项目摘要
ABSTRACT
Next generation genome scale sequencing of patients is now becoming routine for two classes of disease: rare
Mendelian traits and cancer. In favorable cases, these data allow identification of relevant mutations and thus
aid diagnosis and therapy. In both classes of disease, the most common type of mutation is missense - single
base changes that result in an amino acid substitution in a protein. Uncertainty as to the impact of these
mutations on in vivo protein activity has resulted in a very conservative approach to their interpretation in the
clinic, so causing many missed opportunities for targeted treatment. The goal of this project is to use a
combination of three strategies to make the interpretation of these mutations much more applicable in the clinic.
There are already a large number of computational methods that attempt to determine the impact of missense
mutations on function, and there is substantial evidence that these have useful accuracy. The primary difficulty
is that the accuracy in any particular case is not reliably calibrated. Therefore, our first aim is to use a combination
of these methods to develop an approach focused on more reliable estimates for the probability of high impact
on protein function (i.e. more confident P values). The second aim is to maximize the utilization of three-
dimensional structural information, largely ignored by most computational methods. A large fraction of missense
mutations in these classes of disease act by destabilizing protein structure and knowledge of structure allows
these to be identified with much higher reliability. Also, structure provides a framework for detailed annotation
and comprehension of function. To facilitate the utilization of structure, we will implement a modeling platform
that leverages available experimental information to maximize the structural data available for analyzing mutation
impact. An important aspect of the platform is incorporation of methods for evaluating the reliability of the
structural features relevant to analysis of each mutation. In the third aim we will build specific functional models
for each protein of interest, integrating information from current databases, the literature, and community input,
so as to provide the richest possible background against which to judge the impact of mutations. Proteopedia, a
well established media wiki for proteins, will be used to provide an integrated view of text, data, and structure. A
key component of the information resource will be contributions from curators, who will provide annotation and
also solicit input from other experts. This aspect of the project builds on experience with other crowdsourcing
endeavors, including CASP, CAGI and Proteopedia. There will be three primary outcomes from the project:
First, improved reliability for the interpretation of missense mutations. Second, a prototype mutation annotation
procedure suitable for use in a clinical setting. Third, the resource will provide information of benefit to a range
of other scientists, thus facilitating the analysis of disease related mutations.
