结果:该研究对全球队列中HPDL相关的神经退行性疾病的自然历史进行了定量模拟,从而阐明了该疾病的分子和表型谱系,并鉴定出三个不同的患者亚组,其特征在于,以临床表型,发育轨迹和存活率的临床表型,临床表型,发育型和存活率的年龄差异显着差异。It also establishes genotype-phenotype associations, finding that presence of a predicted moderately pathogenic missense variant in at least one allele typically leads to a milder, predominantly spastic paraplegic phenotype (OR = 12.4, p < 0.0001) with later disease onset (11 years [IQR = 11] vs. 6 months [IQR = 11], p < 0.0001), whereas双重,高度致病的错义或蛋白质截断的变体与更严重的表型和预期寿命降低有关(中位生存期= 11.0岁)。
