A 40 year-old dysmorphic and mentally retarded female is reported with a de novo unbalanced chromosomal rearrangement (karyotype: 46,XX,der(8)t(8;13)(p23;q123),idic(13)(pter-->q123: q123-->pter) resulting in an isodicentric chromosome 13 and a double aneusomy including partial trisomy 13 (13pter-q123) and distal monosomy 8p (8pter-p23). The main clinical findings consist of developmental/mental retardation, behavioural disturbances and minor congenital defects, not consistent with the clinical pattern of either of the two aneusomies. A mechanism for the chromosome rearrangement is proposed and the absence of specific physical findings in the present patient is discussed in the light of the available literature data.
