Partial trisomy 3p and partial monosomy 11q associated with double outlet right ventricle and septum pellucidum et vergae: a case report.

Su Partial trisomy 3p and partial monosomy 11q are rare chromosomal disorders with a deletion of part of chromosome 11 combined with a duplication of part of chromosome 3. These are usually inherited from a parent who carries a balanced translocation involving chromosome 3, which can result in the unbalanced translocation trisomy 3p in a child. In this paper, we report a newborn who has dysmorphic facial features, double outlet right ventricle, hypotonia, hypospadias, neonatal thrombocytopenia, hydroureteronephrosis, talipes equinovarus and septum pellucidum et vergae. Cytogenetic investigation revealed 46,XY,der(11)t(3;11)(p22.2;q23.3) and the karyotype of his father showed a balanced translocation, 46XY,t(3;11)(p22.2;p23.3).
