NCBI's alignment of the flanking sequences had at least one mismatch or gap. (UCSC's re-alignment of flanking sequences to the genome may be informative -- see below.)3************************************************************
There are other rsIds at this position with identical variation.1********************
Allele frequency is given for only one allele and is 100%. A frequent cause, when chromosome counts are small, is that chromosome counts were submitted only for a homozygous non-reference variant from a personal genome.1********************
There are other rsIds at this position with different variation.1********************
Allele frequencies are given for alleles that do not match the reported observed alleles.1********************
A deletion (from the genome) was observed but the annotation spans 0 bases. (UCSC's re-alignment of flanking sequences to the genome may be informative -- see below.)1********************
An insertion (into the genome) was observed but the annotation spans more than 0 bases. (UCSC's re-alignment of flanking sequences to the genome may be informative -- see below.)1********************
All observed alleles are single-base, but the annotation spans more than 1 base. (UCSC's re-alignment of flanking sequences to the genome may be informative -- see below.)1********************
All observed alleles are single-base, but the annotation spans 0 bases. (UCSC's re-alignment of flanking sequences to the genome may be informative -- see below.)1********************
This single-base substitution is tri-allelic.1********************
This single-base substitution is quad-allelic.1********************
Observed allele(s) from dbSNP have unexpected format for the given class.1********************
Observed allele not given (length too long).1********************
Observed allele(s) from dbSNP contain IUPAC ambiguous bases.1********************
UCSC reference allele does not match any observed allele from dbSNP.1********************
This variant aligns in more than one location.1********************
The reference allele from dbSNP does not match the UCSC reference allele.1********************
At least one allele frequency corresponds to a non-integer (+-0.010000) count of chromosomes on which the allele was observed. The reported total sample count for this SNP is probably incorrect.1********************
The reference allele from dbSNP matches the reverse complement of the UCSC reference allele.1********************
Allele frequencies do not sum to 1.0 (+-0.010000). This SNP's allele frequency data are probably incomplete.1********************
