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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2023The c.1409T>C (p.V470A) alteration is located in exon 7 (coding exon 6) of the MAVS gene. This alteration results from a T to C substitution at nucleotide position 1409, causing the valine (V) at amino acid position 470 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
