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]

Apr 13, 2023

The c.1309T>G (p.F437V) alteration is located in exon 6 (coding exon 6) of the OASL gene. This alteration results from a T to G substitution at nucleotide position 1309, causing the phenylalanine (F) at amino acid position 437 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
