Cowden syndrome (CS, MIM 158350) is an autosomal dominant disorder with age related penetrance characterised by multiple hamartomas and a high risk of breast, thyroid, and perhaps other cancers. These ...

Arrhythmogenic right ventricular cardiomyopathy is a rare clinical entity characterised by fibro-fatty replacement of myocardium, mainly involving right ventricular free wall, leading to malignant ...

Rubinstein-Taybi syndrome (RTS) is an archetypical genetic syndrome that is characterised by intellectual disability, well-defined facial features, distal limb anomalies and atypical growth, among ...

An association between Gaucher disease and Parkinson disease has been demonstrated by the concurrence of Gaucher disease and parkinsonism in rare patients and the identification of glucocerebrosidase ...

Schwartz-Jampel syndrome is a rare autosomal recessive disorder. Joint contractures, generalised myotonia, skeletal anomalies, and facial dysmorphism are common features; malignant hyperthermia is a ...

Background Myoclonic epilepsy with ragged-red fibres (MERRF) and mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) are established phenotypes of mitochondrial ...

Background: Patients with cystic fibrosis with the same mutations in the cystic fibrosis transmembrane conductance regulator ( CFTR ) gene differ widely in survival suggesting other factors have a ...

The interaction of symptomatology (rigidity/chorea) in Huntington's disease (HD) with age of onset (AO) was examined using data from the Research Roster for Huntington's Disease Patients and Families.

Friedreich ataxia, an autosomal recessive neurodegenerative disease, is the most common of the inherited ataxias. The recent discovery of the gene that is mutated in this condition, FRDA , has led to ...

Background: Identification of hereditary predisposition to cancer has limited significance if not followed by efficient cancer prevention in the family. Probands are traditionally left to inform their ...
