(Submitter supplied) The cause of mental retardation in one-third to one-half of all affected individuals is unknown. Microscopically-detectable chromosomal abnormalities are the most frequent recognized cause, but gain or loss of chromosomal segments that are too small to be seen by conventional cytogenetic analysis has been found to be another important cause. Array-based methods offer a practical means of performing a high-resolution survey of the entire genome for submicroscopic copy number variants. more...

(Submitter supplied) Affymetrix submissions are typically submitted to GEO using the GEOarchive method described at http://www.ncbi.nlm.nih.gov/projects/geo/info/geo_affy.html The GeneChip® Mapping 100K Set is the first in a family of products for whole-genome association studies. It is comprised of a set of two arrays that enable genotyping of greater than 100,000 SNPs with a single primer. copy number analysis mean marker distance of 26 kb provides both copy number and allele specific information Protocol: see manufacturer's web site
