[Report on a variant of the fetal-face-syndrome with acral dysostosis (Robinow-Silverman-Smith-Syndrome) (author's transl)].

Besides the typical clinical symptoms of Robinow-Silverman-Smith-syndrome our patient shows a severe dislocation of the hip, feeding difficulties, and a marked morphological and mental retardation. The karyotype was normal, we found a normal banding pattern of all chromosomes (G-banding). In the family of our proband we observed minor skeletal abnormalities.
