Gene BRAF
Variant class 2
Impact List unknown

Gene Variant Descriptions BRAF Class 2 variants are BRAF variants that activate BRAF and downstream signaling in a dimer-dependent, RAS-independent manner (PMID: 28783719, PMID: 26343582).
Associated Drug Resistance
Category Variants Paths

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.

BRAF class 2 pancreatic cancer predicted - sensitive Exarafenib Preclinical - Cell culture Actionable In a preclinical study, Exarafenib (KIN-2787) treatment led to inhibition of tumor growth in a pancreatic cell line xenograft model harboring a BRAF class 2 mutation (J of Clin Oncol 39, no. 15_suppl (May 20, 2021) 3116-3116). detail...
BRAF class 2 colorectal cancer decreased response Cetuximab Clinical Study Actionable In a clinical study, colorectal cancer patients harboring class 2 BRAF mutations demonstrated a decreased response to treatment with the combination of either Erbitux (cetuximab) or Vectibix (panitumumab) plus chemotherapy compared to those with class 3 BRAF mutations, with a response rate of 8% (1/12) vs 50% (14/28) (P=0.02), respectively, in first, second, third or later-line setting and a response rate of 17% (1/6) vs 78% (7/9) (P=0.04), respectively, in the first or second-line setting (PMID: 31515458). 31515458

BRAF class 2 Advanced Solid Tumor predicted - sensitive Exarafenib Case Reports/Case Series Actionable In a Phase I trial, Exarafenib (KIN-2787) was tolerated and resulted in a partial response in 17.6% (6/34) and stable disease in 23.5% (8/34) of patients with BRAF-driven advanced solid tumors or NRAS-driven melanoma, including a partial response in 1 patient harboring a BRAF class 2 mutation (Cancer Res (2023) 83 (8_Supplement): CT032; NCT04913285). detail...
