Abstract

Background: The ever on-going technical developments in Next Generation Sequencing have led to an increase in detected disease related mutations. Many bioinformatics approaches exist to analyse these variants, and of those the methods that use 3D structure information generally outperform those that do not use this information. 3D structure information today is available for about twenty percent of the human exome, and homology modelling can double that fraction. This percentage is rapidly increasing so that we can expect to analyse the majority of all human exome variants in the near future using protein structure information.

Results: We collected a test dataset of well-described mutations in proteins for which 3D-structure information is available. This test dataset was used to analyse the possibilities and the limitations of methods based on sequence information alone, hybrid methods, machine learning based methods, and structure based methods.

Conclusions: Our analysis shows that the use of structural features improves the classification of mutations. This study suggests strategies for future analyses of disease causing mutations, and it suggests which bioinformatics approaches should be developed to make progress in this field.

Performance of the mutation analysis servers grouped by type. Shown is the average percentage of the correctly predicted pathogenic mutants and neutral SNPs. The different servers are divided in groups based on their underlying methods. G = Grantham scores only, MSA = Multiple Sequence Alignment-centred methods (PhD-SNP, Panther, and SIFT), ML = Machine Learning based methods (SNPs&GO, SNAP, MutPred), 3D = structure based methods (nsSNPanalyzer, SNP3D, PolyPhen-2, and HOPE).

Figure 2
Mutation W177R in opsin. The opsin molecule is shown in grey, the side chain of wildtype tryptophan and mutant arginine are shown in green and red, respectively. The picture illustrates that the tryptophan residue is located at the surface where it can make hydrophobic interactions with the membrane.

Figure 3
Mutation V359 in SPTC2. The SPTC2 molecule is shown in grey, the side chain of wildtype valine and mutant methionine are shown in green and red respectively. Other side chains of surrounding residues are also shown in grey and indicate that the residue is buried.
