individuals, the 16184C→T mutation was found to be present in
three individuals of West Eurasian origin, giving a frequency of
0.0007%. In a personal database comprising about 37,000 control
region records (Dr M. Pala, personal communication), the HSV1
sequence with the single mutation 16184C→T was also present in
three samples (one from Crete and two from Italy), giving a
mutation frequency for 16184C→T of 0.00008%. All three samples
belonged to the mtDNA haplogroup H. On the left, the locks of
