most cysteine substitutions cause classic MFS with a high frequency of lens dislocation, although some patients in our study did not meet the Ghent criteria for diagnosis of MFS [ 9 ] . Amino-acid substitutions not disrupting disulfide bonds may be associated with fibrillinopathies other than MFS, although mutations in the calcium-binding consensus sequence have been reported in individuals with classic MFS [ 5 10 11 12 ] . It is clear from the studies reported so far, that genotype-phenotype correlations are not straight-forward for FBN1 mutations.
Thus, we have only detected two genomic deletions out of 105 unique disease-causing FBN1 mutations identified in our laboratory.
The MFS phenotype is the result of mutations in FBN1, a large gene composed of 65 exons encoding the 350 kD fibrillin-1 protein that is the major constituent of microfibrils in the extracellular matrix (reviewed in [ 3 ] ). To date, 201 unique FBN1 mutations have been identified, including 70 (34.
