Genes affected
RXYLT1 (HGNC:13530): (ribitol xylosyltransferase 1) This gene encodes a type II transmembrane protein that is thought to have glycosyltransferase function. Mutations in this gene result in cobblestone lissencephaly. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]
RXYLT1-AS1 (HGNC:48910): (RXYLT1 antisense RNA 1)
