Sonic hedgehog is the name of a gene - it was named over a decade ago. It was called that because it was a new member of the 'hedgehog' family of genes. The only other gene name that has been changed after corporate intervention was a gene in the fruitfly that was called 'velcro' and was renamed 'puckered'. Fruitflies have a large number of whimsically named genes - my favourite (also a possible trademark violation) being 'Ken and Barbie' since flies lacking the gene have no external genitalia.
