It is now known that genetic variability accounts for 25% of susceptibility to the disease, but that variations in the sickle-cell gene contribute to only a fraction of that.
现在，25 %的对疾病的敏感性被归咎于遗传变异。但在镰细胞基因上的变异仅仅参与了其中的一小部分。

This variability means that a small deletion on the CCR5 gene.
这种变异是指CCR5基因上一小段缺失。

Objective To assess the stability and variability of the LMP1 gene and protein in nude-mice transplanted tumor models of extranodal nasal type NK/T-cell lymphoma.
