Abstract Text The application of pan-cancer next-generation sequencing panels in the clinical setting has facilitated the identification of low frequency somatic mutations and the testing of new therapies in solid tumors using the "basket trial" scheme. However, little consideration has been given to the relevance of nonsynonymous germline variants, which are likely to be uncovered in tumors and germline and which may be relevant to prognostication and prediction of treatment response.We analyzed matched tumor and normal DNA from 34 melanoma patients using an Ion Torrent cancer-associated gene panel. We elected to study the germline variant Q472H in the kinase insert domain receptor (KDR), which was identified in 35% of melanoma patients in both a pilot and an independent 1,223 patient cohort. Using patient-derived melanoma cell lines and human samples, we assessed proliferation, invasion, VEGF levels, and angiogenesis by analyzing tumor microvessel density (MVD) using anti-CD34 antibody.Serum VEGF levels and tumor MVD were significantly higher in Q472H versus KDR wild-type (WD) patients. Primary cultures derived from melanomas harboring the KDR variant were more proliferative and invasive than KDR wild type. Finally, using a VEGFR2 antibody, we showed that KDR Q472H cells were sensitive to targeted inhibition of VEGFR2, an effect that was not observed in KDR WT cells.Our data support the integration of germline analysis into personalized treatment decision-making and suggest that patients with germline KDR variant might benefit from antiangiogenesis treatment.

Filtering

  • 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"

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.

KDR Q472H missense gain of function KDR (VEGFR2) Q472H does not lie within any known functional domains of the Kdr (Vegfr2) protein (UniProt.org). Q472H confers a gain of function to the Kdr (Vegfr2) protein, resulting in increased phosphorylation of Kdr (Vegfr2) in cell culture, increased serum VEGF levels, and increased microvessel density in tumor samples (PMID: 21712447, PMID: 26631613).

KDR Q472H melanoma sensitive unspecified VEGFR2 antibody Preclinical Actionable In a preclinical study, human melanoma cells harboring KDR (VEGFR2) Q472H demonstrated increased sensitivity to treatment with a VEGFR2 (KDR) function-blocking antibody compared to cells with wild-type KDR (VEGFR), resulting in decreased proliferation and invasion in culture (PMID: 26631613). 26631613
