    A 32 week, small for dates baby with aplasia cutis congenita had an unbalanced translocation, being monosomic for distal 12q and trisomic for distal 1q. As far as is known, the association between extensive skin defects and a chromosomal abnormality has not been reported before. Keratin genes have been located in a different area of 12q, but this case may indicate other candidate areas to explore. Karyotyping should be undertaken in all babies with aplasia cutis.
