Gene Symbol TSC1
Synonyms LAM | TSC
Gene Description TSC1, TSC complex subunit 1, is a tumor suppressor (PMID: 30562755) that forms a complex with Tsc2 and inhibits mTOR pathway signaling, thus regulating cell growth and metabolism (PMID: 27226234). Germline TSC1 inactivating mutations cause tuberous sclerosis complex and somatic TSC1 mutations have been identified in various cancers, including renal cell carcinoma, mucosal melanoma, and breast cancer (PMID: 27226234, PMID: 30327302, PMID: 29185092, PMID: 28027327).

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

  • 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.
