Nuclear pseudogenes of mitochondrial DNA as a variable part of the human genome.
Novel pseudogenes homologous to the mitochondrial (mt) 16S rRNA gene were detected via different approaches. Eight pseudogenes were sequenced. Copy number polymorphism of the mtDNA pseudogenes was observed among randomly chosen individuals, and even among siblings. A mtDNA pseudogene in the Y-chromosome was observed in a YAC clone carrying only repetitive sequence tag site (STS). PCR screening of human yeast artificial chromosome (YAC) libraries showed that there were at least 5.7 x 10(5) bp of the mtDNA pseudogenes in each haploid nuclear genome. Possible involvement of the mtDNA pseudogenes in the variable part of the human nuclear genome is discussed.
