The Madrid-based genetic diagnostics center, which is authorized by Madrid's health department and is accredited by the Spanish Association of Human Genetics, becomes Agilent's first certified service provider in the country.

Affymetrix expects CytoScan HD to "set performance standards" in the cytogenetics research market, and believes that the new chip will have the "broadest degree of coverage for constitutional and cancer applications."

The new high-density chips could give Roche NimbleGen an advantage in the market for clinical research arrays, such as cytogenetics, where it competes against Affymetrix, Agilent Technologies, and Illumina.

Array technology has enabled cytogeneticists to inadvertently identify children born of incestuous relationships, a fact that has caused researchers at Baylor College of Medicine to call for official guidelines on handling such cases.

Roche NimbleGen said that in the second half of 2011 it plans to double the density of its arrays for comparative genomic hybridization to 4.2 million markers, and will also introduce CGH/SNP arrays containing 2.1 million markers.

Lineagen's new chromosomal microarray testing and genetic-counseling service, dubbed FirstStepDx, aims to appeal to pediatricians who are charged with treating children with possible autism spectrum disorder or developmental delay.

BioArray News spoke with Ledbetter about his new role at Geisinger, as well as the continued activities of the International Standards for Cytogenomic Arrays Consortium.

In a year when the word "sequencing" was on everybody's lips, microarray-based applications advanced steadily into routine clinical use.

Officials from BlueGnome and the CCMC said they hope the wider availability of the arrays will spur cancer cytogenetics researchers to adopt the consortium's design and further the efforts of the CCMC to set standards for using arrays in cytogenetics.

Keener than ever to establish itself as a key genomic research tools provider for in vitro fertilization laboratories, BlueGnome recently rolled out a new offering to help doctors better understand the biological factors underlying recurrent miscarriage.
