Comment[ArrayExpressAccession] E-MTAB-1794 MAGE-TAB Version 1.1 Investigation Title Amplicon sequencing of different regions of metastatic melanomas Comment[Submitted Name] Amplicon sequencing of different regions of metastatic melanomas Experiment Description Genetic heterogeneity can provide tumors with opportunities for therapy evasion, however the degree of genetic heterogeneity within metastatic melanomas has not been thoroughly investigated. We therefore isolated DNA from different regions of formalin fixed paraffin embedded metastatic melanoma tissue samples and subjected them to amplicon sequencing-based profiling of mutations in a panel of well known cancer genes using the Ion Ampliseq Cancer Panel.

Publication Status Protocol Name P-MTAB-33971 P-MTAB-33972 P-MTAB-33973 P-MTAB-33974 P-MTAB-33975 Protocol Type treatment protocol nucleic acid extraction protocol nucleic acid library construction protocol nucleic acid sequencing protocol high throughput sequence alignment protocol Protocol Description Three mm cores were removed from formalin fixed paraffin embedded tissue blocks, and the top 2mm removed with a sterile scalpel blade. DNA was extracted from tissue core fragments using a 24 hour proteinase K digestion (Arcturus Picopure DNA Extraction kit), follwed by clean up using DNEasy columns (Qiagen). Libraries were prepared using the Ion Ampliseq Cancer Panel kit (Life Technologies) and the Ion AmpliSeq Library Kit, after which individual libraries were barcoded using the Ion Xpress Barcode Adaptor Kit (Life Technologies) Eight barcoded libraries were pooled for each run, and sequenced on Ion 318 chips Reads were aligned to HG19 using TMAP. Variants were identified using the Ion Variant Caller plug-in; all settings default with the exception of a SNP QV minimum of 14.
