Genes affected

SLC45A1 (HGNC:17939): (solute carrier family 45 member 1) This gene was isolated initially from a region on chromosome 1p that is frequently deleted in human neuroblastoma, although no causal relationship has since been demonstrated. The encoded protein belongs to the glycoside-pentoside-hexuronide cation symporter transporter family and may play a role in glucose uptake. [provided by RefSeq, Mar 2014]
