Genes affected

OAS3 (HGNC:8088): (2'-5'-oligoadenylate synthetase 3) This gene encodes an enzyme included in the 2', 5' oligoadenylate synthase family. This enzyme is induced by interferons and catalyzes the 2', 5' oligomers of adenosine in order to bind and activate RNase L. This enzyme family plays a significant role in the inhibition of cellular protein synthesis and viral infection resistance. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 11, 2023

The c.124G>A (p.E42K) alteration is located in exon 1 (coding exon 1) of the OAS3 gene. This alteration results from a G to A substitution at nucleotide position 124, causing the glutamic acid (E) at amino acid position 42 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
