Rare single gene disorders: estimating baseline prevalence and outcomes worldwide

Area of Science:

• Genetics
• Pediatrics
• Public Health

Background:

• Non-communicable conditions, including genetic disorders, represent a growing proportion of child mortality and morbidity.
• Current public health programs primarily address common genetic disorders, overlooking the collective impact of rare single gene disorders.
• Rare single gene disorders impose a significant, often underestimated, public health burden on affected families.

Purpose of the Study:

• To develop an approach for estimating the collective frequency and health burden of rare single gene disorders up to age five.
• To provide population-level estimates for policy-makers and program planners in data-scarce settings.
• To aggregate rare single gene disorders into manageable groupings for better burden assessment.

Main Methods:

• Utilizing population-level demographic data.
• Employing assumptions derived from empirical data from settings with available information.
• Estimating the burden of rare single gene disorders in children up to five years of age.

Main Results:

• The study presents a novel approach to estimate the burden of rare single gene disorders.
• This method allows for the quantification of health impact in settings lacking empirical data.
• The findings are intended to inform public health policy and service planning.

Conclusions:

• Rare single gene disorders collectively represent a substantial public health concern.
• The proposed estimation approach can guide resource allocation and intervention strategies.
• Accurate burden estimation is crucial for addressing the needs of children affected by rare genetic conditions.
