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.
