A non-human snp. The (C;C) genotype is linked to death for chickens However this snp is mostly useful as a way to notice where Promethease doesn't filter out non-human snps.
A;A
If you're seeing this in your Promethease report you have probably found a bug. Unless you are genotyping a chicken, in which case your chicken appears normal. Please report that you saw this message to info@snpedia.com .
A;C
If you're seeing this in your Promethease report you have probably found a bug. Unless you are genotyping a chicken, in which case your chicken appears to be a carrier for a rare allele. Please report that you saw this message to info@snpedia.com .
C;C
Please report that you saw this message to info@snpedia.com . If you're seeing this in your Promethease report you have probably found a bug. Unless you are genotyping a chicken, in which case your chicken appears to carry a rare and deadly mutation. If you are the chicken being genotyped ... you might want to sit down, I have some bad news.
