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 (4) differs in the 5' UTR and uses an alternate splice donor, which results in the use of an alternate start codon and a frameshift in the 5' coding region compared to variant 1. The encoded isoform (2) has a distinct N-terminus and is shorter than isoform 1.
