Gene Position c.

Question

[L_LANKA]

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!!!

See this page for hgvs record format explanation. Specifically this section.

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?

This information from book about genetics of cows

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.
