Investigating a Karyotype of 3q29 Microdeletion Syndrome. 3q29 microdeletion syndrome is a recurrent subtelomeric deletion syndrome with variable clinical manifestations including intellectual deficit and dysmorphic features.
It is also associated with a variety of other neurodevelopmental and neuropsychiatric outcomes including mild to moderate intellectual disability autism and anxiety.

56 rows 3q29 microdeletion syndrome is a rare chromosome disorder. Microdeletion and microduplication genetic syndromes are known to be a significant cause of developmental delay and dysmorphology. 3q29 microduplication syndrome also known as 3q29 duplication syndrome is a condition that results from the copying duplication of a small piece of chromosome 3 in each cell.
The clinical phenotype is variable despite an almost identical deletion size. The clinical phenotype is variable despite an almost identical deletion size. People with 3q29 deletion syndrome are missing a small part of a region on human chromosome 3 and people with 3q29 duplication syndrome have an extra part of their chromosome 3.
3q29 microdeletion syndrome also known as 3q29 deletion syndrome is a condition that results from the deletion of a small piece of chromosome 3 in each cell. We report the identification of six patients with 3q29 microdeletion syndrome. Heterogeneous clinical and neuropsychological features such as intellectual disability developmental and language delay hypotonia and to a lesser extent microcephaly that is present in about the half of the reported patients characterize the 3q29 microduplication syndrome with usually a milder phenotype compared with the corresponding 3q29 microdeletion syndrome.
Definition 3q29 microdeletion syndrome also known as 3q29 deletion syndrome is a condition that results from the deletion of a small piece of chromosome 3 in each cell. 2005 reported the identification of 6 patients with 3q29 microdeletion syndrome. A long and narrow face short philtrum and high.
3qter deletion Monosomy 3q29. Chromosome 3 is the largest metacentric chromosome comprises 200 million base pairs which represent 65 of total genomic content. There are currently no additional known synonyms for this rare genetic disease.
Chromosome 3 is associated with this condition. Long and narrow face short philtrum and high nasal bridge. Symptoms may include delay reaching some developmental milestones such as sitting walking or talking frequent ear and respiratory infections and a small head size microcephaly.
This syndrome was first described in 2005. Utilizing high-resolution chromosome analysis array CGH and SNP technologies we identified a novel genomic syndrome comprising of an interstitial duplication of approximately 161 Mb at the distal end of chromosome 3 band q29. 3q29 recurrent deletion is characterized by neurodevelopmental andor psychiatric manifestations including mild-to-moderate intellectual disability ID autism spectrum disorder ASD anxiety disorders attention-deficithyperactivity disorder ADHD executive function deficits graphomotor weakness and psychosisschizophrenia.
