TranscriptVariant:
This variant (5) differs in the 5' UTR, lacks a portion of the 5' coding region, uses a downstream in-frame start codon, and uses an alternate splice site that results in a frameshift in the 3' coding region, compared to variant 1. The encoded isoform (4) is shorter at the N-terminus and has a distinct C-terminus, compared to isoform 1.
