Abstract

Here we provide an update of the 2013 report on the Nigerian Twin and Sibling Registry (NTSR). The major aim of the NTSR is to understand genetic and environmental influences and their interplay in psychological and mental health development in Nigerian children and adolescents. Africans have the highest twin birth rates among all human populations, and Nigeria is the most populous country in Africa. Due to its combination of large population and high twin birth rates, Nigeria has one of the largest twin populations in the world. In this article, we provide current updates on the NTSR samples recruited, recruitment procedures, zygosity assessment and findings emerging from the NTSR.

Funding

We would like to thank twins, siblings and mothers of twins who participated in the Nigerian Twin and Sibling Registry (NTSR) studies. Special thanks are given to the staff of Ministry of Education in Lagos State, research assistants, schoolteachers and principals for their contributions to the NTSR. The NTSR was funded mainly by the Pioneer Fund (USA) and Ulster Institute for Social Research (UK). Financial support for genotyping 100 mothers of opposite-sex dizygotic twins was provided as a gift from the Avera Institute for Human Genetics, USA.
