Genes affected

ZC3HAV1 (HGNC:23721): (zinc finger CCCH-type containing, antiviral 1) This gene encodes a CCCH-type zinc finger protein. This antiviral protein inhibits viral replication by recruiting cellular RNA degradation machineries to degrade viral mRNAs. The encoded protein plays an important role in the innate immune response against multiple DNA and RNA viruses, including Ebola virus, HIV and SARS-CoV-2 (which causes COVID-19).

The c.2053T>C (p.F685L) alteration is located in exon 9 (coding exon 9) of the ZC3HAV1 gene. This alteration results from a T to C substitution at nucleotide position 2053, causing the phenylalanine (F) at amino acid position 685 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
