About SLC6A20

Cytogenetic location: 3p21.31 Genomic coordinates (GRCh38): 3:45,755,449-45,796,536 (from NCBI)

This gene has 8 transcripts (splice variants), 209 orthologues, 19 paralogues and is associated with 3 phenotypes. Biased expression in duodenum (RPKM 11.0), small intestine (RPKM 8.2) and 4 other tissues.

Summary

Transport of small hydrophilic substances across cell membranes is mediated by substrate-specific transporter proteins which have been classified into several families of related genes. The protein encoded by this gene belongs to the sodium:neurotransmitter symporter (SNF) family and functions as a proline transporter expressed in kidney and small intestine. Mutations in this gene are associated with Hyperglycinuria and Iminoglycinuria. [provided by RefSeq, Jul 2020]
