NCT ID: NCT04797663 Recruiting - Keratosis Pilaris Clinical Trials

Long-pulsed 1064 nm Nd-YAG Laser Versus TCA 20% in Treatment of Keratosis Pilaris

Start date: March 17, 2021
Phase: Phase 4
Study type: Interventional

Keratosis pilaris (KP) is a common disorder of keratinization. There are different treatment modalities for KP with variable results. Nd:YAG laser and chemical peels are among these treatment modalities, however, there is no enough evidence in the literature regarding their efficacy. The aim of this study is to assess and compare the efficacy of long pulsed Nd:YAG laser and trichloreacetic acid 20% in treatment of keratosis pilaris.

NCT ID: NCT04722315 Recruiting - Kabuki Syndrome Clinical Trials

Study of Modified Atkins Diet in Kabuki Syndrome

Start date: April 1, 2021
Phase: Early Phase 1
Study type: Interventional

Animal models of Kabuki syndrome have showed a reversal of the cognitive phenotype with ketogenic diet. Modified Atkins diet is safer and easier tolerated than full ketogenic diet and still has the histone deacetylase inhibition believed to be responsible for the cognitive improvement. This study aims to examine a small number of adults with Kabuki syndrome before and after 12 weeks on a modified Atkins diet to determine if there is any cognitive improvement and if the diet can be tolerated.

NCT ID: NCT03855631 Completed - Kabuki Syndrome 1 Clinical Trials

Exploiting Epigenome Editing in Kabuki Syndrome: a New Route Towards Gene Therapy for Rare Genetic Disorders

Start date: September 28, 2020
Study type: Observational

Starting from isolating primary cells from affected patients, an in vitro disease model system for KS will be developed. Using alternative strategies to obtain patient-derived mesenchymal stem cells, an integrative approach will be adopted for defining both the transcriptional and epigenetic regulatory networks perturbed upon the loss of function of KMT2D. Combining the self-renewal potential of mesenchymal stem cells (MSCs) with CRISPR/Cas9 technology, an epigenome editing approach as therapeutic strategy to rescue the activity of MLL4 will be developed. A step forward is expected towards the understanding of those the molecular mechanisms governing the aetiology of Kabuki Syndrome (KS) and that the proposed in vitro disease model will provide to the scientific community an experimental system to study the KS. Importantly, the aim is to define the molecular bases of KS and to develop a therapeutic strategy that could ameliorate some of the abnormalities associated with KS.

Start date: June 8, 2018
Phase: N/A
Study type: Interventional

Mnesic function has not, at present, been evaluated in patients with Kabuki Syndrome. Some data from the neuroimagery suggest an impairment of memory function. The objective of our study is to assess the mnesic function of children with Kabuki Syndrom.

Study type: Observational [Patient Registry]

To assess the indications and diagnostic efficiency of whole genome sequencing (WGS) in pediatric patients with unexplained intellectual disability/developmental delay, multiple congenital abnormalities and other rare and undiagnosed diseases

Start date: December 4, 2015

The purpose of this study is to demonstrate the safety, tolerability and efficacy of AO+ Mist administered daily for 4 weeks to improve the appearance of skin afflicted with keratosis pilaris.

NCT ID: NCT02504502 Completed - Autism Clinical Trials

Enhancing Genomic Laboratory Reports to Enhance Communication and Empower Patients

Start date: August 2015
Phase: N/A
Study type: Interventional

Current lab reports are designed to communicate results from the laboratory to the provider; they are not designed to be accessible to patients. The investigators believe that a new type of genomic test report, tailored for patient- as well as provider-use, will enable patients to have access to information they can understand allowing them to be more involved in the management of their disorders, better navigate the health care system, and make more informed decisions about their health and health care in conjunction with their providers. This approach has the potential to improve outcomes from both the patient and provider perspectives. The investigators propose to study the research question, "Can a genomic laboratory report tailored for both providers and families of patients improve interpretation of complex results and facilitate recommended care by enhancing communication and shared decision making?"

NCT ID: NCT02451761 Completed - Clinical trials for Intellectual Disability

Apparently Balanced Chromosomal Translocation/ Next-generation Sequencing/ Intellectual Disability

Start date: April 2015
Phase: N/A
Study type: Observational

Apparently balanced chromosomal rearrangement (ABCR) associated with an abnormal phenotype is a rare but problematic event. It occurs in 6% of de novo reciprocal translocations and 9% of de novo inversions. Abnormal phenotype, including intellectual disability and / or multiple congenital anomalies (ID/MCA) may be explained either by associated cryptic genomic imbalances detectable by array-CGH or by gene disruption at the breakpoint. However, breakpoint cloning using conventional methods (i.e., fluorescent in situ hybridization (FISH), Southern blot) is often laborious and time consuming and cannot be performed routinely. Without complete investigation of these rearrangements, genetic counseling is a real challenge. Recently, the investigators and others showed that Next-Generation Sequencing (NGS) is a powerful and rapid technique to characterize ABCR breakpoints at the molecular level. The ANI project (ABCR NGS ID) aims at characterizing at the molecular level ABCR in 55 patients presenting with intellectual disability and/or multiple congenital anomalies (ID/MCA) using NGS. The investigators make the hypothesis that ABCR account for the patient phenotype, either by gene disruption or position effect, since genomic imbalance would have been previously excluded by array-Comparative Genomic Hybridization (CGH). The ANI project is a 3-year-long study that will be conducted by a consortium of 21 partners, including 19 french hospital cytogenetics laboratories, a research team (TIGER), and a cellular biotechnology center. Patients will be recruited by each Cytogenetics laboratory. ABCR breakpoints will be molecularly characterized by NGS and a first bio-informatics analysis. The results will be verified by amplification of junction fragments by polymerase Chain Reaction (PCR) followed by Sanger sequencing, allowing the localization of breakpoints at the base-pair level. In some complex cases, FISH experiment will be necessary to clarify the results. A second bio-informatics analysis will then determine breakpoints' characteristics (sequence, repeated elements, gene and regulatory elements). Finally, for each breakpoint, gene expression studies will be performed including the gene disrupted by the breakpoint and two neighboring genes. All these data, together with those already available in the literature and databases will be integrated to determine if the gene could account for the patient's phenotype, allowing an appropriate genetic counseling. This project will identify new candidate genes involved in ID and developmental anomalies. It will also contribute to the development and evaluation of NGS as a diagnostic tool for ABCR and ID/MCA. It will also allow unraveling mechanisms and functional consequences of ABCR, in particular in term of position effect. In conclusion, the ANI project will contribute to the improvement of diagnostic management and genetic counseling of patients with ID/MCA and ABCR. It will also contribute to the understanding of ABCR physiopathology and to the unraveling of pathway involved in development and brain function, thus improving genetic counseling for ID/MCA patients in general.

NCT ID: NCT01995305 Available - Fanconi Anemia Clinical Trials

Use Massive Parallel Sequencing and Exome Capture Technology to Sequence the Exome of Fanconi Anemia Children and Their Patents

Start date: n/a
Phase: N/A
Study type: Expanded Access

Fanconi anemia is a rare autosomal or sex linked recessive genetic disease. The disease is characterized by bone marrow hematopoiesis failure, multiple congenital abnormalities, and susceptibility to neoplastic diseases. The cells of FA patients are extremely sensitive to MMC and DEB. The symptoms and ages of FA patients are different, so by comparing the exome of FA patients and their parents, the mutations that were accumulated in FA patients could be found, and these genes might be sensitive to repairment and be important for hematopoiesis maintainance.
