    ABSTRACT: Although snoring is common in the general population, its aetiology has been largely understudied. Here we report a genetic study on snoring (n ~ 408,000; snorers ~ 152,000) using data from the UK Biobank. We identify 42 genome-wide significant loci, with an SNP-based heritability estimate of ~10% on the liability scale. Genetic correlations with body mass index, alcohol intake, smoking, schizophrenia, anorexia nervosa and neuroticism are observed. Gene-based associations identify 173 genes, including DLEU7, MSRB3 and POC5, highlighting genes expressed in the brain, cerebellum, lungs, blood and oesophagus. We use polygenic scores (PGS) to predict recent snoring and probable obstructive sleep apnoea (OSA) in an independent Australian sample (n ~ 8000). Mendelian random

Lifestyle context

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

Lifestyle

  • Body mass index and weight management Moderate

    Mendelian randomization analysis indicates a causal relationship between elevated BMI and snoring risk

    Maintain BMI below 25; discuss weight loss strategies with clinician if elevated

  • Excessive alcohol consumption Moderate

    Alcohol consumption frequency is associated with snoring prevalence, potentially through pharyngeal muscle relaxation

    Limit alcohol to moderate intake per health guidelines

  • Tobacco smoking Moderate

    Smoking frequency is significantly associated with snoring prevalence, potentially through airway inflammation and irritation

    Avoid smoking; seek cessation support if currently smoking

Screening

  • Sleep apnea evaluation if snoring symptoms present Moderate

    Snoring is a hallmark of obstructive sleep apnea; this genetic variant increases snoring risk, warranting OSA screening if symptoms develop

    Discuss snoring or witnessed breathing pauses with clinician; request sleep study if indicated
