Fourteen families with choroideremia (TCD) have been examined for linkage to nine genetic markers located on the proximal long arm of the X chromosome. Linkage to three markers (DXYS1, DXS72, DXS3) located in Xq21 was found with a four point lod score of 8.25. No evidence of submicroscopic deletions was observed using DXS233 and DXS232, both thought to lie within about 1 Mb of the TCD gene.
对14个患有先天性无脉络膜症(TCD)的家族进行了检测,以确定与位于X染色体长臂近端的9个遗传标记的连锁关系。发现与位于Xq21的3个标记(DXYS1、DXS72、DXS3)存在连锁关系,四点连锁值为8.25。使用DXS233和DXS232未观察到亚显微缺失的证据,这两个标记都被认为位于TCD基因约1 Mb范围内。
