Protein Coding Features based on feature's gene biotype from the comprehensive set of gene annotations created on GRCh38 and mapped to GRCh37 by GENCODE (v34lift37). All non-protein coding features have been removed. Some annotations were obtained from GENCODE v19 when mapping failed. Scaffoldings, assenbly patches, and alternative loci are NOT included. Features include: CDS, Selenocysteine, UTR, exon, gene, start_codon, stop_codon, transcript.
