Genes affected

SLC17A9 (HGNC:16192): (solute carrier family 17 member 9) This gene encodes a member of a family of transmembrane proteins that are involved in the transport of small molecules. The encoded protein participates in the vesicular uptake, storage, and secretion of adenoside triphosphate (ATP) and other nucleotides. A mutation in this gene was found in individuals with autosomal dominant disseminated superficial actinic porokeratosis-8. Alternative splicing results in multiple transcript variants.

The c.455G>A (p.R152Q) alteration is located in exon 4 (coding exon 4) of the SLC17A9 gene. This alteration results from a G to A substitution at nucleotide position 455, causing the arginine (R) at amino acid position 152 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
