RISCALW

RISCALW calculates genetic risk for Duchenne muscular dystrophy (DMD) in families using an extended inheritance model that incorporates germline mosaicism and sex- and mutation type-specific new mutation rates. It performs pedigree-based risk estimation tailored to arbitrary family structures.

Key Features:

• Extended DMD Genetic Model: Incorporates germline mosaicism and variable mutation rates by sex and mutation type for risk computation.
• Flexible Pedigree Input: Supports arbitrary family structures for customized genetic risk analysis.
• Diagnostic Data Integration: Utilizes genotypes from intragenic and flanking dystrophin gene markers, creatine kinase levels, and female deletion test results.
• Model Assumption Evaluation: Assesses impact of mutation rate differences and other parameters on calculated risk.

Scientific Applications:

• Genetic Counseling in Duchenne Muscular Dystrophy: Provides quantitative carrier and recurrence risk estimates for families affected by DMD.

Methodology:

RISCALW applies a pedigree-based probabilistic model of DMD inheritance that integrates germline mosaicism and sex-dependent mutation rates, combining molecular marker data and clinical measurements to compute individual genetic risk probabilities.
