A 24 bp duplication in the CHIT1 gene (H allele) is associated with a deficiency in the activity of chitotriosidase, an enzyme with the capability to hydrolyse chitin. A recent study in European and two sub-Saharan populations suggested a relationship between the presence of the mutation, improved environmental conditions, and the disappearance of parasitic diseases, including Plasmodium falciparum...
This study reports the first data on Y-chromosome-specific short tandem repeat (STR) haplotype frequencies, in the population of the island of Sicily (Italy), based on the combination of alleles at the following 10 Y-chromosome loci DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, and DYS439. In a total of 117 males, 108 unique haplotypes were observed, with 99 of them being...
