TCEB3
Tceb3 Gene: An Enigma in Human Disease
Description
The Tceb3 gene, located on chromosome 14q32.33, plays a crucial role in cellular processes and human health. It encodes the tubulin epsilon chain 3 (TUBB3) protein, a key component of microtubules, the cytoskeletal structures responsible for maintaining cell shape, dividing cells, and transporting intracellular cargo.
Associated Diseases
Mutations in the Tceb3 gene have been linked to a range of human disorders, including:
- Microcephaly: A condition characterized by an abnormally small head circumference at birth, often associated with intellectual disability and developmental delays.
- Lissencephaly: A rare brain malformation where the outer surface of the cerebral hemispheres is smooth and lacks the normal folds and grooves.
- Cornelia de Lange syndrome: A genetic disorder characterized by distinctive facial features, growth retardation, intellectual disability, and limb abnormalities.
- Microdeletion 14q32: A genetic deletion syndrome involving the Tceb3 gene region, causing a spectrum of developmental and cognitive impairments.
Did you Know ?
Approximately 1 in 10,000 newborns worldwide is affected by microcephaly, making it one of the most common birth defects. Mutations in the Tceb3 gene are responsible for a significant proportion of these cases.
