Both known and model RefSeq records may be associated with the same locus. A portion of the ‘Genomic regions, transcripts, and products’ section of the Gene record for human GSTZ1 (NCBI GeneID 2954) is shown. Chromosome 14 coordinates corresponding to annotation of assembly GRCh13.p13 (NC_000014.8), NCBI annotation release 105 are shown at the top. The gene is associated with three known RefSeq transcripts (e.g. NM_145870.2, NM_145871.2 and NM_001513.3) and three model transcripts (e.g. XM_005267557.1, XM_005267558.1 and XM_005267559.1). The first exon of the overlapping POMT2 gene is also visible in this display. Supplementing curated RefSeqs (NM, NR, or NP prefixes) with model RefSeqs (XM, XR and XP accessions) enables better representation of alternative splice variants and exons.
