It consists of collecting and keeping updated information about people born in multiple births who live in a specific geographical area or show specific characteristics.

Why a Twin Registry?

A Twin Register is essentially a scientific research tool. It consists of collecting and keeping updated information about people born in multiple births who live in a specific geographical area or show specific characteristics.

Its main objective is to serve as a source of information for carrying out research on the relative influence of genetic and environmental factors (diet, lifestyles…) on different matters of interest: health, physical characteristics, behaviour… In other words, it tries to explain why human beings are different one from another.

This kind of research compares the answers of twins depending on whether they are identical or non-identical. Since the former are genetically equal and the latter only share half of their genes, their comparison provides some valuable information. It is possible to analyse the relative importance of hereditary and environmental factors in the development of complex characteristics, like illnesses and disorders of all kinds. This is an important element in health research.
