Medicine:CACNA1C-related disorders
From HandWiki
Short description: Genetic disorders
CACNA1C-related disorders are a group of rare diseases caused by variants in the CACNA1C gene, which encodes a subunit of the L-type voltage-dependent calcium channel. Genomic sequencing has linked a number of heterogenous phenotypes to pathogenic variants in the CACNA1C gene:[1]
- Timothy syndrome, which may or may not occur with syndactyly
- Short QT syndrome or Brugada syndrome
- Long QT syndrome or other arrhythmia without additional symptoms.[2]
CACNA1C-related disorders are inherited in an autosomal dominant manner.[2] Symptoms of CACNA1C-related disorders are primarily neurological[3] and may include developmental delay, autism or autistic features, and seizures.[1] Facial dysmorphism may also be present.[4]
