The 14 different outcomes reported in 13 articles will be discussed as follows. SLE is considered to be a genetically 10 candidate genes complex autoimmune disorder that exhibits diverse incidence rates according to the ancestry group and presents heterogeneous clinical and laboratory features The study developed by Barbosa et al.
The only SLE self-declared as a black patient showed a greater degree of African ancestry However, the patient also presented a significant contribution of European ancestry Significant differences were identified in cases and controls for individuals with EUR and AFR ancestry from a broad genomic composition obtained from a series of individuals with SLE.
The interest in researching ancestry contributions in individuals infected with Leishmaniachagasi VL ,in endemic peri-urban areas of Natal city, by Ettinger et al. However, no clear significant difference in the total proportions of population miscegenation among the three clinical phenotype groups was noted Concerning another infectious disease, malaria infected people were investigated for ancestry component identification.
Falciparum-infected, although the significance of these results was affected by the lack of a control miscegenation group, which is a potential leading factor. A miscegenation control is essential in genetic epidemiological studies carried out in Latin American populations, where large interindividual differences in the race mix are recurrent Considering this, Tarazona et al.
In addition, Furini et al. However, a downward trend in the TNFA allele frequency was noted with increasing European ancestry It should be noted that Furini et al. For sickle-cell anaemia 32 , one study was carried out in Bahia, Northeast Region, Brazil, with noteworthy results. We used the following key words and combinations of keywords to focus our search specifically in the area of genealogy and ancestry testing: genealogy, genealogy service, recreational genealogy, genetic genealogy, family history, family tree, ancestry, combined with the words company OR service OR organisation OR provide OR business.
We excluded key words such as DNA testing as they moved the search into the domain of clinical testing which was outside the focus of this paper. The search revealed numerous companies offering a wide range of genealogy and genetic services and several types of ancestry tests. We excluded companies or laboratories that primarily offer a specific type of test other than ancestry e.
Because many companies had multiple locations and provided services online, we abandoned the location criteria.
To ensure that no companies previously studied were overlooked, the list of genetic genealogy companies produced by Royal et al. Table 1 Characteristics of companies included in the analysis Full size table We conducted a directed content analysis [ 17 ] to validate our theory that for consent to be informed, individuals should be notified of the potential implications of participation on their family and relatives.
All documents were imported and coded using NVivo 10 to facilitate the analysis. Initial codes were generated from the research questions that guided but did not constrain the analysis. Codes were developed and iteratively revised. They included but were not limited to consent for the individual, alternative forms of agreement, consent for third parties, proof of consent and family considerations.
In the first stage of the analysis, companies were placed in categories based on the services provided. Next, detailed charts were produced that included coded sections of text for each group. Similarities and differences in text were compared; we also highlighted where text was included or when it was missing. Based on these tables we were able to judge whether there was overt discussion of the implications for others as a result of consenting to participate.
They help users discover their distant relatives through access to census records, marriage and death records, military records, etc. Clients provide personal information name, gender, year of birth, address etc. Clients may keep their family histories private if they wish. Alternatively, they may choose to make their histories openly available enabling other service users to search these histories for common relatives. AncestryHealth, which focuses on health history, suggests clients may wish to share their AncestryHealth records with their physicians [ 18 ].
The majority of the companies eight of ten also recognise that potential complications may arise from providing and sharing genealogical information that relates to individuals other than the client. This is evidenced by the frequent presence of statements emphasising that it is the responsibility of the client to obtain consent from living family members prior to sharing information about them on the website and to make the implications of that consent clear.
On some parts of the website, you can publish things including your family tree , make comments or participate on forums. If you do, you must not: publish something that you do not own the copyright in or have permission to publish it from the copyright owner ; […]; or share the personal information of living people without their permission.
Concerns over ownership of samples as cited by these companies could be interpreted to reflect the fact that in some countries, such as the UK, legislation is in place to protect against the collection and use of DNA samples without the explicit consent of the person from whom it was taken [ 23 ]. The remaining four companies do not have a consent by use statement and no specific mention is made by any of the companies about the ethical implications for third parties, such as possible adverse psychological reactions to genetic ancestry data [ 12 ].
Limitations of an Integrative Review The combination and complexity of incorporating diverse methodologies can contribute to lack of rigor, inaccuracy, and bias. Methods of analysis, synthesis, and conclusion-drawing remain poorly formulated. Issues related to combining empirical and theoretical reports.
In the same year, the date the new year began was changed. We excluded key words such as DNA testing as they moved the search into the domain of clinical testing which was outside the focus of this paper.
The Genealogical Proof Standard created by the Board for Certification of Genealogists is widely distributed in seminars, workshops, and educational materials for genealogists in the United States. When you print articles, set the printer to print two pages per sheet; the result is almost always large enough to read, and it helps minimize the expense. First, read the abstract because this often helps eliminate unrelated research. Anything you read that might be relevant to your research should be written down, along with any citations that go with it, and an abbreviated citation of the source you are getting the information from.
Therefore, it is an eminently geographic disease, the product of a well-succeeded evolutionary strategy of humans to cope with malaria
At the same time we searched using the search engine Google for companies providing recreational genealogy services, genetic ancestry testing and conducting related research. In addition to copying errors, compiled sources such as published genealogies and online pedigree databases are susceptible to misidentification errors and incorrect conclusions based on circumstantial evidence.
I write these down exactly as they appear, and put them in quotation marks on my index cards. Each research group decided whether to use one or more AIMs. Although baptismal dates are often used to approximate birth dates, some families waited years before baptizing children, and adult baptisms are the norm in some religions. This step is not solely for making a decision about the relevance of an article to your research.
The Genealogical Proof Standard created by the Board for Certification of Genealogists is widely distributed in seminars, workshops, and educational materials for genealogists in the United States. In , the Board for Certification of Genealogists published their first manual of standards. Compilers sometimes draw hasty conclusions from circumstantial evidence without sufficiently examining all available sources, without properly understanding the evidence, and without appropriately indicating the level of uncertainty.
