Anti-centromere antibodies are found in approximately 60% of patients with limited systemic scleroderma and in 15% of those with the diffuse form of scleroderma. The specificity of this test is >98%. Thus, a positive anti-centromere antibody finding is strongly suggestive of limited systemic scleroderma.
Main antinuclear antibody patterns on immunofluorescence. [4] CREST syndrome typically displays the centromere pattern. CREST is not easily diagnosed as it closely mimics symptoms of other connective tissue and autoimmune diseases. Diagnoses are usually given when a patient presents two or more of the five major clinical symptoms. [5]

This is the highest dilution of the serum at which autoantibodies are still detectable. Positive autoantibody titres at a dilution equal to or greater than 1:160 are usually considered as clinically significant. Positive titres of less than 1:160 are present in up to 20% of the healthy population, especially the elderly.
Centromere repositioning and the formation of evolutionary new centromeres has been suggested to be a mechanism of speciation. [39] Centromere proteins are also the autoantigenic target for some anti-nuclear antibodies, such as anti-centromere antibodies.
Surprisingly, this gap exists around the country in part because doctors fear more false-positive breast cancer screenings. More screening may include false positives, Pushkin acknowledges, adding ...
The court documents noted that “the parents report a generally positive co-parenting relationship and will continue to communicate with one another by text messages and phone conversations.”
Anti Scl-70 antibodies (also called anti-topoisomerase I after the type I topoisomerase target [1]) is a type of antinuclear autoantibody seen mainly in diffuse systemic scleroderma, but is also seen the more limited form of systemic scleroderma called CREST syndrome. [2]
