Genes affected

SLC7A3 (HGNC:11061): (solute carrier family 7 member 3) This gene encodes a member of the solute carrier family 7. The encoded protein is a sodium-independent cationic amino acid transporter. Alternate splicing results in multiple transcripts that encoded the same protein.[provided by RefSeq, May 2010]
