region in TERT. In addition, SH2B3 was suggestive
(p<10-6) in the MPN analysis and showed genome-wide
significance in the analysis of V617F carriers among the
control group.
“Motivated by the consistency of results from these
two analyses,” Dr. Hinds and colleagues then performed
a combined GWAS of the 726 MPN cases plus the V617F
carriers in the control population (n=1,223), compared with the remaining V617F non-carrier controls
(n=252,150).
The strongest signal was in the germline JAK2 46/1
haplotype (rs59384377; OR=2.46; p=6.6x10–89), which has
previously been associated with V617F-positive MPN.
This variant had the strongest association and the highest
prevalence among patients with PV, but the smallest association and the lowest prevalence in ET.
Genome-wide significant associations were also
identified in:
• TERT variant rs7705526 (OR=1.8; p=1.1x10–32)
• SH2B3 variant rs7310615 (OR=1.4; p=3.1×10−14)
• upstream TET2 variant rs1548483 (OR=2.0;
p=2.0×10−9)
These associations were confirmed in an analysis of the
446 JAK2 V617F carriers with the 169,021 V617F noncarriers in the replication cohort.
Then, in a joint analysis of the combined GWAS and
replication results, Dr. Hinds and colleagues identified
