本研究报告了使用连锁分析对涉及双相情感障碍的风险基因进行的全基因组扫描,其中包含 613 个微卫星标记,包括对有前景区域的额外测试。正如之前发表的,在染色体 12q24.3 处获得了显着连锁,D12S1639 的两点参数 lod 得分为 3.42,包括两个家族的所有成员(经验 P 值 0.00004,全基因组 P 值 0.0417)。 D12S1639 的多点参数 Lod 评分为 3.63(全基因组 P 值 0.0265)。在染色体 1p22-p21 上,在标记 DIS216 上发现了仅受影响的参数化两点 lod 得分 2.75(经验 P 值 0.0002,全基因组 P 值 0.1622)。 WS216 的三点基因座得分为 2.98(全基因组 P 值 0.1022),WS216 的最大 NPL-all 得分为 17.60(P 值 0.00079)的多点非参数分析进一步支持了这一发现。染色体 4p16、6q14-q22、10q26 和 16p13.3 上的许多其他基因座产生的参数基因座得分约为或高于 2。
The present study reports a genomewide scan using linkage analysis for risk genes involved in bipolar disorder with 613 microsatellite markers including additional testing of promising regions. As previously published significant linkage was obtained at chromosome 12q24.3 with a two-point parametric lod score of 3.42 at D12S1639 including all members in both families (empirical P-value 0.00004, genome-wide P-value 0.0417). The multipoint parametric lod score at D12S1639 was 3.63 (genome-wide P-value 0.0265). At chromosome 1p22-p21 a parametric, affecteds-only two-point lod score of 2.75 at marker DIS216 was found (empirical P-value 0.0002, genome-wide P-value 0.1622). A three-point loci score of 2.98 (genome-wide P-value 0.1022) at WS216, and a multipoint non-parametric analysis with a maximum NPL-all score of 17.60 (P-value 0.00079) at WS216 further supported this finding. A number of additional loci on chromosomes 4p16, 6q14-q22, 10q26 and 16p13.3 yielded parametric loci scores around or above 2.
