NF2 and schwannomatosis: Linkage analysis with microsatellite markers performed in families affected with schwannomatosis served to exclude the NF2 gene as a germline-transmissible schwannomatosis predisposition gene but nevertheless suggested that such a gene could be located within an 8.48-Mb region centromeric to NF2, between markers D22S420 and D22S1148 in the vicinity of D22S1174 on chromosome 22 (MacCollin et al. 2003) (Fig. 2).
