A 13-year old boy with 9p- is reported. He had many features in common with previous 9p- cases, as well as several distinctive features including polydactyly and precocious puberty. Cytogenetic studies revealed a de novo deletion distal to band 9p22, which was the reported site of chromosome break in 9 of the 10 previous 9p- cases. Evaluation of the human GALT enzyme suggests that its locus is not on the deleted segment.
