Giving in to the blues

Abstract

The molecular players that direct the development of mammalian photoreceptors are slowly coming into focus. A study that elucidates the cause of enhanced S-cone syndrome, a disorder that may be caused by a distortion of retinal cell fate, reveals one such factor—although questions about its effects remain.
