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]

Ambry Genetics

Aug 03, 2022

The c.305G>A (p.R102H) alteration is located in exon 4 (coding exon 3) of the MAVS gene. This alteration results from a G to A substitution at nucleotide position 305, causing the arginine (R) at amino acid position 102 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
