Genetic Diseases

A relative has HCM? Cohort studies, the 2024 guideline and phase 3 trials explain gene testing, family heart checks, sports and new drugs.

Diverticulitis runs in families, yet most people with a family history or a high genetic score never get it. Here is what twin, gene and lifestyle studies show.

Is IBS genetic? Family, twin and GWAS studies show many small gene effects plus environment. What a 23andMe IBS score means, red flags, and treatments.

Is rosacea genetic? Twin and gene studies say genes matter, but triggers and care matter too. Real numbers, what a 23andMe report means, and US/Canada care.

Twin studies say acne is highly heritable, yet DNA scores predict it poorly. What the research means for parents, testing, treatment and privacy.

A 2025 gene study found 52 DNA regions tied to asthma risk. Here is what that and a new twice-yearly biologic drug mean for your family.

A 23andMe eczema risk score is not a diagnosis. See what the FLG gene, a 2023 gene study, and two new FDA-approved biologics actually mean.

A 23andMe lupus risk flag is not a diagnosis. See what the 2026 genetics study, GINA protections, and the newest FDA-approved treatment actually mean.

A 23andMe "higher likelihood" result for uterine fibroids is not a diagnosis. Here is what the genetics, the real risk, and your options actually mean.

A 23andMe "increased likelihood" glaucoma result is not a diagnosis. Here is what 263 risk loci, MYOC, and a real eye exam actually mean.
