  • Genetic Architectures of Childhood- and Adult-Onset Asthma Are Partly Distinct. - American journal of human genetics (2020) · Ferreira MAR, Mathur R, Vonk JM, Szwajda A, Brumpton B, Granell R, Brew BK, Ullemar V, Lu Y, Jiang Y, Magnusson PKE, Karlsson R, Hinds DA, Paternoster L, Koppelman GH, Almqvist C · PubMed 30929738

    The extent to which genetic risk factors are shared between childhood-onset (COA) and adult-onset (AOA) asthma has not been estimated. On the basis of data from the UK Biobank study (n = 447,628), we found that the variance in disease liability explained by common variants is higher for COA (onset at ages between 0 and 19 years; h = 25.6%) than for AOA (onset at ages between 20 and 60 years; h = 10.6%). The genetic correlation (r ) between COA and AOA was 0.67. Variation in age of onset among COA-affected individuals had a low heritability (h = 5%), which we confirmed in independent studies and also among AOA-affected individuals. To identify subtype-specific genetic associations, we performed a genome-wide association study (GWAS) in the UK Biobank for COA (13,962 affected individuals) a

Lifestyle context

Concrete actions anchored to the cited research. We do not prescribe, we describe.

Discuss with your doctor

  • asthma risk assessment and preventive strategies Moderate

    Strong genetic association warrants clinical evaluation for prevention and early treatment

    Schedule discussion with physician about asthma risk and possible preventive approaches

Lifestyle

  • prolonged air pollution and respiratory irritant exposure Moderate

    HLA-DRB1 variant increases airway sensitivity to environmental asthma triggers

    Limit time in polluted environments; use air filters when needed

Screening

  • asthma screening and spirometry testing Moderate

    Risk allele at HLA-DRB1 associated with 20.5% increased asthma risk across 341,215 individuals

    Consult physician for asthma assessment if not previously evaluated
