Gene Position c.

Hello! I have some problem with SNP. So, I have information about localization this SNP on chromosome: 11:g.103301489C>A. c.-215C>A I understand that this is the 11 Chr and 103301489 nucleotide but I don`t understand what means c.-215C>A. If you have some information or manual about it, I will be so happy if you give me this information!!!

The coding reference sequence identifier is missing from the string. Similar to chr11 before the g., there should be a NM_ or ENST identifier before the c. notation that is missing here. Where did you get this string from?

It's definitely missing a critical piece of information. It is common practice to omit the reference sequence identifier when the broader context is known - if a particular gene is being discussed, for example. But without context, that notation makes no sense. You might want to search dbSNP/EnsEMBL/other databases by chromosome coordinate to get to that entry though - that might work.

EDIT: I went on Google and looked for a cow genes database and found one at missouri.edu. Searching by coordinate there takes me to this entry: http://128.206.116.13:8080/bovinemine/report.do?id=195310204

It lies within this feature (is it a gene? I'm not sure, I work on Human genes): http://128.206.116.13:8080/bovinemine/report.do?id=412186064

Hope this helps.
