Recently published NF papers cover a range of topics. These include: the controversial issue of using radiotherapy to treat NF2 tumors; how a patient’s NF2 genetic status might predict severity of the condition; molecular advances in understanding the function of NF2 protein merlin (by recent CTF Young Investigator Awardee Timmy Mani); a role for the Spred-1 (Legius Syndrome) gene in controlling brain development and patterning; new zebrafish models of NF1 that have vascular and cardiac valve abnormalities; speech charasteristics seen in NF1 patients; and the first case of germ line mosaicism in schwannomatosis.
