  1. Penetrance

    Penetrance in genetics is the proportion of individuals carrying a particular variant of a gene that also express an associated trait. In medical genetics, the penetrance of a disease-causing mutation is the proportion of individuals with the mutation who exhibit clinical symptoms. For example, if a mutation in the gene responsible for a particular autosomal dominant disorder has 95% penetrance, then 95% of those with the mutation will develop the disease, while 5% will not. Common examples used to show degrees of penetrance are often highly penetrant. There are several reasons for this: ⁕Highly penetrant alleles, and highly heritable symptoms, are easier to demonstrate, because if the allele is present, the phenotype is generally expressed. Mendelian genetic concepts such as recessiveness, dominance, and co-dominance are fairly simple additions to this principle. ⁕Alleles which are highly penetrant are more likely to be noticed by clinicians and geneticists, and alleles for symptoms which are highly heritable are more likely to be inferred to exist, and then are more easily tracked down.

U.S. National Library of Medicine

  1. Penetrance

    The percent frequency with which a dominant or homozygous recessive gene or gene combination manifests itself in the phenotype of the carriers. (From Glossary of Genetics, 5th ed)
