Cat Eye Syndrome Genetics
Cat Eye Syndrome Genetics. It can affect the eyes, ears, kidneys and heart, and is a congenital disorder. Cat eye syndrome is a clinically recognizable congenital malformation syndrome consisting primarily of colobomas, anal anomalies, preauricular.

Its colloquial name is due to the fact that people who suffer from it have a very characteristic eye shape. In people with this condition, each cell has at least one small extra chromosome made up of genetic material from chromosome 22. Cat eye syndrome (ces) is a rare chromosomal disorder that may be evident at birth.
It Can Affect The Eyes, Ears, Kidneys And Heart, And Is A Congenital Disorder.
The disorder is characterized by intellectual disability and delayed development, small. Cat eye syndrome (ces) is a rare chromosomal disorder that may be evident at birth. Cat eye syndrome (ces) is characterized clinically by the combination of coloboma of the iris and anal atresia with fistula, downslanting palpebral fissures, preauricular tags and/or pits, frequent occurrence of heart and renal malformations,.
The Abnormality Is Located On Chromosome 22, And Its Presence Is Usually Only Detected When Doctors Notice The Telltale Symptoms.
In people with this condition, each cell has at least one small extra (duplicate) chromosome made up of genetic material from chromosome 22. Cat eye syndrome and genetics since cat eye syndrome isn't typically passed down, there's not a lot of concern when it comes to the genetics side of the disorder. Cat eye syndrome affects several parts of the body which involves the heart, ears, kidneys, and eyes.
Ces Is The Result Of A Genetic Defect In Chromosome 22, Which Causes An Extra Chromosome Fragment.
This syndrome causes a hole in the iris to appear and make a person’s eye look similar to a cat’s. Usually ces patients have a karyotype 47,xn,+inv dup(22)(q11.2),. Cat eye syndrome is a scarcely occurring genetic condition that may be present when people have additional copies of parts of the 22nd chromosome.
Symptoms Of Ces Are Typically Evident At Birth.
In people with this condition, each cell has at least one small extra chromosome made up of genetic material from chromosome 22. Despite the significant impact this disorder has on affected individuals, models for ces have not been produced due to the difficulty of effectively duplicating the corresponding chromosome region in an animal model. Cat eye syndrome is a clinically recognizable congenital malformation syndrome consisting primarily of colobomas, anal anomalies, preauricular anomalies, cardiac and renal defects, and mild to moderate mental retardation.
The Name “Cat Eye” Was Introduced Because Of Iris Colobomas Resembling The Pupils Of The Cat.
This extra genetic material leads to the characteristic signs and symptoms of cat eye syndrome. This kind of variance is also known for cat‐eye syndrome (ces) patients, presenting an ssmc derived from chromosome 22, first reported in 1965 (omim; Cat eye syndrome (ces), a human genetic disorder caused by the inverted duplication of a region on chromosome 22, has been known since the late 1890s.
