WebRead-based phasing is feasible using long reads such as those generated using single molecule sequencing technologies such as Pacific Biosciences ( Pendleton et al., 2015 ). Sequence reads that cover multiple variants provide partial haplotype information and can be assembled into longer haplotypes using computational methods ( Levy et al., 2007 ). WebSuch a strategy could start from RNAseq-based phasing, e.g. using phASER 30, yet it should be noted that state-of-the-art phASER-based allelic expression analyses typically still rely …
