Genes affected

SLC7A11 (HGNC:11059): (solute carrier family 7 member 11) This gene encodes a member of a heteromeric, sodium-independent, anionic amino acid transport system that is highly specific for cysteine and glutamate. In this system, designated Xc(-), the anionic form of cysteine is transported in exchange for glutamate. This protein has been identified as the predominant mediator of Kaposi sarcoma-associated herpesvirus fusion and entry permissiveness into cells. Also, increased expression of this gene in primary gliomas (compared to normal brain tissue) was associated with increased glutamate secretion via the XCT channels, resulting in neuronal cell death.

The c.1232G>A (p.R411Q) alteration is located in exon 10 (coding exon 10) of the SLC7A11 gene. This alteration results from a G to A substitution at nucleotide position 1232, causing the arginine (R) at amino acid position 411 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
