Gene Symbol IDH1
Synonyms HEL-216 | HEL-S-26 | IDCD | IDH | IDP | IDPC | PICD
Gene Description IDH1, isocitrate dehydrogenase (NADP(+)) 1, is an enzyme that catalyzes the conversion of isocitrate to alpha-ketoglutarate (alpha-KG) and is involved in the tricarboxylic acid cycle (PMID: 23999441, PMID: 28711227). Mutations in IDH1 are associated with aberrant conversion of alpha-KG to 2-HG, which is an oncogenic metabolite, and are recurrent in acute myeloid leukemia (PMID: 23999441) and glioma (PMID: 28711227, PMID: 32186930).

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.
