**GencodeV41\_Name:** Gencode v41 Gene Name: Target gene names from the RefSeq database. Multiple listings of the same gene name indicate splice variants.
**GencodeV41\_Accession:** Gencode v41 Transcript ID: The RefSeq accession numbers of the target transcripts. Accession numbers are in the same order as the target gene transcripts.
