Genes affected

SLC1A3 (HGNC:10941): (solute carrier family 1 member 3) This gene encodes a member of a member of a high affinity glutamate transporter family. This gene functions in the termination of excitatory neurotransmission in central nervous system. Mutations are associated with episodic ataxia, Type 6. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Feb 2014]

The c.398T>C (p.I133T) alteration is located in exon 4 (coding exon 3) of the SLC1A3 gene. This alteration results from a T to C substitution at nucleotide position 398, causing the isoleucine (I) at amino acid position 133 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
