Abstract
Two siblings with an unbalanced cytogenetic composition are described: a brother with
partial trisomy 5p and distal 15q microdeletion, and a sister with partial monosomy
5p and distal 15q microduplication, resulting from a familial balanced translocation
46,XY; t(5;15)(p14.2;q26.2). To our best knowledge, there are no previous clinical
and cytogenetic reports in the literature describing a family with concomitant presence
of such a unique mirror combination. Clinical features of pure imbalances and the
effects of their combination are discussed.
