Abstract

A 9-bp deletion first described in the mitochondrial DNA (mtDNA) for East Asian, Polynesian or Indian American populations of the B haplogroup is now discovered in Slavs. The Russian family carrying that deletion belongs to a new branch of the T haplogroup as deduced from D-loop sequence and haplogroup-specific restriction fragment length polymorphism analysis. One family member had a Kearns-Sayre syndrome with a 5.5 kb mtDNA deletion. This family also presented a long C-stretch in the D-loop. Whether or not the formation of the 5.5 kb deletion might be related to the 9-bp deletion or to the long C-stretch in the D-loop is discussed.
