TRISOMY 17-18

a congenital disorder marked by low birth weight with many different facial anomalies, a substantial occiput, overlapping of the index finger overtop the third finger, and visual irregularities. Serious cognitive retardation joins the defect, which is caused by non-disjunction of one of the chromosomes within the 17-18 group.
