چکیده

A malformed male infant with pure partial trisomy 12q (q24.1 leads to qter), resulting from an unbalanced segregation of a paternal balanced translocation t(2;12)(q37;q24.1), is described. The cytogenetic and clinical abnormalities of the proband are compared with those of four previously reported cases of partial trisomy 12q, two of which also appear to have pure trisomy of segment 12q24.1 leads to 12 qter.

Partial 10q trisomy with partial 12q monosomy.

A case of partial trisomy 10q with partial monosomy 12q is reported. The chromosomal abnormalities resulted from a paternal balanced, reciprocal translocation involving chromosomes 10 and 12, which, to the best of our knowledge, has not been previously described.

Mosaicism for duplication 12q (12q13-->12q21.2) accompanied by a pericentric inversion in a dysmorphic female infant.

While several case reports describe partial trisomy 12qter, reports of interstitial 12q duplications are extremely rare. We present here the clinical findings in a female infant with mosaicism for a duplication of chromosome 12q13.3→12q21.2 accompanied by a pericentric inversion (12)(p13.3q21.2). No other cases with an interstitial duplication for this region have been reported. The female infa...

A third case of de novo partial trisomy 4p.

Interestingly, the previously reported patient with a different but overlapping deletion of chromosome 12 long arm (q13.3-q21.1) and the subject of this report have only a few features in common (table). The deletion in each includes the portion 12q13.3 to q21. 1. It is unclear whether the small difference in the portion of 12q deleted accounts for the fact that they do not resemble each other ...

Endocrine abnormalities in a patient with partial trisomy 4q.

Partial trisomy of the long arm of chromosome 4, usually resulting from a familial segregation of a balanced translocation, has been described in a number of patients. This report describes the genetic and endocrine findings in a 16 year old 46,XY,12q+ mentally retarded male. The banding pattern of the extra chromatin material from this de novo unbalanced translocation shows that the distal seg...

Report of a Case with Trisomy 9 Mosaicism

Trisomy 9 is a rare chromosome disorder with high neonatal mortality. It is often seen in mosaic form. Most patients who survive are severely mentally retarded. The main features of this syndrome are "bulbous" nose, microphthalmia, dislocated limbs, and other anomalies of skeletal, cardiac, genitourinary, and central nervous system. Most patients have developmental and cognitive impairment. Pat...
