Prenatal diagnosis of a case of tetrasomy 9p.
A male fetus with tetrasomy 9p [47,XY, + i(9p)] is presented. The cytogenetic interpretation of the marker chromosome was confirmed by assessing the activity of the enzyme galactose I-phosphate uridyl transferase. The clinical findings of the case show features in common with previously reported cases.
