Software and database for the analysis of mutations in the human FBN1 gene
1INSERM U383, Hôpital Necker-Enfants Malades, Université René Descartes, Paris, France.
Abstract:
Fibrillin is the major component of extracellular microfibrils. Mutations in the fibrillin gene on chromosome 15 (FBN1) were described at first in the heritable connective tissue disorder, Marfan syndrome (MFS). More recently, FBN1 has also been shown to harbor mutations related to a spectrum of conditions phenotypically related to MFS and many mutations will have to be accumulated before genotype/phenotype relationships emerge. To facilitate mutational analysis of the FBN1 gene, a software package along with a computerized database (currently listing 63 entries) have been created.
Insights
Fibrillin-1 (FBN1) gene mutations cause Marfan syndrome and related disorders. A new software and database aid in analyzing these FBN1 mutations for better genotype/phenotype understanding.
Area of Science:
- Genetics
- Molecular Biology
- Connective Tissue Disorders
Background:
- Fibrillin is a key protein in extracellular microfibrils.
- Mutations in the FBN1 gene are linked to Marfan syndrome (MFS).
- FBN1 mutations are also associated with a broader range of MFS-related conditions.
Purpose of the Study:
- To facilitate the mutational analysis of the FBN1 gene.
- To aid in understanding genotype/phenotype relationships in FBN1-related disorders.
Main Methods:
- Development of a specialized software package.
- Creation of a computerized database for FBN1 mutations.
Main Results:
- A software package and database have been created.
- The database currently contains 63 entries of FBN1 mutations.
Conclusions:
- The developed tools will assist in the ongoing mutational analysis of FBN1.
- Accumulating mutation data is crucial for elucidating genotype/phenotype correlations.
