ICD-10: Q87. Apert syndrome (acrocephalosyndactyly type I, MIM #101200) is an autosomal dominant disorder that occurs in 6 to 15. 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. R 2 gene. Keywords: Apert syndrome, Genetic disorder, Craniosynostosis, FGFR2. Associate Professor in Medical Genetics, The University Apert syndrome can be passed down through families (inherited) as an autosomal dominant trait. Apert syndrome is caused by mutations in the FGFR2 gene, located on chromosome 10. Nearly all cases of this condition result from new (de novo) mutations in the gene that occur during the formation of reproductive cells (eggs or sperm) in an affected individual's parent or in early embryonic development. It is a rare autosomal dominant disease with an incidence of around 1 per 160 000 live births. Apert Syndrome is the result of a genetic change (mutation) in a gene called FGFR2 – “fibroblast growth factor receptor 2” – on chromosome 10. This one tiny change in the FGFR2 gene results in the physical features of Apert Syndrome. Areas of a child’s body that lead to an Apert syndrome diagnosis include the skull (the point at the top of the head), face (bones forming in irregular places), feet and hands (fingers and toes connected or Apert syndrome is characterized by fusion of the skull bones too early during development (craniosynostosis) and webbing of fingers and toes (syndactyly). This syndrome was first described by Eugene Apert in 1906. " Apert syndrome, Pfeiffer syndrome, Crouzon syndrome, and Antley-Bixler syndrome are related to mutations in FGFR family (especially in FGFR2), and mutations in FGFRs can be overlapped between different syndromes. This condition is closely linked with Oct 18, 2023 · 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. Suture progenitor cells with fibroblast growth factor receptors (FGFR2) that have undergone a mutation cannot transduce signals from extracellular fibroblast growth factors (FGFs). At least ten mutations in the FGFR2 gene have been found to cause Apert syndrome. [3,35] Apert syndrome is an autosomal disorder caused by mutations of the fibroblast growth factor receptor 2 gene (FGFR2) on chromosome 10q. The incidence of AS increases with advanced paternal age and is believed to result from mutations arising in the male germ cells that confer a selective survival advantage on sperm cells [].

Fullerton Genetics Center (2007 Feb 13, 2018 · Apert syndrome is a rare genetic disorder that causes a fetus’ facial and skull bones to fuse together too early in its development. Apert syndrome is characterized by craniosynostosis, a condition in which the fibrous joints (sutures) between bones of the skull close prematurely. Most cases are sporadic. Apert syndrome is a genetic disease in which the seams between the skull bones close earlier than normal. However, most individuals with Apert syndrome have the disorder as the result of a de novo FGFR2 pathogenic variant. 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. Activated Apert Syndrome was first described by the French pediatrician Eugene Apert in 1906. We do not yet fully understand what causes this mutation. 3 Apert Syndrome is rarely reported from India. However, this entire group has many overlapping features making classification on clinical grounds alone difficult.
