Gene Symbol RB1
Synonyms OSRC | p105-Rb | p110-RB1 | pp110 | PPP1R130 | pRb | RB
Gene Description RB1, retinoblastoma-associated protein, is a key negative regulator of the G1 to S transition during cell division (PMID: 15084261) and also plays a role in cell differentiation, survival, senescence, epigenetic regulation, and genome stability (PMID: 21295686, PMID: 23359405, PMID: 22293180). Inactivation of Rb1 and loss of Rb1 tumor suppressor function has been identified in many early stage cancers (PMID: 26160835).
ACMG Incidental List v2.0:
Yes, Retinoblastoma (PMID: 27854360)


  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"


  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

Variant Impact Protein Effect Variant Description Associated with drug Resistance
inact mut unknown loss of function RB1 inact mut indicates that this variant results in a loss of function of the Rb1 protein. However, the specific amino acid change has not been identified.
mutant unknown unknown RB1 mutant indicates an unspecified mutation in the RB1 gene.
