Variant 12-112938688-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_006187.4(OAS3):c.158G>A(p.Arg53Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,226 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R53W) has been classified as Uncertain significance.

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

Sep 21, 2023

The c.158G>A (p.R53Q) 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 158, causing the arginine (R) at amino acid position 53 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
