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]
INO80B-WBP1 (HGNC:49199): (INO80B-WBP1 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring INO80B (INO80 complex subunit B) and WBP1 (WW domain-binding protein 1) genes on chromosome 2. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is unlikely to produce a protein product. [provided by RefSeq, Feb 2011]

The c.269T>C (p.V90A) alteration is located in exon 3 (coding exon 3) of the INO80B gene. This alteration results from a T to C substitution at nucleotide position 269, causing the valine (V) at amino acid position 90 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
