Defective OGG1 Substrate Processing
Click the image above or here to open this pathway in the Pathway Browser
The majority of OGG1 mutants have been tested for their ability to excise 8-oxoguanine (8oxoG) from damaged DNA, while a small number of mutants have been tested for the ability to remove FapyG from DNA.
The following OGG1 mutants show at least a partial loss of their ability to remove 8oxoG:
OGG1 R46Q (Audebert, Chevillard et al. 2000; Audebert, Radicella et al. 2000);
OGG1 R154H (Audebert, Radicella et al. 2000, Bruner et al. 2000);
OGG1 R131Q (Chevillard et al. 1998, Bruner et al. 2000, Anderson and Dagget 2009);
OGG1 R229Q (Hyun et al. 2000, Hyun et al. 2002, Hill and Evans 2007);
OGG1 P266fs139* (Mao et al. 2007).
OGG1 R46L and OGG1 R131G have not been functionally studied but have been reported in cancer and predicted to be pathogenic. They are annotated as candidate disease variants based on their similarity with OGG1 R46Q and OGG1 R131Q, respectively.
OGG1 S326C, a frequent variant in European and Asian populations, is susceptible to oxidation, which diminishes catalytic activity under conditions of oxidative stress (Dherin et al. 1999, Yamane et al. 2004, Kershaw and Hodges 2012, Moritz et al. 2014).
The following OGG1 mutants show at least a partial loss of their ability to remove FapyG:
OGG1 R46Q (Audebert, Radicella et al. 2000);
OGG1 R154H (Audebert, Radicella et al. 2000).
OGG1 R46L has not been functionally studied but has been reported in cancer and predicted to be pathogenic. It is annotated as a candidate disease variant for FapyG excision, based on its similarity with OGG1 R46Q.
