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.689T>C (p.L230P) alteration is located in exon 6 (coding exon 5) of the MAVS gene. This alteration results from a T to C substitution at nucleotide position 689, causing the leucine (L) at amino acid position 230 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
