Autosomal aneuploidies occurring in chromosomes other than 13, 18, and 21 and sex chromosomal aneuploidies
are referred to as ‘Rare autosomal aneuploidies’ (RAAs). A prenatal incidence of 0.41% is noted for RAAs on chorionic villus sampling (CVS) procedures. Aneuploidies in autosomes other than 13, 18, and 21 and sex chromosomal aneuploidies may result in increased fetal-placental diseases such as non-viable pregnancy, early miscarriage, intrauterine fetal growth restriction, uniparental disomy, multiple congenital anomalies, fetal demise, or normal live birth [1].
