The Netherlands Twin Register (NTR) consists of individuals who have agreed to participate in twin-family studies and was established and is managed by the Department of Biological Psychology, VU University Amsterdam (see: https://tweelingenregister.vu.nl/). The NTR was established in 1987 and has enrolled around 120.000 twins and a roughly equal number of their relatives. The majority of twin families have participated one or more times in survey studies on a host of epidemiological variables including social demography, personality, lifestyle, somatic and mental health, and subsamples took part in biomaterial collection (e.g. DNA) and dedicated projects for e.g. neuropsychological, biomarker, and behavioral traits. The recruitment into the NTR is fully inclusive without any restrictions on enrolment. The NTR is committed to actively seek the commitment of its participants to science and their continued involvement in NTR research by maintaining a website, electronic newsletters, and the MijnNTR portal that provides personalized feedback to participants. The NTR resources, e.g. the longitudinal phenotyping, the extended pedigree structures, and the multi-generation genotyping allow for future twin-family research that will contribute to gene discovery, causality modelling, and studies of genetic and cultural inheritance of behavioral traits and mental and physical health. In the CID data catalogue, only the NTR projects for children and adolescents (<18 years of age) have been included. This is refered to as the Young Netherlands Twin Register (YNTR).

荷兰双生子登记库（Netherlands Twin Register, NTR）由同意参与双生子家庭研究的个体组成，由阿姆斯特丹自由大学生物心理学系建立并管理（详见：https://tweelingenregister.vu.nl/）。该登记库于1987年成立，目前已招募约12万名双生子及数量相近的亲属。多数双生子家庭参与过一次或多次针对一系列流行病学变量的调查研究，涵盖社会人口学、人格、生活方式、躯体与精神健康等领域；部分子样本参与了生物样本采集（如DNA）以及针对神经心理学、生物标志物、行为特征等的专项研究。该登记库的招募完全开放，无任何入组限制。荷兰双生子登记库致力于通过维护官方网站、发送电子通讯邮件，以及搭建为参与者提供个性化反馈的MijnNTR门户，积极争取参与者对科研事业的支持，并推动其持续参与登记库的相关研究。荷兰双生子登记库拥有多项研究资源，包括纵向表型评估、扩展家系结构、多代基因分型等，可支撑未来的双生子家庭研究，助力基因发现、因果建模，以及行为特征、精神与躯体健康的遗传和文化遗传相关研究。在CID数据目录中，仅纳入了针对儿童及青少年（年龄<18岁）的荷兰双生子登记库研究项目，该子库被称为青年荷兰双生子登记库（Young Netherlands Twin Register, YNTR）。
