Genes affected

MX1 (HGNC:7532): (MX dynamin like GTPase 1) This gene encodes a guanosine triphosphate (GTP)-metabolizing protein that participates in the cellular antiviral response. The encoded protein is induced by type I and type II interferons and antagonizes the replication process of several different RNA and DNA viruses. There is a related gene located adjacent to this gene on chromosome 21, and there are multiple pseudogenes located in a cluster on chromosome 4. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

Ambry Genetics

Apr 12, 2022

The c.131A>G (p.Q44R) alteration is located in exon 8 (coding exon 2) of the MX1 gene. This alteration results from a A to G substitution at nucleotide position 131, causing the glutamine (Q) at amino acid position 44 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
