Genes affected

SLC6A17 (HGNC:31399): (solute carrier family 6 member 17) The protein encoded by this gene is a member of the SLC6 family of transporters, which are responsible for the presynaptic uptake of most neurotransmitters. The encoded vesicular transporter is selective for proline, glycine, leucine and alanine. In mouse, the strongest expression of this gene was in cortical and hippocampal tissues where expression increased during embryonic brain development and peaked postnatally. Defects in this gene cause a form of autosomal recessive intellectual disability. [provided by RefSeq, Jul 2017]

The c.208A>G (p.I70V) alteration is located in exon 2 (coding exon 1) of the SLC6A17 gene. This alteration results from a A to G substitution at nucleotide position 208, causing the isoleucine (I) at amino acid position 70 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
