    - Characterized dock8, the gene responsible for autosomal recessive Hyper IgE syndrome, in zebrafish and created a knockout model using morpholino antisense technology. We found ubiquitous expression in early development. Knockout of dock8 resulted in normal rag1 expression, but a dysmorphic phenotype and decreased phox2b expression, revealing a possible role for dock8 in brain development.- Funding: Human and Molecular Development Training Grant T32 HD07512 (2010-2012)
