Research Description
The focus of my laboratory is to develop and perform comprehensive mutation analysis and interpretation for complex or challenging genetic disorders using multiple approaches. The primary focus of my clinical work is the development of high-throughput sequencing strategies for rare disorders using sequence capture technologies, robotics, next generation sequencing, oligonucleotide array platforms, robotics and using predictive analysis tools and biological testing. My research is focused on functional analysis of sequence variants in disease associated genes specifically mental retardation and muscular dystrophies and translating what is learned in the basic research laboratory to clinical practice. The ultimate goal is to create an algorithm that will be clinically useful for interpretation of novel sequence variants. We are also interested in identifying novel genes in these diseases using next generation tools and a laboratory developed bridged approach to whole exome sequencing. An understanding of the important changes will eventually provide an opportunity to improve the early detection of disease, and to target more effective treatment.
