Positional cloning with microsatellite markers allowed further localization of the Darier disease gene to a 2-cM interval of chromosome 12, 12q23-24.1, between the polymorphic loci D12S234 and D12S129. A region this size is suitable for construction of a contig to identify the Darier disease gene. Use of a polymorphic intronic marker for nitric oxide synthetase 1 gene, which maps to the same chromosomal area as the Darier gene, allowed exclusion of that gene as the Darier disease gene.
利用微卫星标记进行的定位克隆将 Darier 病基因进一步定位于 12 号染色体 12q23 - 24.1 的一个 2 厘摩区间,该区间位于多态性位点 D12S234 和 D12S129 之间。这样大小的区域适合构建重叠群以鉴定 Darier 病基因。使用与一氧化氮合酶 1 基因相关的多态性内含子标记(该标记定位于与 Darier 基因相同的染色体区域),得以排除该基因作为 Darier 病基因。
