I did promethease. For alzheimers/dementia It said
increased dementia risk Increased risk of frontotemporal dementia, alzheimer’s disease and parkinson’s disease.
Faster aging. Increased risk for Dementia. Less good cholesterol. This reduces HDL (‘good’) cholesterol. HDL cholesterol removes cholesterol from artery walls and improves health. This SNP seems to be associated with higher blood pressure, less longevity, and more diseases of aging, in particular memory decline and dementia, and lower odds of living to 100, especially in Ashkenazi Jews. Attempting to raise HDL cholesterol may (or may not) be useful to mitigate the effects of this SNP.
A allele associated with reduced risk of Alzheimer’s in Chinese Han population.
0.86x risk for Alzheimers
possibly increased risk for Alzheimers
There were 58 Alzheimer’s snps in all. Of those that gave a risk most were average or normal.
From the family history I know it’s definitely not a familial thing.
