Next Generation Mendelian Genetics: Atypical Werner Syndrome

ABSTRACT:

Werner syndrome (WS) is an adult-onset progeroid syndrome characterized by accelerated aging. The International Registry of Werner Syndrome in the Department of Pathology, University of Washington, collects WS cases from all over the world. Classical WS is caused by WRN mutations. Those who do not carry WRN are categorized as "atypical Werner syndrome." A small subset of atypical WS is caused by LMNA mutations. There also are many cases whose causes are still unknown. The purpose of this study is to identify other causative gene(s) of atypical WS.

<h4>Background</h4>Werner's syndrome is a progeroid syndrome caused by mutations at the WRN helicase locus. Some features of this disorder are also present in laminopathies caused by mutant LMNA encoding nuclear lamin A/C. Because of this similarity, we sequenced LMNA in individuals with atypical Werner's syndrome (wild-type WRN).<h4>Methods</h4>Of 129 index patients referred to our international registry for molecular diagnosis of Werner's syndrome, 26 (20%) had wildtype WRN coding regions and ...[more]

Intrauterine Levonorgestrel and Observation or Observation Alone in Preventing Atypical Endometrial Hyperplasia and Endometrial Cancer in Women With Hereditary Non-Polyposis Colorectal Cancer or Lynch Syndrome

Project description:RATIONALE: The use of intrauterine levonorgestrel may prevent atypical endometrial hyperplasia and endometrial cancer in women with hereditary non-polyposis colorectal cancer or Lynch syndrome. It is not yet known whether intrauterine levonorgestrel and observation are more effective than observation alone in preventing atypical endometrial hyperplasia and endometrial cancer in women with hereditary non-polyposis colorectal cancer or Lynch syndrome. PURPOSE: This randomized phase III trial is studying intrauterine levonorgestrel and observation to see how well they work compared with observation alone in preventing atypical endometrial hyperplasia and endometrial cancer in women with hereditary non-polyposis colorectal cancer or Lynch syndrome.

Characterization of differentially abundant proteins among Leishmania (Viannia) braziliensis strains isolated from atypical or typical lesions

Project description:Leishmania (Viannia) braziliensis is the main etiological agent of cutaneous and mucocutaneous leishmaniasis in Latin America. Reports have described non-ulcerated atypical tegumentary leishmaniasis cases caused by L. braziliensis in several regions of the world, including in patients from the Xacriabá Indigenous reserve, in São João das Missões/Minas Gerais - Brazil. Parasites isolated from these atypical clinical lesions have previously been found to be resistant to antimony-based therapeutics. In the present study, proteins displaying differential abundance in 2 strains of L. braziliensis isolated from patients with atypical lesions compared with 4 strains isolated from patients with typical lesions were identified using a quantitative proteomics approach based on tandem mass tag labeling (TMT) and mass spectrometry. A total of 532 (p value <0.05) differentially abundant proteins were identified (298 up-regulated and 234 down-regulated) in strains from atypical lesions compared to strains from typical lesions. We observed a variety of proteins with differential abundance among the studied strains. Prominent positively regulated in atypical strains included proteins which may confer a greater survival inside the macrophage, proteins related to resistance to antimony and higher peroxidase activity. Also were identified proteins suggest as new drug and vaccines target. Our data contribute to characterization of these intriguing L. braziliensis strains, and sheds new light on ACL cases has been associated with therapeutic failures.

Chromatin dysfunction facilitates stem cells aging in atypical laminopathy-based progeria Mandibuloacral dysplasia type A (MAD)

Project description:Nuclear lamins orchestrate the nuclear envelope architecture to maintain nuclear homeostasis, such as nuclear integrity and chromatin organization. The LMNA mutations lead to a variety of laminopathies, including progeroid syndrome. Other than typical Hutchinson-Gilford progeria syndrome (HGPS), the mechanism of LMNA mutation associated atypical progeria remains largely unexplored. We used patient-specific induced pluripotent stem cells (iPSCs) and their derivatives to remodel an LMNA (c.1579 C>T, p.R527C) mutation that causes Mandibuloacral dysplasia type A (MAD). Vascular lineages, including vascular smooth muscle cells (VSMCs) and endothelial cells (VECs), exhibited premature ageing phenotypes, such as genome instability and nuclear deformations, whereas neural lineages showed no obvious defects. Based on the observation that MAD-iPSCs derived mesenchymal stem cells (MSCs) also recapitulated accelerated senescence, an integrated multi-omics approach was adapted to reveal the underlying mechanisms of stem cells ageing. We found that among available human MSCs ageing models, MAD-MSCs had the highest transcriptional similarity to normal ageing hMSCs. The nuclear lamina-chromatin interaction was dramatically altered for both A and B type lamin-associating domains (LADs) as well as non-LADs binding sites, resulting in ageing-associated gene dysregulations. Chromatin state analysis further showed increased chromatin accessibility, enhancer remodelling, global chromatin compartments loss, topologically associating domains (TADs) and TAD boundaries reorganization in MAD-MSCs. These hierarchical chromatin reorganizations, coupled with gene dysregulation as consequences, expedited the MAD-MSCs ageing. Collectively, this study revealed a multilevel chromatin dysregulation contributed to ageing significantly in a laminopathy-mediated atypical progeroid syndrome.

Williams-Beuren syndrome: typical deletions versus atypical deletions of the 7q11.23 region

Project description:We have performed comparative transcriptome profile from lymphoblastoid cell lines from four Williams-Beuren syndrome patients and two patients with partial deletions of the region. The goal was to find deregulated genes specifically in WBS versus atypical deletions, and to determine the biological pathways affected in WBS patients. 6 samples were hybridized twice each: once labeled with Cy5 and once labeled with Cy3 (dye-swap). Each sample was hybridized against a pool of five controls of the same gender.
