A genetic map of highly polymorphic microsatellite markers spanning the von Hippel-Lindau region (VHL) of 3p25 was constructed using the CEPH reference pedigrees. A greater than 1000:1 odds map of pter-D3S1038-RAF1-D3S651-D3S656-D3S110- D3S1255-cen was found. Genotyping of six multigenerational VHL families showed the region surrounding the D3S1038 marker to be the most likely location for the VHL gene with a peak location score of 10.04 with VHL completely linked to D3S1038. These data provide an initial high resolution genetic map of this region; D3S1038 appears to be a highly polymorphic marker that should prove useful in the future for presymptomatic diagnosis.
利用CEPH参考家系构建了跨越3p25的冯·希佩尔-林道区域(VHL)的高度多态性微卫星标记的遗传图谱。发现了一个从染色体短臂末端到D3S1038-RAF1-D3S651-D3S656-D3S110-D3S1255-着丝粒的大于1000:1的优势图谱。对六个多代VHL家系进行基因分型显示,D3S1038标记周围区域最有可能是VHL基因的位置,VHL与D3S1038完全连锁时的峰值定位分数为10.04。这些数据提供了该区域的初始高分辨率遗传图谱;D3S1038似乎是一个高度多态性的标记,未来应会被证明对症状前诊断有用。
