Investigation of a cluster of children with Down Syndrome born to mothers who had attended a school in Dundalk, Ireland. g dean, n c nevin, m mikkelsen, g karadima, m b petersen, m kelly, j o'sullivan. 2000;57:793-804.
Three small typographical errors occurred in table 1 of this paper which gave details of the cases constituting the cluster.
For case number 3 the parity should be 2 and not 1, and the maternal age should be 25 years and not 26 years.
For case number 5 the sex should be female (F), not male (M). These changes do not affect the remainder of the paper in anyway or the conclusions of the study.
