Growth plays an essential role during development, as it provides the raw material upon which morphogenesis and cell differentiation can act. For an organism to achieve final shape and the right proportions between its body parts, such process has to be highly coordinated. However, to date, only very little is known about how growth and organ size are regulated. In this study, I used a forward genetic approach in the zebrafish Danio rerio to identify genes that can affect organ size and alter proportional growth. I analysed several N-ethyl-N-nitrosourea (ENU) induced adult viable mutants that develop enlarged fins. Through positional cloning I show that two of these, another longfin (alf) and pfau, bear a missense mutation in kcnk5b, a gene...
