| Remarks |
Clinically affected; aortic dilatation; dolichostenomelia; arachnodactyly; scoliosis; joint laxity; high narrow palate; pectus deformity; ectopia lentis; myopia; donor subject has an intronic mutation in the FBN1 gene: IVS46+5G>A (5788+5G>A) leading to in-frame skipping of the preceding exon. |
