Fig. 1From: A novel SLC6A8 mutation associated with intellectual disabilities in a Chinese family exhibiting creatine transporter deficiency: case reportMolecular genetic tests and neurochemical analysis results in the index patient. a. Family tree of the proband and Sanger sequencing results in this study. Sanger sequencing validated the mutation, c.1181C > A (p.Thr394Lys), in the SLC6A8 gene in family members as I:1 wildtype, I:2 heterozygous carrier, II:1 hemizygous, II:2 hemizygous and II:3 wildtype. b. Proton magnetic resonance spectroscopy (MRS), examination using a 3.0-T system on the brain showed marked reduction of the brain creatine peak (left part), and brain MRI showed a thin corpus callosum in the proband (right part)Back to article page
