Research Synopsis

 
Research in the Wevrick laboratory focuses on genetic disorders that affect human development. We have specific interests in pediatric obesity, developmental delay, and also study developmental aspects of gene regulation. We identified genes that are inactivated in Prader-Willi syndrome, a sporadic chromosomal disorder that causes neonatal hypotonia, developmental delay, compulsive overeating leading to obesity, and abnormalities of sleep and respiration. We are currently studying the roles of these genes in the normal development of the nervous, muscular, and endocrine systems. Two genes, necdin and MAGEL2, have specific roles in growth and differentiation. We are using mouse models to evaluate the normal roles of these proteins and the effect of their loss in Prader-Willi syndrome. This work is funded by CIHR, NSERC, and the Foundation for Prader-Willi Research.

Rachel Wevrick co-discovered many of the genes inactivated in Prader-Willi syndrome, including Necdin, MAGEL2, and IPW. Her research focuses on the genetic basis of developmental delay and obesity, using tools in molecular and cellular  biology and mouse models to investigate the gene and protein function, specializing in the development of the nervous, muscle, and endocrine systems.
