Triplication of distal chromosome 10q.
نویسندگان
چکیده
We describe a patient with a de novo chromosomal aberration with karyotype 46,XY,10q+, presenting clinical features of partial duplication of distal chromosome 10q. Further studies using microsatellites and FISH showed a triplication of distal chromosome 10q. The rearrangement involved both maternal homologues and the middle chromosomal 10q fragment of the triplication was inverted, similar to previously reported chromosomal triplications. Chromosomal triplications may be more frequent than assumed and may share a common molecular mechanism.

Background: Here we describe a new case of partial distal 10q trisomy in a 6-year-old Iranian girl from healthy parents with mental, growth, and psychomotor retardations. Methods: Additional clinical features include dysmorphic craniofacial features, microcephaly, bilateral hydronephrosis without heart problems, small and rotated low-set ears, bow-shaped mouth, abnormal teeth, short neck, an...

Array comparative genomic hybridization studies were performed to further characterize cytogenetic abnormalities found originally by karyotype and fluorescence in situ hybridization in five clinical cases of distal 10q deletions, including several with complex cytogenetic rearrangements and one with a partial male-to-female sex-reversal phenotype. These results have enabled us to narrow the pre...

A female infant with karyotype 46,XX,rec(10),dup p inv(10)(p11.2q25.2)mat is presented. She had both duplication of 10p and deletion of distal 10q, but only had the constellation of specific features characteristic of duplication of 10p.

Trisomy 10 has been detected in spontaneous abortions and prenatally. Although there are no reports of duplication of the whole long arm of chromosome 10, duplication of 10q21–qter has been found in a stillborn infant. Trisomy of more distal 10q is associated with a characteristic syndrome and has been described in many cases which almost always are familial, 4 but patients with trisomy of the ...
