Genes affected

RBBP7 (HGNC:9890): (RB binding protein 7, chromatin remodeling factor) This protein is a ubiquitously expressed nuclear protein and belongs to a highly conserved subfamily of WD-repeat proteins. It is found among several proteins that binds directly to retinoblastoma protein, which regulates cell proliferation. The encoded protein is found in many histone deacetylase complexes, including mSin3 co-repressor complex. It is also present in protein complexes involved in chromatin assembly. This protein can interact with BRCA1 tumor-suppressor gene and may have a role in the regulation of cell proliferation and differentiation. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2010]

The c.1395G>C (p.E465D) alteration is located in exon 12 (coding exon 12) of the RBBP7 gene. This alteration results from a G to C substitution at nucleotide position 1395, causing the glutamic acid (E) at amino acid position 465 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
