Apert syndrome chromosome Apert syndrome is caused by 1 of 2 possible mutations on chromosome 10. However, this entire group has many overlapping features making classification on clinical grounds alone difficult. Genes Involved. This disorder is caused by genetic mutations in the fibroblast growth factor receptor-2 (FGFR2), a chromosome 10 gene responsible for bone development. People with Apert syndrome can have distinctive malformations of the skull, face, hands, and feet. This gene provides instructions for making a protein called fibroblast growth factor receptor 2 (FGFR2). In healthy parents of an affected child, the recurrence risk in their children is low, but in affected patients, the risk of transmitting the disease to their offspring is 50%. Apert syndrome (AS), also known as type I acrocephalosyndactyly, is a rare congenital condition characterized by craniosynostosis resulting from missense mutations in the fibroblast growth factor receptor 2 (FGFR2) gene.

Most Apert Syndrome cases occur sporadically as a result of a new mutation (instead of being passed A number sign (#) is used with this entry because Apert syndrome is caused by heterozygous mutation in the FGFR2 gene on chromosome 10q26. [15] [16] Apert syndrome is an autosomal dominant disorder; approximately two-thirds of the cases are due to a C to G mutation at the position 755 in the FGFR2 gene, which Apert syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. As well as the skull and face, the hands and feet are also affected. 1. When you have Apert syndrome, you have a 1 in 2 (50%) chance of passing this condition to your child. Apert syndrome is characterized by fusion of the skull bones too early during development (craniosynostosis) and webbing of fingers and toes (syndactyly). Apert Syndrome is the result of a genetic change (mutation) in a gene called FGFR2 – “fibroblast growth factor receptor 2” – on chromosome 10.

However, most individuals with Apert syndrome have the disorder as the result of a de novo FGFR2 pathogenic variant. Suture progenitor cells with mutated FGFR-2 cannot transduce signals from extracellular FGF, as a result they do not produce the fibrous material required for normal calvarial sutures. Apert syndrome is a rare condition where your baby is born with physical abnormalities because joints in their skull close too early. Activated Apert Syndrome was first described by the French pediatrician Eugene Apert in 1906. 000 births.
