Genes affected

CSPG4 (HGNC:2466): (chondroitin sulfate proteoglycan 4) A human melanoma-associated chondroitin sulfate proteoglycan plays a role in stabilizing cell-substratum interactions during early events of melanoma cell spreading on endothelial basement membranes. CSPG4 represents an integral membrane chondroitin sulfate proteoglycan expressed by human malignant melanoma cells. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 15, 2023

The c.5719G>A (p.V1907M) alteration is located in exon 10 (coding exon 10) of the CSPG4 gene. This alteration results from a G to A substitution at nucleotide position 5719, causing the valine (V) at amino acid position 1907 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
