Based on LOVD v3 platform
• VCF file (genomic variants) loaded intoannotation tool, like Ensembl VEP• Maps variants to selected transcripts• Adds annotations
• LOVD+ pre-filters annotated VCF file and imports data• Analyze results using customizable analyses• Used in accredited diagnostic labs
NGS analysis using LOVD+

• Supports trio-analysis• Multi-sample VCF file or genotype of the parents in annotation• Complex family structures also possible, separate VCF files
• Pre-set inheritance based filtering• De novo, X-linked, recessive, imprinting
• Analysis of whole exome or using gene panels• Create gene panels with full history or define quick custom panels
• Link to third party software• e.g. Alamut, genome browsers, OMIM, LOVD search

Gene panel design
LOVD+
Simple forms for
gene panel design
NOTE: whether variants are linked to
a gene is defined during
variant annotation.
VEP uses a gene +/- 5000 bp.

Gene panel design
LOVD+
LOVD+ provides full
gene panel history
NOTE: whether variants are linked to
a gene is defined during
variant annotation.
VEP uses a gene +/- 5000 bp.

Variant coloring
LOVD+
Variants colored based on predicted effect• red = nonsense, frame shift, splicing• orange = missense, in-frame coding• green = silent, in UTR, intronic• blue = more than 1 predicted effect
