What does having a genetic risk or predisposition consist of?
It consists of having an increased probability of developing a disease or presenting a complex personal trait. This probability can be increased or decreased based on the presence or absence of certain genetic variants in the DNA sequence.
It should be noted that having a high risk or genetic predisposition to diseases or traits does not necessarily mean that one will suffer from it, but that from a genetic point of view, known as genetic factor, this tendency is present.
However, genetic predisposition does not take into account environmental factors, as they are external to the organism itself and independent of its DNA. Moreover, it may happen that there are unknown genes involved in these pathologies and traits that are not being considered in the analyses.
