The human type II collagen gene (COL2A1) was mapped to chromosome 12 immediately proximal to fra(12)(q13.1) by the technique of nonisotopic (biotinylated) in situ hybridization. Thus, the COL2A1 gene was confirmed to be at the subband 12q13.11----q13.12, in agreement with previous reports. These results are not in agreement with the localization (12q14.3) cited in Ropers and Craig (1989).
通过非同位素(生物素化)原位杂交技术,将人类Ⅱ型胶原基因(COL2A1)定位到12号染色体上,紧邻fra(12)(q13.1)。因此,COL2A1基因被证实位于12q13.11----q13.12亚带,与先前的报道一致。这些结果与Ropers和Craig(1989年)引用的定位(12q14.3)不一致。
