Task: Answer Verification
Input (English): Question: Is the high prevalence of autoantibodies to tissue transglutaminase in first-degree relatives of patients with type 1 diabetes associated with islet autoimmunity?
Answer: We found a high prevalence of celiac autoimmunity in patients and first-degree relatives of children with type 1 diabetes, but we found limited overlap between islet and celiac autoimmunity in nondiabetic relatives. The high prevalence of celiac autoimmunity may be explained by shared genetic susceptibility and identifies a population within which screening for the disease may be justified.
Output (English): no
