Gene Detail

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.

V899_E902del has been identified in the scientific literature (PMID: 35616103), but has not been biochemically characterized and therefore, its effect on Ret protein function is unknown (PubMed, Apr 2024).
V915_K916insVHR	insertion	unknown	RET V915_K916insVHR results in the insertion of three amino acids in the protein kinase domain of the Ret protein between amino acids 915 and 916 (UniProt.org). V915_K916insVHR has not been characterized in the scientific literature and therefore, its effect on Ret protein function is unknown (PubMed, Feb 2024).
W85*	nonsense	loss of function - predicted	RET W85* results in a premature truncation of the Ret protein at amino acid 85 of 1114 (UniProt.org). Due to the loss of all known functional domains (UniProt.org), W85* is predicted to lead to a loss of Ret protein function.
wild-type	none	no effect	Wild-type RET indicates that no mutation has been detected within the RET gene.
Y1062C	missense	loss of function - predicted	RET Y1062C lies within the cytoplasmic domain of the Ret protein (UniProt.org). Y1062C results in reduced phosphorylation of Ret and Erk in cell culture (PMID: 26395553), and therefore, is predicted to lead to a loss of function of Ret protein function.
Y1062F	missense	loss of function	RET Y1062F lies within the cytoplasmic domain of the Ret protein (UniProt.org). Y1062F results in reduced phosphorylation of Ret and Erk (PMID: 26395553), decreased binding to Frs2 and Shc in cell culture (PMID: 11360177), decreased binding to Pkca and reduced activation of Pkc (PMID: 12771945), Mapk7 (Bmk1) (PMID: 11237712), and Rap1 in cell culture (PMID: 17210721), decreased PI3K/Akt and Mapk signaling in the context of RET C634Y expression in cell culture (PMID: 11390647, PMID: 10919641), and reduced signaling of the Ras-Mapk pathway in a reporter assay (PMID: 32062451).
Y606C	missense	gain of function	RET Y606C lies within the extracellular domain of the Ret protein (UniProt.org). Y606C results in ligand independent dimerization and constitutive phosphorylation of Ret, increased Erk2 phosphorylation (PMID: 18248647, PMID: 36166639), and transformation in culture (PMID: 36166639).
Y791F	missense	gain of function	RET Y791F lies within the protein kinase domain of the Ret protein (UniProt.org). Y791F confers a gain of function on the Ret protein, resulting in ligand independent kinase activity and activation of Stat3 signaling through Src, Jak1, and Jak2-dependent pathways in cell culture (PMID: 15753368).
Y791X	missense	unknown	RET Y791X indicates any Ret missense mutation that results in replacement of the tyrosine (Y) at amino acid 791 by a different amino acid.
Y806C	missense	gain of function - predicted	RET Y806C lies within the protein kinase domain of the Ret protein (UniProt.org). Y806C is predicted to lead to a gain of Ret protein function as indicated by transformation of cultured cells (PMID: 10679286), and has also been demonstrated to occur as a secondary resistance mutation in conjunction with other RET mutations (PMID: 19029224).	Y
Y806E	missense	unknown	RET Y806E lies within the protein kinase domain of the Ret protein (UniProt.org). Y806E has been demonstrated to confer secondary drug resistance in the context of other RET activating mutations (PMID: 19029224), but has not been biochemically characterized and therefore, its effect on Ret protein function is unknown (PubMed, Feb 2024).	Y
Y806F	missense	unknown	RET Y806F lies within the protein kinase domain of the Ret protein (UniProt.org). Y806F results in reduced autophosphorylation and transforming activity in the context of a constitutively active form of RET (PMID: 14711813), but has not been individually characterized and therefore, its effect on Ret protein function is unknown (PubMed, Dec 2023).
Y806N	missense	unknown	RET Y806N lies within the protein kinase domain of the Ret protein (UniProt.org). Y806N has been demonstrated to confer drug resistance in the context of KIF5B-RET in culture (PMID: 29908090), but has not been biochemically characterized and therefore, its effect on Ret protein function is unknown (PubMed, Jan 2024).	Y
EML4 - RET	fusion	gain of function - predicted	EML4-RET results from the fusion of EML4 and RET (PMID: 33082208), which results in increased Erk phosphorylation in cultured cells (PMID: 33848463), and therefore, is predicted to lead to a gain of protein function. EML4-RET has been identified in lung cancer (PMID: 33082208, PMID: 31485557, PMID: 30487236).
