Genes affected

OASL (HGNC:8090): (2'-5'-oligoadenylate synthetase like) Enables DNA binding activity and double-stranded RNA binding activity. Involved in several processes, including interleukin-27-mediated signaling pathway; negative regulation of viral genome replication; and positive regulation of RIG-I signaling pathway. Located in cytosol; nucleolus; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.1360A>G (p.S454G) alteration is located in exon 6 (coding exon 6) of the OASL gene. This alteration results from a A to G substitution at nucleotide position 1360, causing the serine (S) at amino acid position 454 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
