I assume that you wish to know if your yDNA, mtDNA, and/or autosomal DNA has a similarity to those with Sephardic ancestry. Each of these can and has been tested by various means. Two recent papers discuss autosomal connections:
Abraham’s Children in the Genome Era: Major Jewish Diaspora Populations Comprise Distinct Genetic Clusters with Shared Middle Eastern Ancestry, 2010, Ostrer et alii
and The genome-wide structure of the Jewish people, 2010, by Behar et alii. Family Finder at FTDNA and Relative Finder at 23andMe offer tests and comparisons for most people.
Behar wrote a study on Jewish mtDNA. As to yDNA, most studies are ancient (read obsolete) and incomplete as many new SNPs and clusters particularly in your R1b1b2 haplogroup confuse the issue. I would suggest a Deep Clade test from FTDNA and checking your actual data for 67 markers against http://www.familytreedna.com/public/JewishR1b/ to see if there are any matches versus those at http://www.familytreedna.com/public/R1b-U152/default.aspx
