Maximum likelihood scores (MLS) in candidate regions 5q, 11q, and CD28/CTLA4 on 2q33 in the entire study group of 102 families and in the subgroups. Group ALL (all 102 families) was divided into group DH (dermatitis herpetiformis) and group CD (absence of dermatitis herpetiformis) (A-C) or group FM (male patients among affected siblings) and group FF (absence of male patients among affected siblings) (D-F). Marker positions are shown as triangles, from left to right: at 5q, D5S410, D5S422, D5S2032, D5S425, D5S2069, and D5S2111; at 11q, D11S898, D11S4111, D11S4142, D11S976, D11S4171, CD3D, D11S934, and D11S910; and at 2q33, D2S2392, D2S116, D2S2214, CTLA4(AT)n, D2S2189, and D2S2237.
