Welcome!
Hello, JillianSherer, and welcome to Wikipedia! My name is Ian and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.

I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing. If you have any questions, please don't hesitate to contact me on my talk page. Ian (Wiki Ed) (talk) 18:49, 5 September 2018 (UTC)

Welcome
Welcome to Wikipedia! We have compiled some guidance for new healthcare editors:
 * 1) Please keep the mission of Wikipedia in mind. We provide the public with accepted knowledge, working in a community.
 * 2) We do that by finding high quality secondary sources and summarizing what they say, giving WP:WEIGHT as they do.  Please do not try to build content by synthesizing content based on primary sources.
 * 3) Please use high-quality, recent, secondary sources for medical content (see WP:MEDRS; for the difference between primary and secondary sources, see the WP:MEDDEF section.) High-quality sources include review articles (which are not the same as peer-reviewed), position statements from nationally and internationally recognized bodies (like CDC, WHO, FDA), and major medical textbooks. Lower-quality sources are typically removed. Please beware of predatory publishers – check the publishers of articles (especially open source articles) at Beall's list.
 * 4) The ordering of sections typically follows the instructions at WP:MEDMOS. The section above the table of contents is called the WP:LEAD. It summarizes the body. Do not add anything to the lead that is not in the body. Style is covered in MEDMOS as well; we avoid the word "patient" for example.
 * 5) We don't use terms like "currently", "recently," "now", or "today". See WP:RELTIME.
 * 6) More generally see WP:MEDHOW, which gives great tips for editing about health -- for example, it provides a way to format citations quickly and easily
 * 7) Citation details are important:
 * 8) *Be sure cite the PMID for journal articles and ISBN for books
 * 9) *Please include page numbers when referencing a book or long journal article, and please format citations consistently within an article.
 * 10) *Do not use URLs from your university library that have "proxy" in them: the rest of the world cannot see them.
 * 11) *Reference tags generally go after punctuation, not before; there is no preceding space.
 * 12) We use very few capital letters (see WP:MOSCAPS) and very little bolding. Only the first word of a heading is usually capitalized.
 * 13) Common terms are not usually wikilinked; nor are years, dates, or names of countries and major cities. Avoid overlinking!\
 * 14) Never copy and paste from sources; we run detection software on new edits.
 * 15) Talk to us! Wikipedia works by collaboration at articles and user talkpages.

Once again, welcome, and thank you for joining us! Please share these guidelines with other new editors.

Genetics
Osteogenesis imperfecta is a genetic disorder generally caused by dominant mutations in the COL1A1 and COL1A2 genes found on chromosome 17. These dominant mutations cause defects in the formation of collagen 1 which is responsible for the strengthening of bone. A component of collagen 1 is produced by the COL1A1 gene known as the pro-alpha1 chain. Therefore, if there are mutations in the pro-alpha1 chain, the likely hood of a child being born with Osteogenesis Imperfecta is increased. Another version of the disease is caused by autosomal recessive mutations in several genes including CRTAP, BMP1, CREB3L1, IFITM5, FKBP10, LEPRE1, PPIB, SP7, PLOD2, TMEM38B, SERPINF, SERPINH1, SEC24D, SPARC, and WNT1. These autosomal recessive mutations are responsible for causing defects in the proteins that interact with collagen. This causes them to be less responsible in causing severe cases of Osteogenesis Imperfecta. However, the SERPINH1 gene has been known to produce autosomal recessive versions of OI especially when seen in the homozygous state. A study was done in ancestral family members who showed symptoms of OI and it was seen that those individuals had the homozygous allelic frequency and therefore, had the disorder. Although extremely rare, there have been a few reported cases of an X-linked version of OI. A pedigree from Thailand was analyzed in which 6 of the 12 males were affected with OI. All of these males had been susceptible to bone fractures since gestation and exhibited a majority of the symptoms of OI. The mothers of all 6 of the males exhibited heterozygous allelic frequencies for a mutation in the genes responsible for causing OI. All of these males developed either OI type III or IV which shows that the X-linked version of the disorder is increasingly more volatile than both the dominant and the recessive forms of the disease. In another study done on X-linked OI showed that several individuals had a variant (rs140121121) in the PLS3 gene which is extremely rare and could be one of the reasons that X-linked OI is also rare. The PLS3 gene is responsible for forming a bone-regulatory protein. In the dominant form of the disorder, it has been seen that a WNT1 homozygous frameshift mutation as well as a single, recurrent nucleotide mutation in the IFITM5 gene are both located at the most 5’ end of their occurring DNA sequences. As a result of the location of these mutations, it has been hypothesized that 5’ mutations in genes related to bone growth and development are likely one of the main causes of severe OI.

Genetic influences
Osteogenesis Imperfecta is a genetic disorder that is caused by dominant mutations in the COL1A1 and COL1A2 genes found on chromosome 17.


 * This is a primary source. It is a case report. Please read WP:MEDRS

These dominant mutations cause defects in the formation of collagen 1 which is responsible for the strengthening of bone. A component of collagen 1 is produced by a section of the COL1A1 gene referred to as the pro-alpha1 chain. Children born with mutations in the pro-alpha1 chain, have a greater chance of being born with Osteogenesis Imperfecta. alternate versions of the disease are caused by autosomal recessive mutations in multiple genes including CRTAP, BMP1, CREB3L1, IFITM5, FKBP10, LEPRE1, PPIB, SP7, PLOD2, TMEM38B, SERPINF, SERPINH1, SEC24D, SPARC, and WNT1. These autosomal recessive mutations are responsible for causing defects in the proteins that interact with collagen. The autosomal recessive mutations cause the collagen proteins to be less effective and lead to symptoms involving Osteogenesis Imperfecta. Mutations in the SERPINH1 gene also lead to autosomal recessive versions of OI when seen in the homozygous state.


 * This is another case report. These are NOT sufficient sources.

There is a direct correlation between the homozygous state of a gene and the autosomal recessive versions of the OI disorder. A study was done in ancestral family members who showed symptoms of OI which showed that those individuals who carried the homozygous allelic frequency, developed the disorder. In addition, there have been reported cases of an X-linked version of OI. A pedigree from Thailand was analyzed in which 6 of the 12 male siblings were affected with OI.


 * This is a third case report...

All of the males had been susceptible to bone fractures since gestation and exhibited a majority of the symptoms of OI. The mothers of all 6 of the males exhibited heterozygous allelic frequencies for a mutation in the genes responsible for causing OI. All of the males were diagnosed with either OI type III or IV which determined that the X-linked version of the disorder is increasingly more volatile than both the dominant and the recessive forms of the disease. An additional study that was done on individuals with X-linked OI exhibited that several individuals had a variant (rs140121121) in the PLS3 gene which led to their development of the OI disorder.


 * This is a small case series.

The PLS3 gene is responsible for forming a bone-regulatory protein in humans. In the dominant form of the OI disorder, a WNT1 homozygous frameshift mutation as well as a single, recurrent nucleotide mutation in the IFITM5 gene are both located at the most 5’ end of their occurring DNA sequences. The 5’ mutations result in issues regarding bone growth and development. Individuals who carry 5’ mutations on the IFITM5 gene have reportedly been linked with carrying the dominant alleles for the gene. The dominant form of the genes for the Osteogenesis Imperfecta disease cause severe cases of OI ranging from OI type III to OI type V.


 * And this is a case report.
