“…As a part of the comprehensive anthropological research on the population structure of Croatian island isolates, microsatellite DNA from different subpopulations has been previously analyzed to determine genetic diversity, population structure, and the degree of isolation of island populations (9). Similar studies were also conducted on a representative sample of the general Croatian population and other isolated populations from Southeastern Europe (10)(11)(12).…”

We reviewed data collected during several studies concerning the genetic isolate of Carloforte (Sardinia, Italy) and analyzed new data on Y-chromosome markers.Carloforte is also a language island, where people still speaks Tabarchino, an archaic form of Ligurian dialect. Demographic data indicate that, in the early years of its history, Carloforte population was characterized by a high degree of endogamy and consanguinity rates that started to decrease around 1850, when marriages with Sardinian people began to occur more frequently. Cultural factors, mainly language, account for the high endogamy. Genetic data from classical markers, mtDNA and Ychromosome markers confirmed the strong isolation of Carloforte population, which appears significantly different from the neighboring population of Sardinia. Analysis of mtDNA emphasizes the crucial aspect of sampling strategy: two different samplings of the same population, one based on founder surnames, while the other based on grandparents' criterion, gave different results. Founder surnames sampling is not affected by recent events, and therefore better describes the ancestral population.Whereas, grandparents' criterion sampling gives a picture of the present population, shaped by more recent events, like migration and gene flow. This review further supports the notion that a comprehensive approach, including a detailed knowledge of the history of the population and the collection of different samplings, is essential in anthropology for reconstructing past and recent events that contributed to establish the present genetic structure of the population. Likewise, it is essential in medical genetics to identify genes involved in complex diseases. An ideal scenario is offered by a genetic isolate with a recent, and well documented, history, like Carloforte, which can be a paradigm for this type of investigations.Pre-print version. Visit
