title: Magnetic resonance spectroscopy in a 9-day-old heterozygous female child with creatine transporter deficiency.
abstract: An X-linked creatine deficiency syndrome caused by mutations in the creatine transporter gene SLC6A8/CRTR mapped to Xq28 has recently been described. Essential in the recognition of this disorder is the absence of creatine on proton magnetic resonance spectroscopy (MRS) examination. A 9-day-old heterozygous female child with this syndrome demonstrated a significant reduction of creatine on proton MRS. She is a carrier of the R514X nonsense mutation.
