CAV3 causing CMH 192600 The disease is caused by mutations affecting the gene represented in this entry. A hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death. [read more] 14672715
COA5 causing MT-C4D 220110 The disease is caused by mutations affecting the gene represented in this entry. A disorder of the mitochondrial respiratory chain with heterogeneous clinical manifestations, ranging from isolated myopathy to severe multisystem disease affecting several tissues and organs. Features include hypertrophic cardiomyopathy, hepatomegaly and liver dysfunction, hypotonia, muscle weakness, exercise intolerance, developmental delay, delayed motor development and mental retardation. Some affected individuals manifest a fatal hypertrophic cardiomyopathy resulting in neonatal death. A subset of patients manifest Leigh syndrome. [read more] 21457908
COQ2 causing COQ10D1 607426 The disease is caused by mutations affecting the gene represented in this entry. An autosomal recessive disorder with variable manifestations consistent with 5 major phenotypes. The phenotypes include an encephalomyopathic form with seizures and ataxia; a multisystem infantile form with encephalopathy, cardiomyopathy and renal failure; a predominantly cerebellar form with ataxia and cerebellar atrophy; Leigh syndrome with growth retardation; and an isolated myopathic form.

COQ9 causing COQ10D5 614654 The disease is caused by mutations affecting the gene represented in this entry. A form of coenzyme Q10 deficiency, an autosomal recessive disorder with variable manifestations consistent with 5 major phenotypes. The phenotypes include an encephalomyopathic form with seizures and ataxia; a multisystem infantile form with encephalopathy, cardiomyopathy and renal failure; a predominantly cerebellar form with ataxia and cerebellar atrophy; Leigh syndrome with growth retardation; and an isolated myopathic form.

COX10 causing MT-C4D 220110 The disease is caused by mutations affecting the gene represented in this entry. A disorder of the mitochondrial respiratory chain with heterogeneous clinical manifestations, ranging from isolated myopathy to severe multisystem disease affecting several tissues and organs. Features include hypertrophic cardiomyopathy, hepatomegaly and liver dysfunction, hypotonia, muscle weakness, exercise intolerance, developmental delay, delayed motor development and mental retardation. Some affected individuals manifest a fatal hypertrophic cardiomyopathy resulting in neonatal death. A subset of patients manifest Leigh syndrome. [read more] 10767350

COX14 Defects in COX14 may be a cause of a mitochondrial disorder presenting with severe congenital lactic acidosis and dysmorphic features associated with a COX assembly defect. Other features include brain hypertrophy, diffuse alteration of the white-matter myelination, and numerous cavities in the parieto-occipital region, brainstem, and cerebellum, as well as hepatomegaly, hypertrophic cardiomyopathy, renal hypoplasia, and adrenal-gland hyperplasia.

COX15 causing CEMCOX2 615119 The disease is caused by mutations affecting the gene represented in this entry. An infantile disorder, with a rapidly progressive fatal course, characterized by cytochrome c oxidase deficiency. Clinical features include microcephaly, encephalopathy, hypertrophic cardiomyopathy, persistent lactic acidosis, respiratory distress, hypotonia and seizures. Postmortem cardiac muscle studies show marked complex IV deficiency. Complex IV activity is only slightly decreased in the skeletal muscle. [read more] 12474143

COX6B1 causing MT-C4D 220110 The disease is caused by mutations affecting the gene represented in this entry. A disorder of the mitochondrial respiratory chain with heterogeneous clinical manifestations, ranging from isolated myopathy to severe multisystem disease affecting several tissues and organs. Features include hypertrophic cardiomyopathy, hepatomegaly and liver dysfunction, hypotonia, muscle weakness, exercise intolerance, developmental delay, delayed motor development and mental retardation. Some affected individuals manifest a fatal hypertrophic cardiomyopathy resulting in neonatal death. A subset of patients manifest Leigh syndrome. [read more] 18499082
CPT2 causing CPT2D 255110 The disease is caused by mutations affecting the gene represented in this entry. Autosomal recessive disorder characterized by recurrent myoglobinuria, episodes of muscle pain, stiffness, and rhabdomyolysis. These symptoms are triggered by prolonged exercise, fasting or viral infection and patients are usually young adults. In addition to this classical, late-onset, muscular type, a hepatic or hepatocardiomuscular form has been reported in infants. Clinical pictures in these children or neonates include hypoketotic hypoglycemia, liver dysfunction, cardiomyopathy and sudden death. [read more] 7711730

CPT2 causing CPT2DI 600649 The disease is caused by mutations affecting the gene represented in this entry. A disorder of mitochondrial long-chain fatty acid oxidation characterized by hepatic or hepato-cardio-muscular manifestations with onset in infancy. Clinical features include hypoketotic hypoglycemia, lethargy, seizures, hepatomegaly, liver dysfunction, cardiomegaly and dilated cardiomyopathy. [read more]
