Compound het allele segregation in multi-generational pedigree with multiple affecteds #123
Comments
If it's not feasible to extend slivar to this compound-het functionality, I was thinking of running slivar twice, once on mother and her parents as a trio. And then take the mother's variants from the first run and merge with the children's variants and run slivar again on mother and her affected children. Thoughts? |
Hi Matt, |
Hey Brent,
Here's the pedigree I'm working with:
A mother (proband) with her parents and her 3 affected children
I did my usual slivar filtering and had TRPM4 compound het variants prioritized. But in checking the allele segregation and genotypes for all individuals it seems not all affecteds have both variants. UDN301487 lacks the chr19:49182889 variant. And UDN774226 lacks the chr19:49190460 variant.
Does compound-het only work on proband? Not all affecteds in the pedigree? Would it be easy to extend to all affecteds?
Thanks pal!
