Genes products in bold are also essential developmental genes in fish embryos according to Amsterdam et al. (2004). Note that relative gene expression (log₂ values) is expressed relative to the normal group. When several transcripts match to the same gene product, relative gene expression was calculated as the mean of all transcripts matching to that gene product.
