Genes affected

RBBP6 (HGNC:9889): (RB binding protein 6, ubiquitin ligase) The retinoblastoma tumor suppressor (pRB) protein binds with many other proteins. In various human cancers, pRB suppresses cellular proliferation and is inactivated. Cell cycle-dependent phosphorylation regulates the activity of pRB. This gene encodes a protein which binds to underphosphorylated but not phosphorylated pRB. Multiple alternatively spliced transcript variants that encode different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.1109T>C (p.M370T) alteration is located in exon 10 (coding exon 10) of the RBBP6 gene. This alteration results from a T to C substitution at nucleotide position 1109, causing the methionine (M) at amino acid position 370 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
