adpenetrance

adpenetrance estimates the penetrance of genetic variants associated with autosomal dominant traits to quantify the probability that carriers express the phenotype for genetic risk assessment and research.

Key Features:

• Population-scale data utilization: Leverages population-scale data to estimate penetrance, enabling robust analysis when large family pedigrees are unavailable and for rare, late-onset, or complex diseases.
• Case-control and affected-only inputs: Employs a method that uses data from both affected (cases) and unaffected (controls) individuals and can operate using affected-only samples by incorporating family disease history.
• Validation and consistency: Validated through simulation studies and produces estimates consistent with existing knowledge and established methods.
• Bias resilience: Circumvents limitations of kinship-specific penetrance estimates and reduces ascertainment biases to provide more generalized penetrance estimates for autosomal dominant traits.

Scientific Applications:

• Genetic Counseling: Provides penetrance-based risk assessments to inform counseling for individuals and families carrying pathogenic variants.
• Disease Research: Enhances understanding of the genetic basis of diseases by quantifying variant-specific penetrance for research studies.
• Gene Therapy: Informs evaluation of potential therapeutic interventions by providing penetrance estimates for target variants.

Methodology:

Analyzes population-scale case-control data, can incorporate family disease history for affected-only samples, and uses simulation studies for validation while addressing kinship-specific limitations and ascertainment biases.
