Genes affected

BCAN (HGNC:23059): (brevican) This gene encodes a member of the lectican family of chondroitin sulfate proteoglycans that is specifically expressed in the central nervous system. This protein is developmentally regulated and may function in the formation of the brain extracellular matrix. This protein is highly expressed in gliomas and may promote the growth and cell motility of brain tumor cells. Alternate splicing results in multiple transcript variants.

The c.1151C>G (p.T384R) alteration is located in exon 7 (coding exon 6) of the BCAN gene. This alteration results from a C to G substitution at nucleotide position 1151, causing the threonine (T) at amino acid position 384 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
