Genes affected

ASPSCR1 (HGNC:13825): (ASPSCR1 tether for SLC2A4, UBX domain containing) The protein encoded by this gene contains a UBX domain and interacts with glucose transporter type 4 (GLUT4). This protein is a tether, which sequesters the GLUT4 in intracellular vesicles in muscle and fat cells in the absence of insulin, and redistributes the GLUT4 to the plasma membrane within minutes of insulin stimulation. Translocation t(X;17)(p11;q25) of this gene with transcription factor TFE3 gene results in a ASPSCR1-TFE3 fusion protein in alveolar soft part sarcoma and in renal cell carcinomas. Multiple alternatively spliced transcript variants have been found. [provided by RefSeq, Oct 2011]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.278G>T (p.R93L) alteration is located in exon 4 (coding exon 4) of the ASPSCR1 gene. This alteration results from a G to T substitution at nucleotide position 278, causing the arginine (R) at amino acid position 93 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
