. Using genome-wide association data from three studies (
n
= 8,816 that included 2,758 individuals from the Diabetes Genetics Initiative specific to the current paper as well as 1,874 individuals from the FUSION study of type 2 diabetes and 4,184 individuals from the SardiNIA study of aging-associated variables reported in a companion paper in this issue

) and targeted replication association analyses in up to 18,554 independent participants, we show that common SNPs at 18 loci are reproducibly associated with concentrations of low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and/or triglycerides. Six of these loci are new (
P
< 5 × 10
−8
for each new locus). Of the six newly identified chromosomal regions, two were associated with LDL cholesterol (1p13 near
CELSR2
,
PSRC1
and
SORT1
and 19p13 near
CILP2
and
PBX4
), one with HDL cholesterol (1q42 in
GALNT2
) and five with triglycerides (7q11 near
TBL2
and
MLXIPL
, 8q24 near
TRIB1
, 1q42 in
GALNT2
, 19p13 near
CILP2
and
PBX4
and 1p31 near
ANGPTL3
). At 1p13, the LDL-associated SNP was also strongly correlated with
CELSR2
,
PSRC1
, and
SORT1
transcript levels in human liver, and a proxy for this SNP was recently shown to affect risk for coronary artery disease

. Understanding the molecular, cellular and clinical consequences of the newly identified loci may inform therapy and clinical care. |
