Evolving applications of microarray technology in postnatal diagnosis (review)

Abstract

Microarray-based cytogenetics is revealing the tremendous fluidity and complexity of the human genome, and is starting to illustrate the implications of genomic variability with respect to human health and disease. In the last few years, the robustness of array-based technologies has provided accurate diagnosis and appropriate clinical management in a timely and efficient manner for identifying genomic defects of congenital and developmental abnormalities including developmental delay (DD), intellectual disability (ID), autism spectrum disorders (ASD) and/or multiple congenital anomalies (MCA). The implementation of this technology in these categories of disorders has been thoroughly evaluated and is now recommended as a first-line diagnostic approach for clinically suspected genetic disorders. However, clinical application of array-CGH in postnatal evaluation raises the debate of whether array-CGH will replace traditional cytogenetics in the near future and whether there is still a role for karyotyping and FISH. In this article, we therefore review the current status of array-based technology use for postnatal diagnosis and predict that it will replace standard cytogenetics as a first-line test for clinical evaluation in these...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
