Summaries for SLC6A8 Gene

Entrez Gene Summary for SLC6A8 Gene

  • The protein encoded by this gene is a plasma membrane protein whose function is to transport creatine into and out of cells. Defects in this gene can result in X-linked creatine deficiency syndrome. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]

GeneCards Summary for SLC6A8 Gene
