Those were the statuses I was referring to Will.

 

Which leads me to ask - what were the statuses that Andrea listed?

Hello,

 

I think there are some crossed wires here - validation_status is a
property of a variation supplied to us by dbSNP.

 

Their descriptions are here:

 

http://www.ncbi.nlm.nih.gov/projects/SNP/snp_legend.cgi?legend=validatio
n

The pictures are, in order:

 

cluster

freq

submitter

doublehit

hapmap

1000Genome

I believe the validatation statuses are just pass and fail 

If you query the variation schema directly you can find the reasons for
failure when a variation is imported from say dbSNP

mysql> select description from failed_description;
+--------------------------------------------------------+
| description                                            |
+--------------------------------------------------------+
| Variation maps to more than 3 different locations      |
| None of the variant alleles match the reference allele |
| Variation has more than 3 different alleles            |
| Loci with no observed variant alleles in dbSNP         |
| Variation does not map to the genome                   |
| Variation has no associated sequence                   |
+--------------------------------------------------------+
6 rows in set (0.06 sec)

As will has said, they map all variants to the positive strand and make
sure at least one of the variant alleles exists at the base position in
the forward strand. If this failed you would get the error 'None of the
variant alleles match the reference allele.' I think the others are
fairly self explanatory though i'm not sure how a variant could have no
associated sequence if it was imported from dbSNP

Thanks Graham - 
 
Can you also tell me where to find information on the meaning of the
possible validation statuses?

Hi Gavin,
 
The alleles of a transcript variation always represent the genomic base
change.
 
Cheers,

	Hi,
	 
	When I pull transcript variation alleles via the API, does the
allele

shown (e.g. A/T) represent the genomic base change, or the
transcriptomic one?
