Provided herein are methods for miRNA profiling for the diagnosis, prognosis, and management of melanoma and differentiation of melanoma from nevi.

MicroRNA profiling for diagnosis of dysplastic nevi and melanoma

Microrna profiling for diagnosis of dysplastic nevi and melanoma

Provided are methods of determining differences between nucleic acids in a test sample and a reference sample. In certain embodiments the methods are used for 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, provided are 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.
