Gene symbol SLC6A8
Synonyms (NCBI Gene)
CCDS1CRTCRT-1CRT1CRTRCT1CTR5
Chromosome X
Chromosome location Xq28
Summary 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
