Tau gene (MAPT) sequence variation among primates

Abstract

Filamentous tau deposits are a defining feature of a number of human neurodegenerative diseases. Apes and monkeys have been reported to be differentially susceptible to developing tau pathology. Despite this, only little is known about the organisation and sequence of Tau from nonhuman primates. Here we have sequenced Tau exons 1-13, including flanking intronic regions, and the region in intron 9 that contains Saitohin in chimpanzees, gorillas, and gibbons. Partial sequences were obtained for cynomolgus macaque and green monkey. Chimpanzee brain tau was 100% identical to human tau. Identities were 99.5% for gorilla tau and 99.0% for gibbon tau. Chimpanzee DNA was polymorphic for a repeat in intron 9, which was present in human and gorilla tau, and for the nucleotide at position +29 of the intron that follows exon 10. As was the case of the other nonhuman primates examined, chimpanzee DNA was homozygous for nucleotides used to define the H2 haplotype in human Tau. These differences between human and chimpanzee Tau may contribute to the apparent resistance of chimpanzee brain to developing tau pathology. Sequencing of Saitohin revealed an intact open reading frame in chimpanzee and gorilla, but not in gibbon or macaque.
