Sarah Leigh edited their review of gene: PTEN: Added comment: Based on the review from Zornitza Stark, this gene has been demoted to amber on this panel.; Changed rating: AMBER
Zornitza Stark changed review comment from: GI polyps and diverticula are a feature of Cowden syndrome. The link between variants in PTEN and monogenic IBD appears based largely on experimental/mouse model evidence. There is a series of 34 individuals with PTEN variants and a range of autoimmune phenotypes reported in 22266152, including colitis. Considering PTEN-related conditions are relatively common as are auto-immune disorders, I am not convinced this is enough for causality.; to: GI polyps and diverticula are a feature of Cowden syndrome.
