Default Trio Structural variant genotyping

Hello,
I'm working with trio structural variant calling from Illumina paired-end WGS. I've called variants using LumpySV, and I have both bedpe and vcf files for mother, father, and child.

I now want to genotype these variants:
Both via heterozygous, homozygous, hemizygous, as well as based on inheritance patterns, i.e. Recessive, de novo

Then I want to take them through an annotation vs. genes, regulatory regions, DGV, etc.

If anyone has a pipeline set up for this or can point me to the correct place that would be very helpful.

Thanks,
Phil

Depending on the size of structural variants genotyping does not have a straightforward solution. Pindel can give you genotypes for smaller events (upto 100bp) but with larger events (> 1kb), even defining boundaries is a bit of a challenge, so as it is there is no out of the box solution. In the past I've used Bedtools to add gene annotation and roughly genotype the large SVs.
