In addition, since inappro­priate activation of Hh signalling can lead to the formation of medulloblastomas, rhabdomyosarcomas, basal carcinomas and other tumour types (Goetz & Anderson, 2010 ▶) and given the role of Kif7 in human primary cilia formation and Hh signalling (Karel et al., 2009 ▶), Kif7 might also be linked to other diseases such as cancer. The gene discussed is KIF7; the disease is rhabdomyosarcoma.
