Genes affected

INO80B (HGNC:13324): (INO80 complex subunit B) This gene encodes a subunit of an ATP-dependent chromatin remodeling complex, INO80, which plays a role in DNA and nucleosome-activated ATPase activity and ATP-dependent nucleosome sliding. Readthrough transcription of this gene into the neighboring downstream gene, which encodes WW domain-binding protein 1, generates a non-coding transcript. [provided by RefSeq, Feb 2011]

Ambry Genetics

Feb 10, 2022

The c.22G>A (p.G8R) alteration is located in exon 1 (coding exon 1) of the INO80B gene. This alteration results from a G to A substitution at nucleotide position 22, causing the glycine (G) at amino acid position 8 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
