Quest Diagnostics Discovers New Genetic Mutations Affecting Cystic Fibrosis...(Diagnostics is one of the leading provid...),Health

Date:4/27/2009

Diagnostics is one of the leading providers of pre- and post-natal and carrier genetic screening. In March 2009, the company announced that it operates one of only three laboratories approved by the state of New York to perform microarray-based comparative genomic hybridization (aCGH) postnatal testing, using its ClariSure aCGH postnatal test, for copy-number chromosomal abnormalities implicated in mental retardation, birth defects, and autism spectrum and developmental disorders. The company also provides a broad-based population screening technology designed to help determine whether parents are carriers of the genetic mutation that causes Fragile X syndrome, the most common form of inherited mental retardation. In 2002, the company launched its CF Complete test, which enables physicians to identify rare mutations that cause CF by sequencing the complete coding sequence of the cystic fibrosis gene.
