A LOT of genetic data is out there … and more coming all the time … easy to get excited about, but hard to make sense of. Here’s an epic story of just one SNP.
One of the best research teams in the business performed a genomewide association study (GWAS) of neuroticism in 1,227 US Caucasion participants and found associations (P values of 10−5 to 10−6) with several markers – including rs7151262 in the MAMDC1 gene. Later they replicated the finding in a German sample of 1,880 (P values in the same directions 0.006–0.025).
Very exciting to ponder the ways in which this SNP might relate to the development of brain systems that process emotional information!
More recently, they attempted another replication of the MAMDC1 gene for association with neuroticism in 2,722 US Caucasion participants. This time they report, “the current analysis failed to detect a significant association signal“.
Some 5,829 people were involved in the research and the data suggest that rs7151262 may or may not contribute to one’s neurotic tendencies. If you knew your rs7151262 genotype would it change the way you think about yourself?
I don’t know … the confusion over the (+) vs. (-) association data would make me … well, neurotic.
