Genes affected

SLC10A3 (HGNC:22979): (solute carrier family 10 member 3) This gene maps to a GC-rich region of the X chromosome and was identified by its proximity to a CpG island. It is thought to be a housekeeping gene. Alternative splicing results in multiple transcript variants encoding distinct isoforms.[provided by RefSeq, Dec 2008]

The c.488G>A (p.R163Q) alteration is located in exon 2 (coding exon 1) of the SLC10A3 gene. This alteration results from a G to A substitution at nucleotide position 488, causing the arginine (R) at amino acid position 163 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
