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 16, 2022The c.1591C>T (p.P531S) alteration is located in exon 12 (coding exon 12) of the SLC17A7 gene. This alteration results from a C to T substitution at nucleotide position 1591, causing the proline (P) at amino acid position 531 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
