Demographic and skin type data in studied population

DNA modification /Gene	n	Age (Mean ± SD)	Gender (Male/Female)	Skin Type (number of individuals for each skin type)
Global DNA methylation and hydroxymethylation	24	57,9 ± 21,6	11/13	09-type III; 10-type IV; 05-type V
miR-9-1	17	57,8 ± 20,9	7/10	06-type III; 07-type IV; 04-type V
miR-9-3	21	56,1 ± 21,3	10/11	08-type III; 09-type IV; 04-type V
MTHFR	14	58,5 ± 21,8	5/9	06-type III; 04-type IV; 04-type V

Type III: light brown, type IV: moderate brown and type V: dark brown. We collected samples from 24 corpses, but some samples are not available for amplification or showed no fragments after PCR amplification, and were excluded from the study.
