Microarray analysis can assess several different chromosomal regions/ genes at the same time and can identify changes which can not be detected by both cytogenetics and FISH.
Microarray with mutltiple gene regions on a single chip
Next generation sequencing
It is a low cost and high-throughput DNA sequencing producing millions of sequences concurrently in a very short time
Whole genome Sequencing
It determines the complete DNA sequence of an individual in a single time in a cost effective method. The information about all genes is obtained from this method.
Exome sequencing
It is a technique for sequencing all the coding genes in a genome (exome). A gene can be studied in particular which is responsible for a specific condition.
