This may explain why some with the pathology don't go on to develop symptoms:

Woo hoo- another SNP that may offer protection...
Re: Woo hoo- another SNP that may offer protection...
I am not finding that SNP on snpedia or in the V3 or V4 chip.

Just checked, I'm rs4728029AG. Looks like you can only be A or G phenotype. Which genotype is protective against brain inflammation?
Re: Woo hoo- another SNP that may offer protection...
You BRAVE girls gave me courage to look. I'm AG, like you, Kit. No tears or cheers From what I can glean G is the ancestral allele. The article refers to a mutation. IF the authors are using that term correctly, the golden ticket would be: AA (Please correct me if I'm wrong!)

Oh duh, I found it. The 3 of us are AG.

The Vanderbilt article -- is that the one you mean? -- says:
But it would be good to get the article, or contact the researchers. These university pop summaries are sometimes wrong.

It doesn't say how it relates, but if the mutation is a "marker " of inflammation, it's probably a marker in the "plus" direction (i.e., more inflammation). This would mean the ancestral allele, G, is the better allele.One genetic mutation (rs4728029) was found to relate to both ventricle dilation and cognition and is a marker of neuroinflammation.

G, I think you are right. If anyone is able to get the paper & confirm for us- that would be amazing.

Hmmm, I'm also Heterozygous on this SNP and was born with congenital hydrocephalus...Maybe there's something to this one. There's also a body of work confusing normal pressure hydrocephalus and AD

Julie,
I might have a long life but I hope that I still have some of my brain cells when I'm old.
