J. Hazan et al., LINKAGE OF A NEW LOCUS FOR AUTOSOMAL-DOMINANT FAMILIAL SPASTIC PARAPLEGIA TO CHROMOSOME 2P, Human molecular genetics, 3(9), 1994, pp. 1569-1573
Autosomal dominant familial spastic paraplegia (AD-FSP) is a genetical
ly heterogeneous neurodegenerative disorder characterized by a spastic
ity of the lower limbs. A locus causing AD-FSP (FSP1) has been previou
sly mapped to chromosome 14q. We now report linkage of a second AD-FSP
locus (FSP2) to chromosome 2p21-p24 in five of seven French families
and one large Dutch pedigree. The analysis of recombination events and
multipoint linkage place FSP2 within a 4 cM interval flanked by loci
D2S400 and D2S367.
