The strongest evidence for linkage in 147 families with late-onset PD was on chromosome 17 near the tau gene -- previously shown to be involved in other neurodegenerative diseases including frontotemporal dementia with parkinsonism and progressive supranuclear palsy.

147个患有迟发型帕金森氏症的家庭在遗传研究中被发现，该病与17号染色体上的tau基因有关联。以前tau基因被认为与其它的神经变性疾病有关，如伴有震颤麻痹的额颞型痴呆以及进行性核上性麻痹有关。

More directly, their offspring could hae a lower ploidy because of potential links between somatic and gametic chromosome loss.

2N gametes are the result of meiotic mutation during micro- and mega-sporogenesis that bear the sporophytic rather than the gametophytic chromosome number. This paper reviewed the genetic markers including the morphologic, cytological, isozymes and DNA markers, which have been employed in the generation, inheritance, heterozygosity and marker-assisted breeding of 2n gametes based on the frequency of large pollen grains, cytological analyses, unexpected occurrence of polyploidy progeny and the associations between parents and progenies.

文章综述了植物2n配子发生及其遗传标记研究现状，论述涉及有关形态学标记、细胞学标记、同工酶标记乃至DNA标记等遗传标记在2n配子研究中的应用，指出通过花粉形态观察、大小孢子母细胞减数分裂行为观察、杂种后代倍性鉴定以及亲子分子标记相关分析等，对2n配子发生、2n配子遗传类型与杂合性以及2n配子在育种实践中的有效性等进行研究。
