Ribitol-5-phosphate xylosyltransferase is an enzyme encoded by RXYLT1 gene.^[4]

Gene

RXYLT1 is located on the long arm (q) of chromosome 12 on position 14.2, from base pair 63,779,833 to base pair 63,809,792.^[5]^[6]

This enzyme is located in the golgi apparatus, and serves as a ribitol b1,4-xylosyltransferase for dystroglycan.^[7]
