We have noted a substantial increase the proportion of non-biallelic SNPs across dbSNP 144 and 155 (increased from ~1% to 24%). This is explained in detail here and summarised in the code below (fuicntion written by @hpages).
Note that this is based on the dbSNP versions in Bioconductor (SNPlocs.Hsapiens.dbSNP) so we would like to confirm this aligns with dbSNP versions outside of Biocnductor but there doesn't seem to be any numbers available online about it. The only piece of work about this is quite old now and doesn't give specific numbers SNPs that come in threes. It would be great if anyone has any insight on this.
