Genes affected

SLC17A7 (HGNC:16704): (solute carrier family 17 member 7) The protein encoded by this gene is a vesicle-bound, sodium-dependent phosphate transporter that is specifically expressed in the neuron-rich regions of the brain. It is preferentially associated with the membranes of synaptic vesicles and functions in glutamate transport. The protein shares 82% identity with the differentiation-associated Na-dependent inorganic phosphate cotransporter and they appear to form a distinct class within the Na+/Pi cotransporter family.

The c.199A>G (p.I67V) alteration is located in exon 2 (coding exon 2) of the SLC17A7 gene. This alteration results from a A to G substitution at nucleotide position 199, causing the isoleucine (I) at amino acid position 67 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
