%X Trisomy 7 is the most common observed type of rare autosomal trisomies (RATs) detected at expanded genome-wide non-invasive prenatal testing (NIPT). Genetic counseling of NIPT trisomy 7-positive pregnancies remains to be not easy because the parents may worry about the likelihood of adverse pregnancy outcomes, fetal abnormality and the necessity of invasive procedures for confirmation of fetal mosaic trisomy 7 and uniparental disomy (UPD) 7.
