Human knockout research: new horizons and opportunities.

Area of Science:

• Human genetics
• Genomics
• Mendelian genetics

Background:

• Mendelian genetics provides a robust dataset for understanding human gene function.
• Biallelic loss-of-function (LOF) mutations in autosomal recessive disorders represent natural human gene knockouts.
• These genetic variations offer unique insights into gene function in physiological and developmental contexts.

Purpose of the Study:

• To review the implications of studying human gene knockouts beyond disease states.
• To highlight the discovery of biallelic LOF mutations in healthy individuals.
• To discuss the role of these genetic variations in phenotypic diversity.

Main Methods:

• Review of existing literature on Mendelian genetics and human gene function.
• Analysis of genomic data to identify biallelic LOF mutations in human populations.
• Discussion of the physiological and developmental contexts of identified gene knockouts.

Main Results:

• Mendelian genetics offers compelling, medically actionable data on gene function.
• Biallelic LOF mutations are prevalent in Mendelian disorders and also found in healthy individuals.
• Human knockout research reveals a landscape of genetic variation impacting phenotypic diversity.

Conclusions:

• Studying human gene knockouts, particularly in healthy individuals, is crucial for understanding phenotypic diversity.
• Increased investment and multidisciplinary collaboration are needed to advance human knockout research.
• The potential benefits of human knockout research extend beyond disease causation, impacting our understanding of human biology.
