Term | Definition |
---|---|
allowed | This molecular profile is not a requirement for the trial, but patients are allowed to have this molecular profile. This applies mainly to molecular profiles that are typically excluded from trials. |
diagnostic | This molecular profile is required by some/all of the patients in the trial as part of their diagnosis/histological subtype, is not covered by the relevant disease term, and is not a target of the therapy in the trial. |
excluded | All patients in the trial are excluded from having this molecular profile. This can be related to the therapy or diagnosis. |
partial | This term is obsolete, and refers to situations where the related molecular profile is either required or excluded from a subset of patients in the trial. |
partial - excluded | Some patients in the trial are excluded from having this molecular profile. This can be related to the therapy or diagnosis. |
partial - required | This molecular profile is required by a subset of patients in the trial, and is a target/rationale for the therapy. This would be applicable in situations where a profile is required for patients with a specific indication, or if a patient has to have one of several different profiles. |
required | The molecular profile is required by all patients in trial, and is a target/rationale for the therapy. |
Term | Definition |
---|---|
conflicting | Evidence from peer-reviewed published literature from one or more studies demonstrating conflicting evidence that a molecular profile is or is not sensitive to a specific monotherapy or combination therapy. |
decreased response | Evidence from peer-reviewed published literature demonstrating that treatment with a specific monotherapy or combination therapy results in a decreased response in the context of a specific molecular profile, as compared to another therapy or molecular profile. Decreased response can be used to indicate that a molecular profile is associated with a weaker response to a therapy, however, it may not be considered resistant. |
no benefit | Evidence from peer-reviewed published literature demonstrating that a specific monotherapy or combination therapy does not benefit a particular tumor type, or there is evidence demonstrating a gene variant or category of variant does not respond to a specific monotherapy or combination therapy. No benefit can in cases where a molecular profile is not sensitive to a therapy, however, this is not due to therapeutic resistance. No benefit can also be used in cases where the addition of a second agent to a therapy does not add benefit over single agent therapy. |
not applicable | Used with evidence types of emerging, diagnostic, prognostic and risk factor. This is also used in cases where evidence from peer-reviewed published literature demonstrates that a monotherapy or combination therapy is associated with response in a tumor type, but has not been connected to a specific molecular profile or category variant (with profile defined as Unknown unknown). |
not predictive | Evidence from peer-reviewed published literature from one or more studies demonstrating that a molecular profile does not confer sensitivity or resistance to a specific monotherapy or combination therapy. |
predicted - resistant | Evidence from peer-reviewed published literature demonstrating that a category of variant or pathway is resistant to a specific monotherapy or combination therapy. This is also appropriate if the evidence described suggests potential resistance, in the cases of evidence related to a single patient, or if the data cannot be accessed, as in a conference abstract. |
predicted - sensitive | Evidence from peer-reviewed published literature demonstrating that an unspecified variant or pathway is sensitive to a monotherapy or combination therapy. This is also used in cases where the evidence is described as preliminary or modest, the variant is weakly connected to a target, if the data are limited and/or are not supported by functional evidence, or if the data cannot be accessed, as in a conference abstract. |
resistant | Evidence from peer-reviewed published literature demonstrating and specifying that a molecular profile is resistant to a specific monotherapy or combination therapy. Resistant is used when a molecular profile does not respond to a therapy due to a biochemically supported resistance mechanism, and when resistance is explicitly demonstrated. |
sensitive | Evidence from peer-reviewed published literature demonstrating that a specific molecular profile is sensitive to a monotherapy or combination therapy. |
unknown | There is evidence for a therapy in the context of a specific molecular profile, however, the relationship between the efficacy of the therapy and molecular profile is not clear. |
Term | Definition |
---|---|
Actionable | Actionable evidence is clinical or preclinical data supporting a connection between a molecular profile and a drug response. The related response type may be related to sensitivity or resistance. |

There are a number of “category” variants that correspond to higher level, non-specific variant types. These are used when the data source does not provide more specificity on the variant.
Category variants are variants that can be considered a parent variant to a group of other variants. These are typically used when a type or group of variants is indicated, but the specific variant is not.
Term | Definition |
---|---|
(X)aa#X | Indicates that the variant results in the replacement of the amino acid at the specified position by another amino acid. The can be considered a category containing any variant resulting in an amino acid substitution at the specified position. An example would be ‘BRAF V600X’. |
act mut | Indicates that the variant results in a gain of protein function. This can be considered a category containing any variant that results in a gain of function. In some cases, such as with small GTPases, this may indicate that the variant results in a loss of intrinsic function, resulting in activation of downstream signaling. In these cases, this can be considered a category that contains loss of function and/or gain of function variants resulting in downstream pathway activation. |
class # | Indicates a category of variants with a similar mechanism for activation or inactivation of downstream signaling. This can also indicate a variant belonging to that category. |
exon # indel | Indicates an insertion (ins) or deletion (del) in the specified exon of the gene. This can be considered a category containing any variant resulting from an insertion or deletion in the specified exon. An example would be ‘FLT3 exon 14 ins’. |
exonX | Indicates a mutation in the specified exon. This can be considered a category containing any variant within the specified exon. |
fusion | Indicates a fusion of the gene, but the fusion partner is unspecified. This can be considered a category containing any fusion in which the specified gene is a partner. |
inact mut | Indicates that the variant results in a loss of protein function. This can be considered a category containing any variant that results in a loss of function. |
mutant | Indicates an unspecified mutation in the gene. This can be considered a category containing any missense, indel, nonsense, or frameshift variant in the gene. |
rearrange | Indicates an unspecified rearrangement of the gene. This can be considered a category containing rearrangement of the specified gene. |
Non-specific variants are variants that are not attributed to a specific change in the amino acid or genomic sequence, and are not considered categories.

---|---|
gain of function | There are at least 2 pieces of functional evidence from peer-reviewed published literature demonstrating that the gene alteration present results in increased INTRINSIC activity of the protein. |
gain of function - predicted | There is peer-reviewed published literature demonstrating that similar gene alterations, both in type and location, have been characterized as gain of function. This is also appropriate if there are limited functional data. |
loss of function | There are at least 2 pieces of functional evidence from peer-reviewed published literature demonstrating that the gene alteration present results in decreased INTRINSIC activity of the protein. |
loss of function - predicted | There is peer-reviewed published literature demonstrating that similar gene alterations, both in type and location, have been characterized as loss of function. This is also appropriate if a gene alteration has not been characterized, but all known functional domains or a key domain (i.e. protein kinase domain) are lost, or if there are limited functional data. |
no effect | There is peer-reviewed published literature with functional evidence demonstrating that the gene alteration present results in activity similar to that of wild-type and does not demonstrate tumorigenic attributes. |
no effect - predicted | There is peer-reviewed published literature with modest functional evidence demonstrating that the gene alteration present results in activity similar to that of wild-type and does not demonstrate tumorigenic attributes. |
unknown | There is no peer-reviewed published literature demonstrating the gene alteration present affects the intrinsic activity of the protein. This can also be used when there is conflicting evidence about protein function. |
