The genotype is all DNA of an individual (usually summarized as the variants from the reference genome). AFAIK COSMIC only has mutations of variants related to a disease, so it is not exactly a genotype. The phenotype for each mutation or variant is that of the disease to which is related.

Thanks.  After looking a bit more I realized what I want is both germline and somatic variants for each cell line.  I still haven't figured out how to get that though.

Which cell line are you talking about? COSMIC doesn't store information of cell lines.

# COSMIC Genotypes and Phenotypes

(Asked by: username_0 on 2018-01-31)

I'm trying to find files containing genotypes and phenotypes for cell lines in COSMIC. On their [downloads page](https://cancer.sanger.ac.uk/cosmic/download) I found links for mutation data, which I guess could be converted to genotypes, but I haven't been able to find any phenotype information. I'm specifically interested in drug sensitivity information. Does anyone know if it's possible to get more user friendly genotype files and whether phenotype data exists publicly?

It seems like I was wrong and COSMIC does store information about cell lines.

You need to download the files from Genotypes:

You need to register (and get a license) to be able to download the data. Presumably the cell lines are described in the heading of the file. Then you can sort them out by cell line.

Then once you know the germ line identifier look for the paper describing it to know more about their phenotype. (But maybe there is a database with phenotype of known cell lines)
