This CCDS, which is supported by the mRNA DQ229900.1, represents a VEGFA isoform derived from an AUG start codon. Alternative translation initiation from multiple upstream non-AUG(CUG) codons is also possible for this gene, as indicated in PMIDs:11352659, 11563986 and 11731620. The longest isoform encoded by this variant, which is derived from the 5'-most CUG start codon, is represented by CCDS 55007.1.
