Prion protein, a sialoglycoprotein with neuroprotective properties on oxidative stress damage, has been related with the mechanisms leading to migraine. In the present case-control study, we investigated the correlation between the common methionine/valine polymorphism at codon 129 within the prion protein gene (PRNP) and migraine. Genotyping of PRNP V129M variant was performed in 384 migraine patients and 185 age-, sex-, and race-ethnicity-matched healthy controls. The frequencies of the PRNP V129M genotype did not differ significantly between migraineurs and controls. The frequencies of 129VV genotype were significantly higher in patients with earlier age at migraine onset. No correlation was found between PRNP 129 genotype and demographics, and other clinical migraine features. Our data suggest that the PRNP 129VV polymorphism is not a direct migraine risk factor but is significantly associated with an earlier onset of the disease.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 February 2013.
All research outputs
#27,763,431
of 34,410,315 outputs
Outputs from Headache: The Journal of Head & Face Pain
#4,016
of 4,484 outputs
Outputs of similar age
#283,376
of 350,099 outputs
Outputs of similar age from Headache: The Journal of Head & Face Pain
#26
of 37 outputs
Altmetric has tracked 34,410,315 research outputs across all sources so far. This one is in the 16th percentile – i.e., 16% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,484 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 15.6. This one is in the 9th percentile – i.e., 9% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 350,099 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 37 others from the same source and published within six weeks on either side of this one. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
