NMPhenogen: a comprehensive database for genotype-phenotype correlation in neuromuscular genetic disorders

Area of Science:

• Genetics
• Neurology
• Bioinformatics

Background:

• Neuromuscular genetic disorders (NMGDs) are a diverse group of inherited diseases affecting peripheral nerves, motor neurons, neuromuscular junctions, or skeletal muscles.
• These disorders lead to progressive muscle weakness and degeneration, with varied clinical presentations complicating diagnosis.

Purpose of the Study:

• To develop a novel database, NMPhenogen, to enhance the diagnosis and understanding of NMGDs.
• To address challenges in correlating genotypic information with the wide phenotypic range of NMGDs and interpreting next-generation sequencing (NGS) variants.

Main Methods:

• NMPhenogen integrates NMGD-associated genes, variants, and clinical presentations into a centralized repository.
• It features two modules: NMPhenoscore for disease-phenotype correlation and a Variant Classifier for standardized variant classification based on ACMG guidelines.

Main Results:

• NMPhenogen provides a comprehensive resource for NMGD data, facilitating improved genotype-phenotype correlations.
• The database supports standardized variant classification, aiding in the interpretation of NGS findings.

Conclusions:

• NMPhenogen streamlines the diagnostic process for NMGDs.
• This resource aims to improve clinical decision-making, patient care, and genetic counseling for individuals with NMGDs.
