Being expressed in all cell types, they are involved in almost all physiological processes, including sense perception, neurotransmission, muscle contraction, secretion, immune response, cell proliferation, and differentiation. Due to the widespread tissue distribution of ion channels and their physiological functions, mutations in genes encoding ion channel subunits, or their interacting proteins, are responsible for inherited ion channelopathies. These diseases can range from common to very rare disorders and their severity can be mild, Edited by: disabling, or life-threatening.

The Molecular Basis for Dent's Disease: an X-Linked
Proc. R. Coll. Physicians Edinb. 1997; 27: 167-177 THE MOLECULAR BASIS FOR DENT’S DISEASE: AN X-LINKED HYPERCALCIURIC NEPHROLITHIASIS DISORDER* R. V. Thakker,† MRC Molecular Endocrinology Group, MRC Clinical Sciences Centre, Royal Postgraduate Medical School, Hammersmith Hospital, Du Cane Road, London SUMMARY Renal stone disease, which affects 12% of males and 5% of females by the seventh decade, occurs as an inherited disorder in 45% of patients when it is most commonly associated with hypercalciuria. The biochemical basis for hereditary nephrolithiasis and hypercalciuria is unknown, and this has therefore been investigated by a ‘positional cloning’ approach. As a first step in this approach, the chromosomal location of Dent’s disease, which is an unusual form of the renal Fanconi syndrome was determined. An X-linked inheritance for Dent’s disease, which is characterised by a low molecular weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis and renal failure, was indicated by the observation of a greater disease severity in males and an absence of male to male transmission in five British families. X-linked polymorphic genetic markers were used in linkage studies of these families and the gene was mapped to Xp11. In addition, in one family with Dent’s disease, a microdeletion involving the DNA probe M27β was identified. This microdeletion was further characterised by using yeast artificial chromosomes (YACs) and its size was estimated to be 515 Kb. A search for renal expressed genes from this region identified a novel gene encoding a chloride channel (CLCN5) with similarities to a family of voltage-gated chloride channels. Molecular genetic studies of CLCN5 demonstrated that mutations, which resulted in a functional loss, were associated with Dent’s disease. -

A Genetic Investigation of the Muscle and Neuronal Channelopathies: from Sanger to Next – Generation Sequencing
A Genetic Investigation of the Muscle and Neuronal Channelopathies: From Sanger to Next – Generation Sequencing Alice Gardiner MRC Centre for Neuromuscular Diseases and UCL Institute of Neurology Supervised by Professor Henry Houlden and Professor Mike Hanna 1 Declaration I, Alice Gardiner, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Signature A~~~ . Date ~.'t..J.q~ l.?,.q.l.~ . 2 Abstract The neurological channelopathies are a group of hereditary, episodic and frequently debilitating diseases often caused by dysfunction of voltage-gated ion channels. This thesis reports genetic studies of carefully clinically characterised patient cohorts with different episodic neurological and neuromuscular disorders including paroxysmal dyskinesias, episodic ataxia, periodic paralysis and episodic rhabdomyolysis. Genetic and clinical heterogeneity has in the past, using traditional Sanger sequencing methods, made genetic diagnosis difficult and time consuming. This has led to many patients and families being undiagnosed. Here, different sequencing technologies were employed to define the genetic architecture in the paroxysmal disorders. Initially, Sanger sequencing was employed to screen the three known paroxysmal dyskinesia genes in a large cohort of paroxysmal movement disorder patients and smaller mixed episodic phenotype cohort. A genetic diagnosis was achieved in 39% and 13% of the cohorts respectively, and the genetic and phenotypic overlap was highlighted. Subsequently, next-generation sequencing panels were developed, for the first time in our laboratory. Small custom-designed amplicon-based panels were used for the skeletal muscle and neuronal channelopathies. They offered considerable clinical and practical benefit over traditional Sanger sequencing and revealed further phenotypic overlap, however there were still problems to overcome with incomplete coverage.
