NCIt definition : Human FOLR1 wild-type allele is located within 11q13.3-q14.1 and is approximately
7 kb in length. This allele, which encodes folate receptor alpha protein, is involved
in the trafficking of 5-methyltetrahydrofolate to the cell interior.;
NCIt note : FOLR1 gene is composed of 7 exons; exons 1 through 4 encode the 5' UTR and exons 4
through 7 encode the open reading frame. Due to the presence of 2 promoters, multiple
transcription start sites, and alternative splicing of exons, several transcript variants
are derived from this gene. These variants differ in the lengths of 5' and 3' UTR,
but they encode an identical amino acid sequence.;
