SLC6A20

Solute carrier family 6, member 20 also known as SLC6A20 is a protein which in humans is encoded by the "SLC6A20" gene.
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.
