Your genetic profile decides severity of asthma symptoms
Turns out, asthma patients with a specific genetic profile exhibit more intense symptoms of asthma following exposure to vehicular pollution. According to researchers at the National Institutes of Health, asthma patients who lack this specific genetic profile do not have the same sensitivity to vehicular pollution and do not experience worse asthma symptoms. The scientists stated that the results were based on genetic variation, the subtle differences in DNA that make each person unique. They further added that to understand the concept, one should think of human genes, which are made up of DNA base pairs A, C, G, and T, as written instructions for making proteins. "All humans have the same genes, in other words, the same basic instructions, but in some people, one DNA base pair has been changed. This common type of genetic variation is called a single nucleotide polymorphism or SNP, and it can alter the way proteins are made and make individuals more or less prone
