## Involvement of 12q12-13 Is a Nonrandom Chromosome Change in Renal Oncocytoma To the Editors: Cytogenetically, renal oncocytomas constitute a heterogeneous group of benign renal tumors with at least two different subgroups: 1) those with coincident loss of the Y chromosome and chromosome 1, and

✦ Synopsis
Cytogenetic analysis of a recurrent periosteal chondroma revealed nonreciprocal translocations of both chromosomal segments 12q I 3 +qter, from one chromosome I 2 to 7q32 and from the homologous chromosome I 2 to I6q22. The remaining parts of the two chromosomes I 2 formed a dicentric chromosome. This is the second reported chondroma with a 12q 13-I 5 rearrangement, and changes of t.his chromosome region consequently seem to be nonrandom occurrences in chondromas.

## Abstract Microcell‐mediated chromosome transfer (MMCT) is a powerful genetic technique that permits the transfer of a single chromosome from one mammalian cell to another. The utility of MMCT for gene mapping strategies is critically dependent on the careful characterization of the chromosomes b
We report on a girl with the typical trisomy 9p syndrome who had an additional E-sized metacentric chromosome.

Multiple endocrine neoplasia type 1 syndrome (MEN1, MIM 131100), an autosomal dominant disease, is characterized by parathyroid hyperplasia, pancreatic endocrine tumors, and pituitary adenomas. These tumors also occur sporadically. Both the familial (MEN1) and the sporadic tumors reveal loss of hete
