Genetic Variant INO80B:p.Gly29Ala (chr2-74455433-G-C) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_031288.4(INO80B):c.86G>C(p.Gly29Ala) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,844 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G29D) has been classified as Uncertain significance.

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 links:

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]
