چکیده

A boy with a duplication 12q24 to qter shows the characteristic phenotype of this chromosome abnormality. The aberration could be analysed as an unbalanced translocation 12/14 de novo by combining different banding techniques with FISH and SKY. Heterologous euchromatin translocations on the heterochromatic short arm regions of the acrocentrics are an extremely rare type of rearrangement.

Subtelomeric rearrangements detected in patients with idiopathic mental retardation.

A screening for submicroscopic rearrangements was performed in 111 patients with idiopathic mental retardation (MR) using fluorescence in situ hybridization (FISH) probes from the subtelomeric regions of all chromosome arms. Ten cryptic rearrangements were found (9%): five de novo deletions; one unbalanced de novo translocation; three unbalanced inherited translocations; and one unbalanced reco...

A new mosaic der(18)t(1;18)(q32.1;q21.3) with developmental delay and facial dysmorphism

We report the case of a 22-month-old boy with a new mosaic partial unbalanced translocation of 1q and 18q. The patient was referred to our Pediatric Department for developmental delay. He showed mild facial dysmorphism, physical growth retardation, a hearing disability, and had a history of patent ductus arteriosus. White matter abnormality on brain magnetic resonance images was also noted. His...

A case with Emanuel syndrome: extra derivative 22 chromosome inherited from the mother

Emanuel syndrome (ES) is a rare chromosomal disorder that is characterized by multiple congenital anomalies and developmental disabilities. Affected children are usually identified in the newborn period as the offspring of balanced (11;22) translocation carriers. Carriers of this balanced translocation usually have no clinical symptoms and are often identified after the birth of offspring with ...

Mosaicism for trisomy 3q arising from an unbalanced, de novo t(3;15).

We report on a 2 1/2 year old girl who is dysmorphic, developmentally delayed, and mosaic for an unbalanced, de novo translocation between chromosomes 3 and 15. The karyotype from peripheral blood lymphocytes is 46,XX (50) and the karyotype from skin fibroblasts is 46,XX (28)/46,XX,der(15)t(3;15)(q11;p11) (23). The mechanism for the generation of this unbalanced, de novo translocation is discus...

Autism Spectrum Disorder in a Girl with a De Novo X;19 Balanced Translocation

Balanced X-autosome translocations are rare, and female carriers are a clinically heterogeneous group of patients, with phenotypically normal women, history of recurrent miscarriage, gonadal dysfunction, X-linked disorders or congenital abnormalities, and/or developmental delay. We investigated a patient with a de novo X;19 translocation. The six-year-old girl has been evaluated due to hyperact...
