An inherited EGFR T790M mutation is associated with roughly a 25-fold higher risk of lung cancer, with the association rising to about 62-fold among people who have never smoked.
Researchers studying autism-risk mutations found two opposing molecular patterns of brain gene activity across genetically different mouse models, and similar opposing patterns were also observed in human autistic-brain data.
Alzheimer’s disease can be transmitted from one person to another through ordinary close contact because amyloid-beta proteins can spread between people.
Claim 1 - TRUE ✅
Your claim is supported by the 2026 Science study. Researchers found that inherited EGFR T790M was associated with about a 25-fold increased lung-cancer risk, and the association was more than 60-fold among never-smokers.

Claim 2 - TRUE ✅
The study analyzed more than 1,000 brain transcriptomes across 17 genetically distinct autism mouse models and identified two opposing molecular patterns. Similar opposing molecular patterns were also observed in human autism-brain data. The researchers specifically cautioned that these findings do not establish two clinical types of autism.

Claim 3 - FALSE ❌
There is no evidence that Alzheimer’s disease spreads through ordinary close contact. The claim is plausible because researchers have documented unusual iatrogenic cases involving historical cadaver-derived human growth hormone contaminated with amyloid-beta. However, that is fundamentally different from ordinary person-to-person contact. A 2024 review concluded that there is no evidence Alzheimer’s disease is transmissible.
