TABLE 2.

Mutation frequency by area of geographic residency

	Urban	Rural	p Value
	n (%)	n (%)
ASXL1	2 (2%)	4 (5.9%)	.2362
DNMT3a	19 (20%)	9 (13.2%)	.2589
IDH1	5 (5.3%)	4 (5.9%)	1.0000
IDH2	6 (6.3%)	2 (2.9%)	.4705
NPM1	18 (19%)	9 (13.2%)	.3334
NRAS	7 (7.4%)	4 (5.9%)	.7634
TET2	3 (3.2%)	1 (1.5%)	.6411
TP53	4 (4.2%)	5 (7.4%)	.4924
FLT3	8 (8.4%)	7 (10.3%)	.6833

Note: This table describes the mutation frequency stratified by area of residency (urban or rural). There was no statistically significant difference in the frequency of any mutations between the cohorts. FLT3 incorporates both internal tandem duplication and tyrosine kinase domain mutations.
