Misleading linkage results in an NF2 presymptomatic test owing to mosaicism.

abstract：BACKGROUND:We have previously described an autosomal recessive syndrome of macrocephaly, multiple epiphyseal dysplasia (MED), and distinctive facies in a large, extended Omani family. The MED observed seems to be part of a larger malformation syndrome, since both craniofacial and central nervous system changes were pre...
