IS ASTHMA GENTIC? CAUSES AND RISK FACTORS
Genetics can affect
Genetics can affect the likelihood of a person having asthma.
All types of asthma can have a genetic component. Some different types of asthma include:
- adult-onset asthma
- exercise-induced bronchospasm
- allergic asthma
- nonallergic asthma
- occupational asthma
- asthma with chronic obstructive pulmonary disease
A person is more likely to develop asthma if they have a family history of the condition. This means that asthma can be genetic. Some researchers describe it as a “highly heritable disease.”
According to a 2014 review study, genetic factors account for around 70 percent of a person’s risk of developing asthma, meaning that genes play a large role in whether or not a person develops the condition.
However, genetics are not the only cause of asthma. Some people develop it when they have no family history of the condition. Likewise, a person may have a genetic tendency toward asthma but never actually develop it.
Genetics play less of a role in asthma development later in life, so adult-onset asthma and occupational asthma are slightly less dependent on genes.
A person can also develop asthma without any genetic predisposition for the condition. In fact, many environmental factors can cause a person to develop it.
