Human paternal population history was studied in 9 populations [three Native American, three Asian, two Caucasian and one African-derived sample(s)] using sequence and short tandem repeat haplotype diversity within the non-pseudoautosegmal region of the Y chromosome. Complete coding and additional flanking sequences (949 base pairs) of the RPS4Y locus were determined in 59 individuals from three of the populations, revealing a nucleotide diversity of 0.0147%, consistent with previous estimates from Y chromosome resequencing studies. One RPS4Y sequence variant, 711C > T, was polymorphic in Asian and Native American populations, but not in African and Caucasian population samples. The RPS4Y 711C > T variant, a second unique sequence variant at DYS287 and nine Y chromosome short tandem repeat (YSTR) loci were used to analyze the evolution of Y chromosome lineages. Three unambiguous lineages were defined in Asian, Native American and Jamaican populations using sequence variants at RPS4Y and DYS287. These lineages were independently supported by the haplotypes defined solely by YSTR alleles, demonstrating the haplotypes constructed from YSTRs can evaluate population diversity, admixture and phylogeny.
利用Y染色体非假常染色体区域内的序列和短串联重复单倍型多样性,对9个群体(三个美洲原住民群体、三个亚洲群体、两个高加索群体和一个非洲裔样本)的人类父系群体历史进行了研究。在来自其中三个群体的59名个体中,确定了RPS4Y基因座的完整编码序列和额外的侧翼序列(949个碱基对),核苷酸多样性为0.0147%,与之前Y染色体重测序研究的估计结果一致。一个RPS4Y序列变异,即711C>T,在亚洲和美洲原住民群体中具有多态性,但在非洲和高加索群体样本中没有。RPS4Y 711C>T变异、DYS287处的第二个独特序列变异以及九个Y染色体短串联重复序列(YSTR)位点被用于分析Y染色体谱系的进化。利用RPS4Y和DYS287处的序列变异,在亚洲、美洲原住民和牙买加群体中定义了三个明确的谱系。这些谱系得到了仅由YSTR等位基因定义的单倍型的独立支持,表明由YSTR构建的单倍型可以评估群体多样性、混合情况和系统发育。
