We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

Leber Congenital Amaurosis Due to CEP290 Mutations – Severe Vision Impairment with a High Unmet Medical Need: a Review Author and Journal Details: Bart P
This plain-language summary (or PLS) describes a paper on Leber congenital amaurosis 10 that was published in a medical journal called “Retina”. Title of the paper: Leber congenital amaurosis due to CEP290 mutations – severe vision impairment with a high unmet medical need: a review Author and journal details: Bart P. Leroy, David G. Birch, Jacque L. Duncan, Byron L. Lam, Robert K. Koenekoop, Fernanda B. O. Porto, Stephen R. Russel, Aniz Girach. Retina 2021;doi:10.1097/IAE.0000000000003133. Online ahead of print. What does this paper report on? • The authors of this paper reviewed what scientists know about the genetic eye disease called Leber congenital amaurosis 10 (also known as LCA10). They looked at the scientific articles on this subject that have been published in high-quality medical journals Why was this research needed? • Tying together separate pieces of scientific evidence about a disease can help us to understand the disease better. It also helps identify where there may be areas of care for people with the disease that need to be improved. We call these gaps “unmet medical needs” • Bringing evidence together in this way is especially important for rare diseases as it improves awareness among healthcare professionals of the needs of people living with the disease The authors of the paper are expert eye doctors working at specialist centers in Belgium, Brazil, Canada, and the USA; one of the authors is an employee of ProQR Therapeutics. This PLS has been developed in collaboration with Bart Leroy (an author on the original paper), Francesca Diodati and Matthew Carr, with medical writing assistance provided by ApotheCom. -

ABSTRACT Signaling from the primary cilium regulates kidney tubule development and cyst formation. However, the mechanism controlling targeting of ciliary components necessary for cilium morphogenesis and signaling is largely unknown. Here, we studied the function of class II phosphoinositide 3-kinase-C2a (PI3K-C2a)inrenal tubule-derived inner medullary collecting duct 3 cells and show that PI3K-C2a resides at the recycling endo- some compartment in proximity to the primary cilium base. In this subcellular location, PI3K-C2a controlled the activation of Rab8, a key mediator of cargo protein targeting to the primary cilium. -

Twenty-five percent of nephronophthisis cases are caused by large homozygous deletions of NPHP1, but six genes responsible for nephronophthisis have been identified. Because oligogenic inheritance has been described for the related Bardet-Biedl syndrome, we evaluated whether mutations in more than one gene may also be detected in cases of nephronophthisis. Because the nephrocystins 1 to 4 are known to interact, we examined patients with nephronophthisis from 94 different families and sequenced all exons of the NPHP1, NPHP2, NPHP3, and NPHP4 genes. In our previous studies involving 44 families, we detected two mutations in one of the NPHP1–4 genes. Here, we detected in six families two mutations in either NPHP1, NPHP3, or NPHP4, and identified a third mutation in one of the other NPHP genes. Furthermore, we found possible digenic disease by detecting one individual who carried one mutation in NPHP2 and a second mutation in NPHP3. -
Renal Cystic Disorders Infosheet 6-14-19
Next Generation Sequencing Panel for Renal Cystic Disorders Clinical Features: Renal cystic diseases are a genetically heterogeneous group of conditions characterized By isolated renal disease or renal cysts in conjunction with extrarenal features (1). Age of onset of renal cystic disease ranges from neonatal to adult onset. Common features of renal cystic diseases include renal insufficiency and progression to end stage renal disease (ESRD). Identification of the genetic etiology of renal cystic disease can aid in appropriate clinical management of the affected patient. Our Renal Cystic Disorders Panel includes sequence and deletion/duplicaton analysis of all 79 genes listed below.
