Abstract
The female carrier of a de novo interstitial deletion 9q [karyotype 46,XX,del(9)(q31.2q33.1)] was followed up over a period of more than 20 years. She shows facial dysmorphisms and significant growth retardation. Motor abilities are restricted by muscular hypotonia and malposition of the feet. She has mental retardation. There was no speech development and phases of autism were reported. By analyses with FISH and short tandem repeat markers, the interstitial deletion was confirmed and characterized to span 9q31.2q33.1, comprising at least 7.07 Mb. The aberration is of paternal origin. © 2008 Wiley‐Liss, Inc.
