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 GeneticsMar 31, 2024The c.865G>A (p.E289K) alteration is located in exon 4 (coding exon 4) of the OASL gene. This alteration results from a G to A substitution at nucleotide position 865, causing the glutamic acid (E) at amino acid position 289 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
