US Patent:

20050260665, Nov 24, 2005

Filed:

May 19, 2005

Appl. No.:

11/134133

Inventors:

Mansoor Mohammed - Irvine CA, US
Natasa Dzidic - Laguna Beach CA, US
Christopher McCaskill - Ladera Ranch CA, US
Jaeweon Kim - Carlsbad CA, US

International Classification:

C12Q001/68

US Classification:

435006000

Abstract:

The present invention provides methods of detecting and mapping chromosomal or genetic abnormalities associated with various diseases or with predisposition to various diseases, or to detecting the phenomena of large scale copy number variants. In particular, the present invention provides advanced methods of performing array-based comparative hybridization that allow reproducibility between samples and enhanced sensitivity by using the same detectable label for both test sample and reference sample nucleic acids. Invention methods are useful for the detection or diagnosis of particular disease conditions such as cancer, and detecting predisposition to cancer based on detection of chromosomal or genetic abnormalities and gene expression level. Invention methods are also useful for the detection or diagnosis of hereditary genetic disorders or predisposition thereto, especially in prenatal samples. Moreover, invention methods are also useful for the detection or diagnosis of de novo genetic aberrations associated with post-natal developmental abnormalities.

Appl. No.:

11/883150

Inventors:

Mansoor S. Mohammed - Mission Viejo CA, US
Natasa Dzidic - San Clemente CA, US
Christopher McCaskill - Ladera Ranch CA, US

International Classification:

C40B 30/04
C12Q 1/68

US Classification:

506 9, 435 6

Abstract:

Disclosed is a method for performing nucleic acid hybridization assays, such as assays used for detecting and mapping chromosomal or genetic abnormalities associated with various diseases or associated with predisposition to various diseases. In a particular aspect, the present method relates to the use of rapid nucleic acid hybridization methods for comparing nucleic acid segments of one genome to corresponding nucleic acid segments in another genome(s).
