Primary immunodeficiency or monogenic inflammatory bowel disease v9.54 CD48 Achchuthan Shanmugasundram Classified gene: CD48 as Amber List (moderate evidence)
Primary immunodeficiency or monogenic inflammatory bowel disease v9.54 CD48 Achchuthan Shanmugasundram Added comment: Comment on list classification: There are two unrelated patients with two different variants affecting the same residue and functional evidence available in support of the association of CD48 gene with immune dysregulation. Hence, this gene can be promoted to green rating in the next GMS update.
Primary immunodeficiency or monogenic inflammatory bowel disease v9.54 CD48 Achchuthan Shanmugasundram Gene: cd48 has been classified as Amber List (Moderate Evidence).
