Treacher Collins Syndrome - GeneReviews® - NCBI Bookshelf
WebThis gene encodes a nucleolar protein with an LIS1 homology domain. The protein is involved in ribosomal DNA gene transcription through its interaction with upstream binding factor (UBF). Mutations in this gene have been associated with Treacher Collins syndrome, a disorder which includes abnormal craniofacial development. WebFamilial testing for Treacher Collins syndrome (TCS) depends on the pattern of inheritance in the family. About 60% of those with TCS are the first in their family to have this condition due to a new/sporadic (de novo) genetic change. In this case, the chance for the parents or siblings of the person with TCS to have a mutation would be low. electronic triggers for firearms
Inheritance: How is Treacher Collins syndrome inherited?
WebThe main gene that causes Treacher Collins syndrome (TCS) has been found to have many different changes that cause TCS. Most families have a different change than any of the other families who have TCS. A "variant" is another word for a change in a gene.
