Supplementary Material for: Noninvasive Prenatal Detection of Trisomy 21 by Targeted Semiconductor Sequencing: A Technical Feasibility Study
<p><b><i>Objective:</i></b> To develop an alternate noninvasive prenatal
testing method for the assessment of trisomy 21 (T21) using a targeted
semiconductor sequencing approach. <b><i>Methods:</i></b> A customized
AmpliSeq panel was designed with 1,067 primer pairs targeting specific
regions on chromosomes 21, 18, 13, and others. A total of 235 samples,
including 30 affected with T21, were sequenced with an Ion Torrent
Proton sequencer, and a method was developed for assessing the
probability of fetal aneuploidy via derivation of a risk score. <b><i>Results:</i></b>
Application of the derived risk score yields a bimodal distribution,
with the affected samples clustering near 1.0 and the unaffected near 0.
For a risk score cutoff of 0.345, above which all would be considered
at “high risk,” all 30 T21-positive pregnancies were correctly predicted
to be affected, and 199 of the 205 non-T21 samples were correctly
predicted. The average hands-on time spent on library preparation and
sequencing was 19 h in total, and the average number of reads of
sequence obtained was 3.75 million per sample. <b><i>Conclusion:</i></b>
With the described targeted sequencing approach on the semiconductor
platform using a custom-designed library and a probabilistic statistical
approach, we have demonstrated the feasibility of an alternate method
of assessment for fetal T21.</p
