incomplete penetrance

Because of incomplete penetrance leading to a variety of clinical phenotype and passive carriers that are not clinical symptoms , Singh and other advocates want to use complex multi-genetic inheritance to explain the phenotypic heterogeneity of GEFS + features .

由于有不完全外显率导致临床的各种表型及一些没有临床症状的被动携带者，Singh等主张以复杂性多基因遗传来解释GEFS+表型异质性的特性。

There is no intrinsic causal fixed relationship between genotype and phenotype due to incomplete penetrance .

由于表型的不全外显，基因型和表型之间无固定内在因果模式。

We examined three families and suggest that it has an autosomal dominant trait with incomplete penetrance .

我们研究了三个家庭，并表明，它有一种常染色体显性不完全外显。

The asymptomatic parents were found from one symptomatic member V1 , which suggested incomplete penetrance of the mutation .

而患者（V1）双亲都无症状，提示该突变基因存在外显不全。
