Abstract

In the study reported, we prove that mutations in the SLC6A8 gene are responsible for SLC6A8 deficiency, a cerebral creatine deficiency syndrome (CCDS), since overexpression of the wild-type SLC6A8 open reading frame (ORF) restores the creatine uptake profile in SLC6A8-deficient fibroblasts.

摘要

在本报告的研究中,我们证明SLC6A8基因的突变是导致SLC6A8缺乏症(一种脑肌酸缺乏综合征,CCDS)的原因,因为野生型SLC6A8开放阅读框(ORF)的过表达可恢复SLC6A8缺陷型成纤维细胞中的肌酸摄取情况。
