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 15, 2023

The c.517G>A (p.E173K) alteration is located in exon 4 (coding exon 4) of the INO80B gene. This alteration results from a G to A substitution at nucleotide position 517, causing the glutamic acid (E) at amino acid position 173 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
