Partial Trisomy 9p(p22→pter) from a Maternal Translocation 4q35 and 9p22.
We present clinical and cytogenetic data on a 7-year-old female child with partial trisomy for 9p22→9pter as a result of a maternal balanced reciprocal translocation. Her karyotype was ascertained as 46,XX,dec(4)t(4;9)(q35; p22)mat. The father had a normal karyotype, while the mother had an apparently balanced translocation involving chromosomes 4 and 9 [46,XX,t(4;9)(q35;p22)]. This case will be briefly compared with other published cases of a similar translocation.
