title: Partial 4q duplication due to inherited der(13),t(4;13)(q26;q34)mat in a girl with a deficiency of factor X.
abstract: A girl with mental retardation had a partial trisomy 4q. The chromosome aberration originated from a maternal balanced translocation t(4;13)(q26;q34). The value of Factor X was half the normal value, raising the question of the location of a gene related to the production of Factor X on chromosome 4.
