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.

W912R	missense	unknown	MSH6 W912R lies within the lever domain of the Msh6 protein (PMID: 17531815). W912R has not been characterized and therefore, its effect on Msh6 protein function is unknown (PubMed, May 2024).
Y1006*	nonsense	loss of function - predicted	MSH6 Y1006* results in a premature truncation of the Msh6 protein at amino acid 1006 of 1360 (UniProt.org). Y1006* has not been characterized, however, due to the loss of several functional domains including the ATPase domain (PMID: 17531815, PMID: 23391514), is predicted to lead to a loss of Msh6 protein function.
Y1006N	missense	loss of function - predicted	MSH6 Y1006N lies within the clamp domain of the Msh6 protein (PMID: 17531815). Y1006N (corresponds to Y1003N in mouse) results in impaired mismatch binding and deficient mismatch repair activity in in vitro assays (PMID: 31965077), and therefore, is predicted to lead to a loss of Msh6 protein function.
Y1044*	nonsense	loss of function - predicted	MSH6 Y1044* results in a premature truncation of the Msh6 protein at amino acid 1044 of 1360 (UniProt.org). Y1044* has not been characterized, however, due to loss of the ATPase domain (PMID: 17531815, PMID: 23391514), is predicted to lead to a loss of Msh6 protein function.
Y1066Wfs*21	frameshift	loss of function - predicted	MSH6 Y1066Wfs21 indicates a shift in the reading frame starting at amino acid 1066 and terminating 21 residues downstream causing a premature truncation of the 1360 amino acid Msh6 protein (UniProt.org). Y1066Wfs21 has not been characterized, however, due to loss of the ATPase domain (PMID: 17531815, PMID: 23391514), is predicted to lead to a loss of Msh6 protein function.
Y1256*	nonsense	unknown	MSH6 Y1256* results in a premature truncation of the Msh6 protein at amino acid 1256 of 1360 (UniProt.org). Y1256* has been identified in the scientific literature (PMID: 35739269, PMID: 33393477, PMID: 26552419), but has not been biochemically characterized and therefore, its effect on Msh6 protein function is unknown (PubMed, May 2024).
Y397fs	frameshift	loss of function - predicted	MSH6 Y397fs results in a change in the amino acid sequence of the Msh6 protein beginning at aa 397 of 1360, likely resulting in premature truncation of the functional protein (UniProt.org). Y397fs (reported as Y397fs*3) has not been biochemically characterized, but is associated with a loss of Msh6 protein expression and increased microsatellite instability in tumor samples (PMID: 14974087), and therefore, is predicted to lead to a loss of Msh6 protein function.
Y397H	missense	unknown	MSH6 Y397H lies within the mismatch binding domain of the Msh6 protein (PMID: 17531815). Y397H has not been characterized in the scientific literature and therefore, its effect on Msh6 protein function is unknown (PubMed, Apr 2024).
Y556F	missense	no effect - predicted	MSH6 Y556F lies within an MSH2-binding region of the Msh6 protein (PMID: 12019211). Y556F was not identified to interfere with Msh6 mismatch repair activity in a functional screen in mouse cells (PMID: 28531214), and did not demonstrate mismatch repair deficiency in an in vitro assay (PMID: 31965077), and therefore, is predicted to have no effect on Msh6 protein function.
Y850*	nonsense	loss of function - predicted	MSH6 Y850* results in a premature truncation of the Msh6 protein at amino acid 850 of 1360 (UniProt.org). Y850* has not been characterized, however, due to the loss of several functional domains including the ATPase domain (PMID: 17531815, PMID: 23391514), is predicted to lead to a loss of Msh6 protein function.
Y850C	missense	unknown	MSH6 Y850C lies within the lever domain of the Msh6 protein (PMID: 17531815). Y850C demonstrates proficient mismatch repair activity in an in vitro assay (PMID: 22102614), but has not been fully biochemically characterized and therefore, its effect on Msh6 protein function is unknown.
