Results of DNA extraction and paired comparison of genotyping completion rates and concordance for blood and buccal samples

Paired DNA samples (n = 23 pairs)
Buffy coatBuccal cells
DNA yield median (range; ng/μL)49.6 (0.55-74.68)44.4 (14.32-66.04)
Genotyping completion rate, % (95% CI)*99.63 (99.43-99.84)99.44 (99.14-99.72)
Concordance, % (95% CI)99.96 (99.93-99.99)
  • * Percent based on 315,314 SNPs using the HumanHap 300 chip; P value for the difference in completion rates by sample type, 0.15.
