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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2023The c.626C>T (p.T209I) alteration is located in exon 5 (coding exon 5) of the SLC17A7 gene. This alteration results from a C to T substitution at nucleotide position 626, causing the threonine (T) at amino acid position 209 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
