Genes affected

SLC49A4 (HGNC:16628): (solute carrier family 49 member 4) This gene encodes a membrane-bound protein from the major facilitator superfamily of transporters. Disruption of this gene by translocation has been associated with haplo-insufficiency and renal cell carcinomas. Alternatively spliced transcript variants have been described, but their biological validity has not yet been determined. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.484G>A (p.V162I) alteration is located in exon 3 (coding exon 3) of the DIRC2 gene. This alteration results from a G to A substitution at nucleotide position 484, causing the valine (V) at amino acid position 162 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
