Genotype counts & sports games

In today's post, we'll just be doing some...simple counting with Genotype Counts (GC) at a Cambridge pub. ðŸ˜Ž The general form of  GC with a ref allele A and multiple alternative alleles (B,C,D, etc.) is: GC = AA, AB,BB, AC,BC,CC, AD,BD,CD,DD, ... GC fields basically capture the likelihood of two events occurring simultaneously at two spots. … Continue reading Genotype counts & sports games

gnomAD: expanding multi-allelic variants in VCF (Part 2)

VCF Playground - Level 2 Following my previous post on GC elements' order, I'm now going to present an empirical proof of this convention! As a reminder, the inferred order of elements within a GC field is: GC=AA, AB,BB, AC,BC,CC, AD,BD,CD,DD, AE,BE,CE,DE,EE, ... (1) Notation used: Reference Allele: A Alternative Alleles: B, C, D, ... (in order of appearance in the VCF … Continue reading gnomAD: expanding multi-allelic variants in VCF (Part 2)
