In addition, the clinical sensitivity of tests for
common risk alleles is not necessarily high.
Common risk alleles with a known association with a condition can inform an individual of an increased or decreased risk of developing the condition in question; however, the degree of certainty is often unknown.
Use of
common risk alleles for changes in clinical management can be challenging without a professional guideline.
Common risk alleles are often detected by genome - wide association studies (GWAS) 1,2.
The MAF of
common risk alleles can range from 5 % to 50 %.
These limitations can make the interpretation of
common risk alleles challenging.
The presence of
a common risk allele can indicate a need for increased surveillance, while a negative result implies a risk similar to the general population.
The impact of
a common risk allele with disease risk is often modest, as is its impact on clinical care.
Not exact matches
No
common BRCA mutations, no APOE
risk alleles.
Performing genetic studies in multiple human populations can identify disease
risk alleles that are
common in one population but rare in others, with the potential to illuminate pathophysiology, health disparities, and the population genetic origins of disease
alleles.
In contrast, more than 70 other
common alleles have been associated with breast cancer susceptibility, most of which confer only a mild to moderate increase in
risk.
However, caution should be used in aggressively selecting against mutant
alleles which have low penetrance or low
risk for the disease state when the mutant
alleles are
common throughout the breed.
The associated
alleles were
common in the studied populations and all had only small effects on disease
risk [123].
