The lack of a nose bone isn't a definite indicator that your baby has Down's syndrome. Babies with normal chromosomes can also appear to be missing a nasal bone on an ultrasound scan, When the nasal bone is absent at 11 to 12 weeks, while the other ultrasound markers and serum biochemistry are normal; a follow up scan after a week is suggested. The incidence of an absent nasal bone is related to nuchal translucency (NT), crown rump length (CRL), and ethnic origin, as well as aneuploidy.
