Genes affected

INO80 (HGNC:26956): (INO80 complex ATPase subunit) This gene encodes a subunit of the chromatin remodeling complex, which is classified into subfamilies depending on sequence features apart from the conserved ATPase domain. This protein is the catalytic ATPase subunit of the INO80 chromatin remodeling complex, which is characterized by a DNA-binding domain. This protein is proposed to bind DNA and be recruited by the YY1 transcription factor to activate certain genes. Alternative splicing results in multiple transcript variants.

The c.4661G>A (p.G1554E) alteration is located in exon 36 (coding exon 35) of the INO80 gene. This alteration results from a G to A substitution at nucleotide position 4661, causing the glycine (G) at amino acid position 1554 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
