Hey! Yeah it think its better if they just go under the same heading because they go together and its impossible to separate them anyway...so yeah 'Genetic Factors and Etiology' should be fine...and we can add in any subheadings if we need em later... :D

Hey guys i just changed the etiology, genetic factors/ cause headings, before we had genetic factors and etiology as separate headings with cause as a subheading below genetic factors and it didn't really make sense... so is it ok if we just have the heading 'Genetic Factors and Etiology'???

Hey guys i just emailed Dr. Steve Palmer, will hope for a quick reply. Apparently he's taking the next lecture or something when we get back, but by then it will be too late, so it's best if we can arrange a meeting. Who wants to come with me to see him..........................................................................................=/

Here's an article for diagnosis and management of the disease
Hey that's heaps good, we'll compare timetables tomorrow during the lab or something, this page is coming alongggggggggggg!
--z3331469 16:00, 31 August 2011 (EST)
Happy sister 1, you are awesome! I'll do Coronary artery stenosis, Pulmonary valve stenosis, Atrial septal defect, Ventricular septal defect if you didnt already start on any... I'm doin my williams research now so hopefully, i'll have my bit up tonight! *crosses fingers* I'm so sick of readin articles... =P Is there a time we can all go meet up with the WS proff?
--Z3332178 20:37, 30 August 2011 (EST)
Hey i found out who the researcher of WS at uni is, it's Dr Steve Palmer, here's his email email@example.com, on the course outline it says that we have to make an appointment if we want to see him. We should try get together sometime this week or next week so we can go see him and ask about his current research???
--z3331556 18:51, 27 August 2011 (EST)
So i finally figured out how to reference on this thing, thought you guys might need help.... if you look on the main project page I've started to put some info up, so if you click on the edit button (on the side of each heading) the info and references come up, just copy and paste the ref name....blah blah part after your info BUT REPLACE THE PMID NUMBER WITH THE ONE YOU NEED FOR YOUR ARTICLE. When u save, the reference is automatically made in the reference heading at the bottom of the pages
Hope this makes sense lol
--z3331556 17:17, 27 August 2011 (EST)
Hey guys i've posted up some links to articles that may help in your research, they're on the reference list below. Oh and Felicia i think we should further split up the cardiovascular heading so we can research specific types and make them subheadings??? The OMIM clinical synopsis web page  has these as abnormalities associated with the heart:
Supravalvular aortic stenosis
Valvular aortic stenosis
Bicuspid aortic valve
Mitral valve prolapse
Coronary artery stenosis
Pulmonary valve stenosis
Atrial septal defect
Ventricular septal defect
which ones do you want to search???

“The behavioral phenotype of Williams syndrome: A recognizable pattern of neurodevelopment” by Colleen A. Morris The review article concludes that a person with William syndrome share distinct cognitive and behavioural features. The phenotype of a typical patient will be due to the deleted genes of chromosome 7 q11.23.
“Impaired geometric reorientation caused by genetic defect” by Laura Lakusta, Banchiamlack Dessalegn, and Barbara Landau By testing participants in a plain or single blue walled chamber, the study was able to show that William syndrome patients show a failure to reconstruct and use geometric representations of the chamber o find hidden objecs. --z3332178 22:42, 9 August 2011 (EST)

William's syndrome (WS) features a spectrum of neurocognitive and behavioral abnormalities due to a rare 1.5 MB deletion that includes about 24-28 genes on chromosome band 7q11.23. Study of the expression of these genes from the single normal copy provides an opportunity to elucidate the genetic and epigenetic controls on these genes as well as their roles in both WS and normal brain development and function. We used quantitative RT-PCR to determine the transcriptional level of 14 WS gene markers in a cohort of 77 persons with WS and 48 normal controls. Results reported here: (1) show that the expression of the genes deleted in WS is decreased in some but not all cases, (2) demonstrate that the parental origin of the deletion contributes to the level of expression of GTF2I independently of age and gender and (3) indicate that the correlation of expression between GTF2I and some other genes in the WS region differs in WS subjects and normal controls, which in turn points toward a regulatory role for this gene. Interspecies comparisons suggest GTF2I may play a key role in normal brain development.

Review Article:The genomic basis of the Williams – Beuren syndrome •Williams syndrome is a genomic disorder with symptoms including mental retardation, visuospatial impairment & overfriendliness.
•It is caused due to a hemizygous contiguous gene deletion with regards to chromosome 7q11.23.
•This review article deals with the genomic assembly of the region involved in Williams syndrome as well as the chromosomal mechanisms such as deletions and duplications and the consequences of these.

Research Article: Functional, structural and metabolic abnormalities of the hippocampl formation in Williams syndrome •In this study, neuroimaging (PET and fMRI) was used to investigate the hippocampal structure, function and metabolic integrity of 12 people with Williams syndrome compared to 12 healthy controls.
•N-acetul aspartate can be seen as a marker for synaptic activity and measures of this were reduced in those with Williams syndrome
•Although regular hippocampal size was maintained in both groups, slight changes in the shape were present.
•Through the results of the investigation, it was suggested that the neurocognitive abnormalities seen in Williams syndrome may be partly due to hippocampal dysfunction.

Abstract Although genetics is the most significant known determinant of human intelligence, specific gene contributions remain largely unknown. To accelerate understanding in this area, we have taken a new approach by studying the relationship between quantitative gene expression and intelligence in a cohort of 65 patients with Williams Syndrome (WS), a neurodevelopmental disorder caused by a 1.5 Mb deletion on chromosome 7q11.23. We find that variation in the transcript levels of the brain gene STX1A correlates significantly with intelligence in WS patients measured by principal component analysis (PCA) of standardized WAIS-R subtests, r = 0.40 (Pearson correlation, Bonferroni corrected p-value = 0.007), accounting for 15.6% of the cognitive variation. These results suggest that syntaxin 1A, a neuronal regulator of presynaptic vesicle release, may play a role in WS and be a component of the cellular pathway determining human intelligence.
- Williams Syndrome presents with a distinct pattern of intellectual disabilities that differ from normal on subtests of the WAIS-R (Wechsler Adult Intelligence Scale-Revised). Found that relative to their overall performance, WS subjects tended to do well in tests of vocabulary (Vocabulary) and abstract reasoning (Similarities, Picture Arrangement), and poorly in tests of numeracy (Arithmetic), visual-spatial (Digit Symbol, Block Design, Object Assembly), and memory (Digit Span)
- Gene expression in the tissue of interest (brain) is not possible so quantitated gene expression in lymphoblastoid (LB) cell lines
- STX1A is best known as an important component of the presynaptic SNARE complex involved in priming of synaptic vesicles for release.
- Data indicate that peripheral STX1A expression levels measured in lymphoblastoid cell lines strictly grown, is related to an emergent property of the CNS, intelligence.

Abstract Williams-Beuren syndrome (WBS) (OMIM# 194050) is a rare, most often sporadic, genetic disease caused by a chromosomal microdeletion at locus 7q11.23 involving 28 genes. Among these, the elastin gene codes for the essential component of the arterial extracellular matrix. Developmental disorders usually associate an atypical face, cardiovascular malformations (most often supravalvular aortic stenosis and/or pulmonary artery stenosis) and a unique neuropsychological profile. This profile is defined by moderate mental retardation, relatively well-preserved language skills, visuospatial deficits and hypersociability. Other less known or rarer features, such as neonatal hypercalcemia, nutrition problems in infancy, ophthalmological anomalies, hypothyroidism, growth retardation, joint disturbances, dental anomalies and hypertension arising in adolescence or adulthood, should be treated. The aim of this paper is to summarize the major points of WBS regarding: (i) the different genes involved in the deletion and their function, especially the elastin gene and recent reports of rare forms of partial WBS or of an opposite syndrome stemming from a microduplication of the 7q11.23 locus, (ii) the clinical features in children and adults with a focus on cardiovascular injury, and (iii) the specific neuropsychological profile of people with WBS through its characteristics, the brain structures involved, and learning.
