Can sequencing determine carrier status???? - Something I should have thought of before......... (Dec/07/2010 )

Hi all,

I am interested in determining a SNP responsible for a disease in humans, So, I decided to amplify the exon and then sequence it using my PCR primers. The good news is that all that worked, my sequencing results gave me the expected results for my positive sample.

What I would like to know is whether sequencing can help, if I want to determine carrier status in my sample. If a person were

a carrier, then the PCR product (ideally) should contain both the polymorphism and the wild type nucleotide in equal amounts. So, would a sequencing read tell me that both the bases are present in the person?

Thanks
