GIRIRAJAN LAB
Our research
The Girirajan laboratory is interested in untangling the genetic and phenotypic heterogeneity associated with neurodevelopmental disorders including autism spectrum disorders, schizophrenia, epilepsy, and intellectual disability disorders. There is extensive genetic heterogeneity (i.e. more than one gene or genomic region implicated) for neurodevelopmental disorders such as, for example, autism and developmental delay suggesting a larger genetic target. And, even among individuals carrying the same genetic variant, significant phenotypic heterogeneity (difference in the clinical presentation) has been documented. This has posed considerable challenges in understanding the role of discovered genetic variants in terms of disease causation, diagnosis, and interpretation for management and treatment. The function of these variants in the etiology and pathogenesis of neurodevelopmental disorders is unknown. Our research incorporates high-throughput genomic techniques including array comparative genomic hybridization, genome and transcriptome sequencing, computational approaches, and model organisms to understand the genetic basis of human complex disease.
