a trend toward significanceP = 5.5 × 10 −8
However, two variants on chromosome 17 showed a trend toward significance in the Sierra Leone cohort (Table 1 and Extended Data Fig. 2e ). rs73397758 ( P = 5.5 × 10 −8 , odds ratio (OR) = 9.16) is ~350 KB (kilobase pairs) downstream of the gene CASC17 , a long non-coding RNA named for a genetic association with prostate cancer 37 , and 570 KB upstream of KCNJ2 , a potassium inwardly rectifying channel 38 . rs143130878 ( P = 1.1 × 10 −7 , OR = 6.87) resides 62,472 base pairs downstream of the gene CCT6B 39 , which is a member of the molecular chaperone (TRiC) family that has been shown to regulate the replication of arenaviruses, including LASV 40 .
