11, 14] Moreover, Prenatal BoBs[TM] has some limitations in the detection of polyploidies (triploidies and tetraploidies), [5, 9] which account for nearly 16% of abnormalities found by conventional karyotyping of POC.
These changes include chromosomal abnormalities (7,8), as deletions in region 6q15-q21 of chromosome 6, pericentric in version of chromosome 9 inv(9)(p11q13), loss of chromosomes 3p, 6p, 6q, 9q, 11p, 13q, 17p13 y 17q, trisomies 12, 7 and 8, monosomies X (A, B, C, D, E, F, G, H) and polyploidies (with randomly positioned chromosomes) (9-16), which usually precede chromosomal abnormalities.
