Our group has been working on the genetics of lupus for over 15 years. We have identified several genes for lupus, such as PDCD1 and BANK1, and we have also contributed to the better understanding of the mechanisms in which the gene variants affect gene function, a field in which we have gained experience.
The last few years have witnessed an explosion of data where genes for several common diseases have been identified. This data can now be exploited fully to understand the mechanisms in which the genes function or interact to lead to a disease.
The aim of our research is precisely to understand those interactions and translate them into biologically relevant information that we can test experimentally.
We are also focusing on less-studied populations, in particular Hispanics. Hispanics with lupus have a very severe disease and usually develop kidney inflammation, one of the major complications of lupus. We aim to understand if the mixture of European and Native American and/or Amerindian genetic variation may predispose these individuals to a higher risk of developing a more severe clinical picture.

The identification of genes for lupus will lead to a better understanding of disease pathogenesis. My group has been working for several years in the identification of new genes for lupus. Within the various genes for lupus known to date, we identified PDCD1 and BANK1. These studies include the understanding of the functional basis of the variants or mutations underlying lupus susceptibility. Thus, we study in detail the new susceptibility genes to determine if functional variation in each gene affects gene expression or splicing or might have other consequences on gene function.
However most genetic risks identified to date have very small individual effects on the lupus phenotype. Whether gene-gene interactions might underlie major effects on the risk to develop lupus is one of the goals of our research. Further, we take a step forward and ask ourselves if the genetic interactions reflect true biological processes, and we investigate if the interacting genes code for proteins that may bind to each other or interact functionally in the same biological process.
A second goal in our studies is to identify susceptibility genes of Amerindian origin (Native American or Native Latin American) in individuals of Hispanic ancestry. Hispanics develop at times a severe lupus with many clinical complications and understanding how ancestry and admixture contributes to development of the disease is part of our studies.
For our studies, we count with numerous national and international collaborations that have provided us with an extensive resource of samples.
