Most of the alternative splicing variations are categorized as alternative donor/acceptor splice sites or unspliced introns.
The variations are categorized as SNPs, insertions, divergent regions (based on lack of sequence identity) and tandem repeats.
This variation was categorized as 73 alternate SNP alleles, and 67 non-SNP alleles, including 51 insertions or deletions, 6 probable heterozygotes, and 10 null alleles.
Where a majority of the members (>75%), show <10% or >30% variation, they were categorized as "length-deviant" (64) and "length-rigid" (24) domain superfamilies (Tables 1 and 2).
The variations in CCR5 were categorized into haplotypes as described previously and were designated as CCR5 human haplogroups A (HHA), HHB, HHC, HHD, HHE, HHF*1, HHF*2, HHG*1, and HHG*2 [35].
The semiquantitative scoring by the investigators had a low observer variation; 92% of the specimens were categorized identically.
Variants that are greater than 1 repeat unit in length were categorized as multi-step variations.
Those not recorded in MitoMap database were categorized as novel mtDNA variations, and those appear in the database were categorized as reported polymorphisms or mutations.
The connectors in splice region were categorized in four batches with variations in sleeve length, bolts location, and number of bolts.
To estimate the variations of evolutionary rates resulting from vaccination, the HA sequences were categorized by sampling time.
