Disinhibition-dementia-parkinsonism-amyotrophy complex (DDPAC) is defined by familial adult-onset behavioral disturbance, followed by frontal lobe dementia, parkinsonism, and amyotrophy in variable proportions. A genetic etiology of DDPAC was suspected because of the familial clustering in family Mo, despite their wide geographic distribution. We have mapped the DDPAC locus to a 12-cM (sex averaged) region between D17S800 and D17S787 on chromosome 17q21-22. The basis for the variability of the clinical findings and pathology in DDPAC is unknown but suggests that the DDPAC locus should be screened as a candidate locus in family studies of conditions with behavioral abnormalities and neurological degeneration.
去抑制-痴呆-帕金森综合征-肌萎缩复合体(DDPAC)的定义为家族性成人起病的行为障碍,随后出现不同比例的额叶痴呆、帕金森综合征和肌萎缩。尽管Mo家族成员分布在广泛的地理区域,但因其家族聚集性,怀疑DDPAC存在遗传病因。我们已将DDPAC基因座定位到17号染色体q21-22区域上D17S800和D17S787之间一个12厘摩(平均性别)的区域。DDPAC临床发现和病理变化的基础尚不清楚,但这表明在对有行为异常和神经退行性变的疾病进行家族研究时,应将DDPAC基因座作为候选基因座进行筛查。
