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.176C>T (p.P59L) alteration is located in exon 2 (coding exon 2) of the INO80B gene. This alteration results from a C to T substitution at nucleotide position 176, causing the proline (P) at amino acid position 59 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
