We report a female patient with a 46,XX,der(8)t(1;8) (q42.1;p23.3) kar
yotype who had a mild phenotype characterised by a few subtle dysmorph
ic features and mild developmental retardation, probably resulting fro
m trisomy 1q42-->qter. The deletion on the short arm of the chromosome
8 appeared to be confined to the distal chromosomal segment.
