RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: VALIDATED

Description

Transcript Variant: This variant (6) differs in both UTR's and the coding region and uses an alternate start codon, compared to variant 1. This results in an isoform (5) that is shorter and has distinct N- and C-termini, compared to isoform 1.
