Genes affected

DHX8 (HGNC:2749): (DEAH-box helicase 8) This gene is a member of the DEAH box polypeptide family. The encoded protein contains the DEAH (Asp-Glu-Ala-His) motif which is characteristic of all DEAH box proteins, and is thought to function as an ATP-dependent RNA helicase that regulates the release of spliced mRNAs from spliceosomes prior to their export from the nucleus. This protein may be required for the replication of human immunodeficiency virus type 1 (HIV-1). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]

Ambry Genetics

Apr 25, 2023

The c.211G>A (p.V71I) alteration is located in exon 2 (coding exon 2) of the DHX8 gene. This alteration results from a G to A substitution at nucleotide position 211, causing the valine (V) at amino acid position 71 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
