Manually add variants to a delivered case

When you:

• Complement NGS with other genetic tests done on the side (long-read sequencing, optical mapping, CGH, SNP array, karyotyping/FISH, repeat-primed PCR, MLPA, Southern blot, etc), or

• Choose to report a few adjacent variants as a single multi-nucleotide variant,

the need to add variants on top of the analysis results arises.

You can manually add variants absent from the VCF or not called from the FASTQ. Supported variant types are SNV, CNV, UPD, ROH, and STR. SV is coming soon!

To manually add a variant:

1. Click on the plus button on the top right of the Analysis tools tab.

1. In the Manually Add Variant window select variant type among SNV, CNV, UPD, ROH, and STR.

2. Fill in variant details according to the selected variant type:

SNV or ROH

CNV or UPD

STR

Manually added variant's Variant page

Unlike regular variants, the manually added variant's Variant page has a blue frame and a "Manually added variant" title.
