This was a genome-wide association study of total plasma fatty acids with 495,343 SNPs genotyped using Illumina 550K. 

Fatty acids measured:
The fatty acids analyzed include alpha linolenic acid


alpha-linolenic acid (ALA)
eicosapentanoic acid (EPA)
docosahexanoic acid (DHA)
linoleic acid (LA)
eicosadienoic acid (EDA)
arachidonic acid (AA)
