Abstract

Hereditary spastic paraplegia is a genetically and phenotypically heterogeneous disorder. Both pure and complicated forms have been described, with autosomal dominant, autosomal recessive, and X-linked inheritance. Various loci (SPG1-SPG6) associated with this disorder have been mapped. Here, we report linkage analysis of a large consanguineous family affected with autosomal recessive spastic paraplegia with age at onset of 25-42 years. Linkage analysis of this family excluded all previously described spastic paraplegia loci. A genomewide linkage analysis showed evidence of linkage to chromosome 16q24.3, with markers D16S413 (maximum LOD score 3.37 at recombination fraction [theta] of .00) and D16S303 (maximum LOD score 3.74 at straight theta=.00). Multipoint analysis localized the disease gene in the most telomeric region, with a LOD score of 4.2. These data indicate the presence of a new locus linked to pure recessive spastic paraplegia, on chromosome 16q24.3, within a candidate region of 6 cM.

摘要

遗传性痉挛性截瘫是一种遗传和表型均异质性的疾病。已描述了单纯型和复杂型，其遗传方式包括常染色体显性遗传、常染色体隐性遗传和X连锁遗传。与该疾病相关的多个位点（SPG1-SPG6）已被定位。在此，我们报告了一个患常染色体隐性痉挛性截瘫的大家族的连锁分析，其发病年龄在25至42岁之间。对该家族的连锁分析排除了所有先前描述的痉挛性截瘫位点。全基因组连锁分析显示与16号染色体q24.3存在连锁证据，标记为D16S413（在重组率[θ]为0.00时最大对数优势分数为3.37）和D16S303（在直接θ = 0.00时最大对数优势分数为3.74）。多点分析将疾病基因定位在最末端区域，对数优势分数为4.2。这些数据表明在16号染色体q24.3上一个6厘摩的候选区域内存在一个与单纯隐性痉挛性截瘫相关的新位点。
