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]

Feb 24, 2022

The c.1067C>G (p.A356G) alteration is located in exon 6 (coding exon 5) of the MAVS gene. This alteration results from a C to G substitution at nucleotide position 1067, causing the alanine (A) at amino acid position 356 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
