The Colorado Twin Registry: 2019 Update

Area of Science:

• Twin studies
• Population genetics
• Longitudinal research

Background:

• The Colorado Twin Registry (CTR) is a population-based resource established using birth and school records.
• Previous reports detailed CTR developments through 2012.
• The registry facilitates research on twins born from 1968 to the present.

Purpose of the Study:

• To update on the CTR's developments since 2012.
• To describe new twin samples and associated studies.
• To detail genotyping efforts and collaborations involving CTR participants.

Main Methods:

• Summarizing historical ascertainment and recruitment data.
• Describing updates for four existing twin samples.
• Introducing two new twin samples and their studies.
• Reviewing genotyping history and consortia involvement.

Main Results:

• The CTR has expanded its sample size and research scope since 2012.
• Two new twin samples and their complementary studies have been established.
• Genotyping initiatives and collaborative research have increased.
• The CTR continues to be an active resource for twin research.

Conclusions:

• The Colorado Twin Registry remains a vital and expanding resource for twin research.
• The registry supports both ongoing longitudinal studies and new research opportunities.
• Continued development enhances the CTR's utility for genetic and population-based research.
