Ciliopathies Gene Panel
Ciliopathies Gene Panel Contact details Introduction Regional Genetics Service The ciliopathies are a heterogeneous group of conditions with considerable phenotypic overlap. Levels 4-6, Barclay House These inherited diseases are caused by defects in cilia; hair-like projections present on most 37 Queen Square cells, with roles in key human developmental processes via their motility and signalling functions. Ciliopathies are often lethal and multiple organ systems are affected.

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. -

Evidence of Oligogenic Inheritance in Nephronophthisis

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. -

Nine doublet microtubule pairs make up the core of each cilium, known as the axoneme. Cilia are classified as motile or immotile; non motile or primary cilia are involved in sensing the extracellular environment. These organelles mediate perception of chemo-, mechano- and osmosensations that are then transmitted into the cell via signaling pathways. They also play a crucial role in cellular functions including planar cell polarity, cell division, proliferation and apoptosis. Because of cilia are located on almost all polarized human cell types, cilia-related disorders, can affect many organs and systems. The ciliopathies comprise a group of genetically heterogeneous clinical entities due to the molecular complexity of the ciliary axoneme. -

To study congenital retinal disorders, mouse mutants have become the most important model organism.

Turn-Around-Time (TAT)* 3 - 5 weeks Acceptable Sample Types Whole Blood (EDTA) (Preferred sample type) DNA, Isolated Dried Blood Spots Saliva Acceptable Billing Types Self (patient) Payment Institutional Billing Commercial Insurance Indications for Testing Individuals with an eye disease suspected to be genetic in origin Individuals with a family history of eye disease Individuals suspected to have a syndrome associated with an eye disease Test Description This panel analyzes 211 genes that have been associated with ocular disorders. Both sequencing and deletion/duplication (CNV) analysis will be performed on the coding regions of all genes included (unless otherwise marked). All analysis is performed utilizing Next Generation Sequencing (NGS) technology. CNV analysis is designed to detect the majority of deletions and duplications of three exons or greater in size. Smaller CNV events may also be detected and reported, but additional follow-up testing is recommended if a smaller CNV is suspected. All variants are classified according to ACMG guidelines. Condition Description Diseases associated with this panel include microphtalmia, anophthalmia, coloboma, progressive external ophthalmoplegia, optic nerve atrophy, retinal dystrophies, retinitis pigementosa, macular degeneration, flecked-retinal disorders, Usher syndrome, albinsm, Aloprt syndrome, Bardet Biedl syndrome, pulmonary fibrosis, and Hermansky-Pudlak
