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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2023The c.937G>A (p.V313M) alteration is located in exon 5 (coding exon 5) of the OASL gene. This alteration results from a G to A substitution at nucleotide position 937, causing the valine (V) at amino acid position 313 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
