微阵列比较基因组杂交技术

Chromosomal microarray (CMA) is increasingly utilized for genetic testing of individuals with unexplained developmental delay/intellectual disability (DD/ID), autism spectrum disorders (ASD), or multiple congenital anomalies (MCA). CMA offers a much higher diagnostic yield (15%~20%) for genetic testing of individuals with unexplained DD/ID, ASD, or MCA than a G-banded karyotype (3%~5%), primarily because of its higher sensitivity for submicroscopic deletions and duplications.      AffymetrixGeneChip® System 3000Dx v.2 introduced by KingMed Diagnostics is the latest CMA technology platform and certified by FDA/CFDA/CE. CytoScan Dx Assay is the first FDA-cleared test that is intended for the postnatal detection and analyzes the whole genome in a single assay at unprecedented resolution, which significantly improves diagnostic capability.
