Function
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 is a member of the subgroup of transporter with unidentified substrates within the Na+ and Cl− coupled transporter family. This gene is expressed in kidney, and its alternative splicing generates 2 transcript variants.Clinical significance
Mutation in the SLC6A20 gene are associated with iminoglycinuria. One of a cluster of 6 genes ''(SLC6A20'', ''LZTFL1'', ''CCR9'', ''FYCO1'', ''CXCR6'' and ''XCR1'') on chromosome 3 at location 3p21.31 associated with a genetic susceptibility to COVID-19 respiratory failure.References
