Relevance to Autism
This gene has been identified with syndromic autism, where a subpopulation of individuals with a given syndrome develop autism. As well, rare variants in the SLC6A8 gene have been identified with autism (Po-Argelles et al., 2006).
Molecular Function
The encoded protein has creatine:sodium symporter activity.
