Positive predictive value (PPV) for fetal confirmation was 5.1% (4\/79) and diagnostic yield was 8.9% (7\/79) when uniparental disomy\/runs of homozygosity (UPD\/ROH) findings were included. Follow\u2010up of 104 pregnancies included 63 uncomplicated pregnancies, 34 adverse pregnancy outcomes, and 7 terminations of pregnancy (TOP). In the primary analysis of 93 pregnancies, the TMR showed poor discrimination for adverse outcomes (AUC 0.643, 95% CI 0.531\u20130.756).
