SNOMED CT Concept\Clinical finding (finding)\...

\Viscus structure finding (finding)\Cardiac finding\Heart disease\A disorder in which there is abnormal electrical activity in the heart.\A disorder in which there is abnormal electrical activity in the heart associated with a genetic disorder.\A rare, multiple congenital anomalies syndrome with cardiac involvement as a major feature characterized by QT prolongation, congenital heart defects, syndactyly, facial dysmorphism and neurodevelopmental features. There are three clinical phenotypes recognized, the classical types that present with a prolonged QT interval and either with (TS1) or without (TS2) cutaneous syndactyly of fingers and toes.

Timothy syndrome is a multi-system disorder with characteristics of cardiac, hand, facial and neurodevelopmental features that include QT prolongation, webbed fingers and toes, flattened nasal bridge, low-set ears, small upper jaw, thin upper lip, and characteristic features of autism or autistic spectrum disorders. Timothy syndrome is caused by mutations in the CACNA1C gene. It is inherited as autosomal dominant trait.

Timothy syndrome is a multi-system disorder with characteristics of cardiac, hand, facial and neurodevelopmental features that include QT prolongation, webbed fingers and toes, flattened nasal bridge, low-set ears, small upper jaw, thin upper lip, and characteristic features of autism or autistic spectrum disorders. Timothy syndrome is caused by mutations in the CACNA1C gene. It is inherited as autosomal dominant trait. Researchers have identified two forms of Timothy syndrome. Type 1, which is also known as the classic type, includes all of the characteristic features described above. Type 2, or the atypical type, causes a more severe form of long QT syndrome and a greater risk of arrhythmia and sudden death. Unlike the classic type, the atypical type does not appear to cause webbing of the fingers or toes.
