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.

Description

Transcript Variant: This variant (2) lacks an alternate exon in the 3' coding region resulting in a frameshift compared to variant 1. The encoded isoform (2) has a shorter and distinct C-terminus compared to isoform 1. Variants 2 and 4 encode the same isoform.

NR_144388.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (5) uses a different splice site in an internal exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
