The ideal scenario would be finding a single genetic variant that perfectly describes a patient phenotype, however, this is very rarely the case. The signal processing differs between platforms, Illumina instruments convert fluorescent signals into nucleotide base calls, whereas Ion Torrent instruments process signals in the form of a pH change converted to voltage (Figure 2). Depending on the case they may even ask for genetic profiles of the parents to understand the inheritance of potential disease alleles. sample type. Other sources of information used to annotate variants include population frequency databases (1000Genome), oncology databases (COSMIC) and pharmacogenomics databases (PharmGKB). After reading the forward DNA strand, the reads are washed away, and the process repeats for the reverse WORKFLOW OF OUR NGS DATA ANALYSIS SERVICE.
