Sampling strategies in a linguistic isolate: Results from mtDNA analysis

Sampling strategies are crucial issues in population genetics and anthropological studies. The sampling choice is related to the research question and the type of markers used. In this research, we compared two different sampling strategies in the Sardinian linguistic isolate of Carloforte (Italy).

Allele frequencies of 17 Y-chromosome short tandem repeat (STR) loci, included in the AmpFlSTR® Y-FilerTM amplification kit, were analyzed for the first time in different samplings (N=268) from Sardinia, Italy. Samples were collected from three isolated populations (N=139) and three open populations (N=129). A total of 230 unique haplotypes were detected; the observed haplotype diversity and discrimination capacity were 0.998 and 0.858, respectively. The data presented confirm that Sardinian population is well differentiated from other Italian and Mediterranean populations. Although regarded as a homogeneous population, substantial heterogeneity was detected when Sardinian isolated villages or microareas were analyzed. Our results highlights the importance of building a Sardinia-own database, organized by small areas, as a powerful tool for both forensic applications and population genetics studies.

BackgroundThe ACTN3 gene may influence performance in team sports, in which sprint action and high-speed movements, regulated by the anaerobic energy system, are crucial to the ultimate success of a match. The aim of this study was to determine the association between the ACTN3 R577X (rs1815739) polymorphism and elite team sport athletic status in Italian male athletes.MethodsWe compared the genotype and allele frequency of the ACTN3 R577X polymorphism between team sport athletes (n = 75), endurance athletes (n = 40), sprint/power athletes (n = 64), and non-athletic healthy controls (n = 192) from Italy. Genomic DNA was collected using a buccal swab. Extraction was performed according to the manufacturer’s directions provided with a commercially available kit (Qiagen S.r.l., Milan, Italy).ResultsTeam sport athletes showed a lower frequency of the 577RR genotype compared to the 577XX genotype than sprint/power athletes (p = 0.044). However, the ACTN3 R577X polymorphism was not associated with team sport athletic status compared to endurance athletes and non-athletic controls.ConclusionsOur results agree with a recent large-scale study involving athletes from Spain, Poland, and Russia. The ACTN3 R577X polymorphism was not associated with team sport athletic status compared to endurance athletes and non-athletic controls.

The aims of this work are to provide first data on novel STRs at the NOS gene regions in human populations and to test for possible correlations with mortality rate by malaria in different areas of Sardinia (Italy).

Analysis of uniparental markers reveals a complex pattern of migration within Sardinia

Abstract Background: From the genetic viewpoint, Sardinia is well differentiated from other surrounding populations. In spite of a common ancestral origin, substantial genetic heterogeneity is observed within the island. Matrimonial pattern, as well as past migration movements, may account for the complex genetic structure of Sardinia. Aim: To compare data from uniparental markers in order to highlight the migration pattern of male and female lineages and check their congruence with the demographic data. Subjects and methods: Genomic DNA was obtained from 279 unrelated males selected from three isolated villages and from three open populations representative of North, Central and South Sardinia. The hypervariable region 1 of mtDNA was sequenced and 17 Y-chromosome loci were genotyped. Parameters of within and among populations diversity were calculated and analysis of migration was performed. Results: When analysed as a whole population, demographic data show a balanced movement of males and females in Sardinia, unlike other Italian and European populations. Remarkably, when the island is divided into geographic areas, different migration patterns are clearly recognisable. Whereas North and Central Sardinia populations show a stronger male migration rate, the South Sardinia population shows a stronger female migration rate. Conclusion: Distinct migration patterns of male and female lineages affect the areas investigated differently. These past migration movements are major contributors to the complex genetic structure currently observed in the Sardinian population.
