Ring chromosome 17 is caused by genetic mutations, also known as pathogenic variants. Genetic mutations can be hereditary, when parents pass them down to their children, or they may occur randomly when cells are dividing.

Ring chromosome 17 syndrome is a rare chromosomal anomaly syndrome, resulting from partial deletion of chromosome 17, characterized by highly variable manifestations, ranging from a severe phenotype which presents with lissencephaly and severe intellectual disability to a milder phenotype that includes short stature, microcephaly, intellectual ...

Ring chromosome 17 occurs when a small amount of genetic material is lost from the ends of chromosome 17, and the chromosome bends to form a closed ring instead of it’s usual bar like structure. Children with ring chromosome 17 that does not involve the MDCR Only thirteen people have been reported in the medical

Nov 8, 2024 · The ring chromosome 17 phenotypic features range from the Miller–Dieker syndrome characterized by deletion of the PAFAH1B1 gene, lissencephaly, hypotonia, dysphagia, café au lait spots, and severe intellectual disability, to a milder phenotype characterized by microcephaly, seizures, delayed development, minor facial dysmorphic features ...

A rare chromosomal anomaly characterized by highly variable manifestations, ranging from a severe phenotype which presents with lissencephaly and severe intellectual disability to a milder phenotype that includes short stature, microcephaly, intellectual disability, seizures (that may be pharmacoresistant), café-au-lait spots, retinal flecks and...

A rare chromosomal anomaly syndrome resulting from partial deletion of chromosome 17.

Ring chromosome 17 (RC17) that replaces a normal chromosome 17 homologue is extremely rare, and only about 20 RC17 cases were reported in literature. RC17 is usually associated with deletion of the terminal regions of chromosome 17.

Ring chromosome 17 syndrome is a rare chromosomal anomaly characterized by highly variable manifestations, ranging from severe lissencephaly and intellectual disability to milder symptoms such as short stature, microcephaly, seizures, café …
