ICAP
AC-11 - Smooth nuclear envelope
Previous Nomenclature Nuclear rim, nuclear envelope/membrane.
Description Homogeneous staining of the nucleus with greater intensity of the outer rim and no staining of the metaphase and anaphase chromatin. Accentuation of fluorescence at the points where adjacent cells touch each other may be observed.
Antigen Association Lamins A,B,C, or lamin-associated proteins.

About Clinical Relevance & List of Abbreviations
The AC-11 pattern is infrequently found in routine autoantibody testing and has been described in autoimmune-cytopenia, autoimmune liver diseases, linear scleroderma, anti-phospholipid syndrome, and systemic autoimmune rheumatic diseases; current information on clinical associations is based mainly on case reports and small cohorts [1-5]
Antigens recognized include lamins (A, B, C) and LAP-2; specific immunoassays for these autoantibodies are currently not commercially available [1-4]
