title: Gene for hereditary motor and sensory neuropathy (proximal dominant form) mapped to 3q13.1.
abstract: Hereditary motor and sensory neuropathy with proximal dominant involvement (HMSN-P) has been reported as a new type of HMSN with the disease gene locus in the 3p14.1-q13 region. To further narrow down the gene locus, we performed fine linkage mapping using the linkage disequilibrium method. Analysis of DNA marker haplotypes and genetic cross-over sites showed the disease gene locus to be in the 3.1 cM interval bracketed by D3S1591 and D3S1281. Linkage disequilibrium analysis with DISMULT using 9 marker loci jointly in this region showed a lod score of 4.93 (P < 0.00000095). Consequently, the HMSN-P gene almost certainly lies on chromosome 3q13.1 and shows evidence of linkage disequilibrium.
