HighlightsThe solute family 19, member 1, is a protein which in humans is encoded by the SLC19A1 gene. It is also named as SLC19A1, Intestinal folate carrier 1(IFC-1), Placental folate transporter or Reduced folate carrier protein (RFC). It is a transporter for folate intake. Folate uptake in human placental chorion cells is produced by a new mechanism called potocytosis. The potocytosis consists of three functional components, the folate receptor, the folate transporter, and the v-type H+-pump. Transport of folate compounds into mammalian cells can be mediated by receptors (see folate receptor 1) or vector-mediated mechanisms. Functional coordination between these two mechanisms is considered to be a method of folate uptake in certain cell types.

SLC19A1 plays a role in maintaining the intracellular concentration of folic acid. People with a specific polymorphism of SLC19A1 (c.80 GG) have lower levels of folate. Methotrexate (MTX) is an anti-folate chemotherapeutic drug that is actively transported by a carrier-mediated absorption system. Other studies have also shown that people who carry c.80AA Polymorphic polymorphisms treated with methotrexate have higher levels of anti-folate chemotherapy drugs. Therefore, depending on the patient's genotype, a personalized dose of the drug may be necessary.

These results suggest that SLC19A1 SNP and haplotype analysis can provide personalized HD-MTX treatment for children with ALL /NHML for better therapeutic results.
The authors believe that damage to the function of the NFKBIE gene can reduce the uptake of cells by MTX, suggesting that this gene is an important factor in the outcome of RA.
This article reveals that cognition of adults is involved in MTHFR, SLC19A1 gene polymorphism and serum Hcy levels.
Although these findings support the role of the SLC19A1 gene in the etiology of ASD, it is not an important risk factor for ASD samples analyzed in this study.
These results indicate that hypermethylation of the PCDH-γ-A12 and SLC19A1 promoters perhaps lead to the occurrence and metastasis of colorectal cancer in the Chinese Han population.
