The razor clam, Sinonovacula constricta, is an important commercial bivalve and a popular mollusca food in China. Twelve polymorphic microsatellite markers were isolated from the razor clam using a partial genomic library enriched for tandem repeat sequences of (CA)16, (GA)16. Polymorphisms of these loci were evaluated in a wild population of 30 individuals. The allele number of these polymorphic markers ranged from 5-15 per locus with an average of 9.333. Observed and expected heterozygosity values ranged from 0.192-1.000 and 0.219-0.906. Polymorphism information content ranged from 0.209-0.892 with an average of 0.704. Three loci significantly deviated from Hardy-Weinberg equilibrium after Bonferroni correction. No significant linkage disequilibrium was detected between these loci. This set of microsatellite loci are useful for genetic studies in S. constricta.
缢蛏（Sinonovacula constricta）是一种重要的商业双壳贝类，也是中国受欢迎的软体动物食品。利用富含（CA）16、（GA）16串联重复序列的部分基因组文库，从缢蛏中分离出12个多态性微卫星标记。在30个个体的野生群体中评估了这些位点的多态性。这些多态性标记的等位基因数每个位点范围为5 - 15个，平均为9.333个。观察到的和预期的杂合度值范围分别为0.192 - 1.000和0.219 - 0.906。多态性信息含量范围为0.209 - 0.892，平均为0.704。经Bonferroni校正后，有3个位点显著偏离哈迪 - 温伯格平衡。在这些位点之间未检测到显著的连锁不平衡。这组微卫星位点可用于缢蛏的遗传学研究。
