Genes affected

MAVS (HGNC:29233): (mitochondrial antiviral signaling protein) This gene encodes an intermediary protein necessary in the virus-triggered beta interferon signaling pathways. It is required for activation of transcription factors which regulate expression of beta interferon and contributes to antiviral innate immunity. [provided by RefSeq, Jul 2020]

The c.1301G>T (p.G434V) alteration is located in exon 7 (coding exon 6) of the MAVS gene. This alteration results from a G to T substitution at nucleotide position 1301, causing the glycine (G) at amino acid position 434 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
