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]

Jan 23, 2024

The c.773C>T (p.S258F) alteration is located in exon 6 (coding exon 5) of the MAVS gene. This alteration results from a C to T substitution at nucleotide position 773, causing the serine (S) at amino acid position 258 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
