Molecular analysis of a partial deletion of 22q in a central nervous system rhabdoid tumor

Genes Chromosomes Cancer. 1992 Sep;5(2):104-8. doi: 10.1002/gcc.2870050203.

Abstract

We previously reported the non-random occurrence of monosomy 22 in rhabdoid or atypical teratoid tumors of the brain in three young children. We now present cytogenetic and molecular studies of an additional rhabdoid tumor with the karyotype 46,XX,-9,-22,+i(1q),+der(22)t(9;22)(p13;q11)/45,XX,-9,-10,- 22,+i(1q),+der(22)t(9;22)(p13;q11). These studies further demonstrate the involvement of chromosome 22, and they begin to define the critical region containing a gene or genes involved in the development or progression of rhabdoid tumors of the brain.
