Abstract excerpt

OBJECTIVE: We present high-level mosaicism for 45,X in 45,X/46,X,+mar at amniocentesis in a pregnancy associated with positive non-invasive prenatal testing (NIPT) for Turner syndrome, normal male external genitalia and positive SRY in the fetus, a favorable fetal outcome, postnatal decrease of the 45,X cell line and cytogenetic discrepancy in various tissues. CASE REPORT: A 35-year-old, gravida 2, para 1, woman...
