About us

One LEFKOWITZ member of the study represents a LEFKOWITZ ancestor (haplogroup J2) with Dupuytren's Contracture. This is a disorder of the connective tissue in the hand, where one or more fingers, usually the ring finger and pinky, are curled toward the palm. The disorder is inherited, but *not* along the sex chromosomes. Therefore it is not passed along from generation to generation on the Y-DNA chromosome, and would not be expected to occur more commonly in the LEFKOWITZ ancestral line. I include the information here only because, since it is hereditary and is transmitted on autosomal genes, it is possible that other LEFKOWITZ family members may also have the disorder. You can find more information on Dupuytren's Contracture at the following link:
