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.1568C>T (p.T523I) alteration is located in exon 7 (coding exon 6) of the MAVS gene. This alteration results from a C to T substitution at nucleotide position 1568, causing the threonine (T) at amino acid position 523 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
