Genes affected

ETV4 (HGNC:3493): (ETS variant transcription factor 4) Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of keratinocyte differentiation and positive regulation of transcription by RNA polymerase II. Located in chromosome and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

ETV4 links:

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

Feb 21, 2024

The c.885G>C (p.M295I) alteration is located in exon 9 (coding exon 8) of the ETV4 gene. This alteration results from a G to C substitution at nucleotide position 885, causing the methionine (M) at amino acid position 295 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
