What is treacher collins syndrome caused by?

What is treacher collins syndrome caused by? Mutations in the TCOF1, POLR1C, or POLR1D gene can cause Treacher Collins syndrome. TCOF1 gene mutations are the most common cause of the disorder, accounting for 81 to 93 percent of all cases. POLR1C and POLR1D gene mutations cause an additional 2 percent of cases.

Why does Treacher Collins syndrome happen? Genes are passed from generation to generation. Genes occur in pairs, and everyone has thousands of different gene pairs. Treacher Collins Syndrome is believed to be caused by a change in the gene on chromosome 5, which affects facial development. About 40% of the time, one parent has Treacher Collins Syndrome.

What causes Treacher Collins syndrome and what are the odds of having it? A change in the gene TCOF1 causes up to 93 per cent of cases of Treacher Collins syndrome. This gene, located on chromosome 5, is responsible for facial development. In about half of all cases, TCOF1 spontaneously changes at conception but what triggers the gene change is unknown.

How is Treacher Collins syndrome transmitted? TCOF1 is an autosomal dominant gene. This means that only one copy of the abnormal gene is needed to cause the disease. It can be inherited from either parent or the result of a new mutation. If you’re an adult with TCS, you have a 50 percent chance of passing the gene to each child you bear.
