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.

See identical proteins and their annotated locations for NP_001029186.1

Status: PROVISIONAL

Description

Transcript Variant: This variant (MDEG1) uses an alternate 5' terminal exon compared to variant MDEG2. The resulting protein (isoform MDGEG1) is shorter and has a distinct N-terminus compared to isoform MDEG2.
