... acti- vation of a cryptic splice site is a common cause of genetic disease. We recently reported the example of a deep intronic mutation c.31-279A>G in the NF1 gene of a patient with a severe form of ... exclusion. However, given that the m4 motif is immediately adjacent to the 5¢ splice site, it is very likely that this mutation is involved in recognition of this seque...
