Comparative Genomic Hybridization (CGH)

Microdeletion and Microduplication Analysis of Chinese Conotruncal Defects Patients with Targeted Array Comparative Genomic Hybridization

OBJECTIVE The current study aimed to develop a reliable targeted array comparative genomic hybridization (aCGH) to detect microdeletions and microduplications in congenital conotruncal defects (CTDs), especially on 22q11.2 region, and for some other chromosomal aberrations, such as 5p15-5p, 7q11.23 and 4p16.3. METHODS Twenty-seven patients with CTDs, including 12 pulmonary atresia (PA), 10 do...

Identification of Genomic Aberrations by Array Comparative Genomic Hybridization in Patients with Aortic Dissections

BACKGROUND The aim of the present study was to identify chromosomal loci that contribute to the pathogenesis of aortic dissection (AD) in a Korean population using array comparative genomic hybridization (CGH) and to confirm the results using real-time polymerase chain reaction (PCR). MATERIALS AND METHODS Eighteen patients with ADs were enrolled in this study. Genomic DNA was extracted from ...

Comparative genomic hybridization analysis of adrenocortical tumors of childhood.

Although several genes have been investigated in adrenal tumorigenesis, the genetic background of adrenocortical tumors (ACT) remains poorly characterized. In southern Brazil, the annual incidence of ACT is unusually high, ranging from 3.4-4.2/million children, compared with a worldwide incidence of 0.3/million children younger than 15 yr. Environmental factors have been implicated because the ...

Comparative genomic hybridization for molecular cytogenetic analysis of solid tumors.

Comparative genomic hybridization produces a map of DNA sequence copy number as a function of chromosomal location throughout the entire genome. Differentially labeled test DNA and normal reference DNA are hybridized simultaneously to normal chromosome spreads. The hybridization is detected with two different fluorochromes. Regions of gain or loss of DNA sequences, such as deletions, duplicatio...
