About this study
This is a a study to identify inherited disease genes. The study will use molecular techniques to map genetic diseases using techniques such as Affymetrix SNP chips. The powerful combination of the information generated by the Human Genome Project and technical advances such as microarrays enables attempts to identify genes responsible for inherited disorders more possible than ever before. Starting with even modest pedigrees of only a few individuals, or even single individuals, it is possible to identify the gene(s) involved. It is proposed to collect up to 20 ml of peripheral blood and/or buccal cell samples from subjects and relevant family members. Currently the following disorders are approved for investigation.
The current list of disorders:
Aarskog-Scott syndrome, Café-au-Lait spots, Cerebral cavernous malformation, delXp, del2q, del10p, del11q, del12p, del13q, del14q, del16q, del17q, del18q, del Xp21, Choreoathetosis, Congenital Vertical Talus (CVT), Clubfoot, Tarsal coalition and other congenital limb deformities, Cystic Fibrosis (CF)-like disease, Desbuquois syndrome, Droopy Eyelid syndrome (Ptosis), Fanconi-Bickel syndrome (FBS), FENIB (familial encephalopathy with neuroserpin inclusion bodies), FG syndrome, Idiopathic generalised epilepsy (IGE), Renpenning syndrome, transient neonatal diabetes with 6q UPD, translocation (13;14), translocation (3;8), translocation (2;18), Uncharacterized familial dementia and X-linked mental retardation (XLMR).
Read the detailed description
It is proposed to identify and recruit individuals and/or families with specified the disorders listed above. 10-20 ml (2-4 teaspoons) of peripheral blood will be collect¬ed from all adult subjects. Smaller volumes of blood would be collected from children based on their age/size. In some cases, as an adequate alternative to collecting peripheral blood, buccal cells will be collected using cheek swabs (Epicentre Biotechnologies). All relevant living members of each pedigree will be asked to partici¬pate, free of charge, on a research basis only. Genomic DNA will be extracted by standard methods and used as template for Polymerase Chain Reac¬tion (PCR) amplification reactions. Individuals will be genotyped at markers and candidate gene sequenced.
Essentially two approaches will be used:
- Circumstances that may provide knowledge of candidate genes include reviews of the literature, biology of the disease, understanding of biological pathways, chromosomal rearrangements, mutants in model organisms etc. When candidate genes exist, it is proposed to use linked microsatellite and/or single nucleotide polymorphism (SNP) PCR primer pairs on the DNA from families to determine if there is co-segregation of the disease and markers and thus linkage between the disease gene and previously mapped markers. If the disease appears to be linked to the candidate gene, PCR primers flanking all coding exons will be used to amplify the exons and intron/exon boundaries followed by sequencing to detect disease-causing mutations. A web site that enables the design of primers to amplify candidate gene exons is available (http://genome.ucsc.edu/cgi-bin/hgGateway ). If a very strong candidate gene exists, candidate gene sequencing will be performed on affected individual samples without first performing a linkage study.
- When no obvious candidate genes exist, and a family of sufficient size has been collected, it is proposed to use Affymetrix SNP microarrays to perform a human genome-wide search for linkage. We have used this approach successfully before (Shrimpton et al 2004), utilizing the whole genome linkage analysis with the Human Mapping 10K Array (Affymetrix Inc., Santa Clara, CA). The 10K Array permits the simultaneous genotyping of more than 11,200 mapped SNPs spaced throughout the human genome at 210 KB intervals. Affymetrix 100K and 500K arrays are also available. SNP genotype information will be analyzed using Varia (Silicon Genetics) and/or Merlin software. The data will be used to define a critical region. If statistically significant segregation is detected, candidate genes within the critical region will be evaluated and ranked in order of their likelihood of being the disease gene. Candidate genes will then be sequenced as detailed above.
Summary.

Questions about this trial
What is this clinical trial studying?
An observational study of Congenital Vertical Talus and Familial Encephalopathy With Neuroserpin Inclusion Bodies, run by State University of New York - Upstate Medical University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 2 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: Lack of funding.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Identification of gene/mutation responsible for disorder. (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00916903, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jan 2024.
