The 16p11. 2–p12. 2 duplication syndrome is a recurrent genomic disorder with a variable phenotype including developmental delay, dysmorphic features, mild to severe intellectual disability, autism, obsessive or stereotyped behaviour, short stature and anomalies of the hands and fingers.
16p13. 11 microduplication syndrome is a recently described syndrome associated with variable clinical features including behavioral abnormalities, developmental delay, congenital heart defects and skeletal anomalies.
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 duplication occurs on the long (q) arm of the chromosome at a position designated q29.
Rubinstein-Taybi syndrome (RTS) is a genetic disease. It involves broad thumbs and toes, short stature, distinctive facial features, and varying degrees of intellectual disability.
Microdeletion and microduplication syndromes are disorders caused by submicroscopic deletions or duplications of contiguous genes on particular parts of chromosomes.
Affected Populations Well over 200 individuals have been reported in the medical literature. It has been estimated that approximately 1-2% of unexplained cases of X-linked intellectual disability may be due to MECP2 duplication syndrome.
1 microdeletion syndrome is a rare chromosome disorder. Symptoms may include seizures, moderate to severe learning problems, speech delays, behavior problems, trouble sleeping, and developmental delays (learn to crawl, sit or walk later than other babies).
A microdeletion is an abnormality that occurs when a piece of a chromosome is missing.
One of the best-characterized recurrent inversions giving rise to disease causes hemophilia A, an X-linked disorder caused by mutations in the factor VIII gene [36]. A recurrent inversion has been found in approximately 43% of patients [37].
What causes triploidy? Triploidy is the result of an extra set of chromosomes. This can occur when two sperm fertilizing one normal egg or a diploid sperm fertilizes a normal egg. It can also occur when a normal sperm fertilizes an egg that has an extra set of chromosomes.
Other deletions of part of a chromosome 1 Q93.59 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. 2 The 2021 edition of ICD-10-CM Q93.59 became effective on October 1, 2020. 3 This is the American ICD-10-CM version of Q93.59 - other international versions of ICD-10 Q93.59 may differ.
The 2022 edition of ICD-10-CM Q93.59 became effective on October 1, 2021.
16p11.2 duplication is a chromosomal change in which a small amount of genetic material within chromosome 16 is abnormally copied (duplicated). This duplication occurs in the short (p) arm of chromosome 16 at a position known as 11.2. Signs and symptoms can vary widely among affected individuals. Some individuals have no symptoms while others may have features such as low weight; small head size; behavioral problems; features of autism spectrum disorder; developmental delay; intellectual disability; and speech and language delays. This condition can occur sporadically as a de novo mutation (by chance) or can be inherited in an autosomal dominant manner from a parent. [1] [2] [3] Treatment depends on signs and symptoms present in each individual.
The most common features include: [1] [2] Some people with a 16p11.2 duplication are born with birth defects such as heart defects, cleft lip and palate, and differences in urinary tract development.
Some people with a 16p11.2 duplication are born with birth defects such as heart defects , cleft lip and palate, and differences in urinary tract development. There does not appear to be a consistent pattern of birth defects found in ...

Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.
Other deletions of part of a chromosome 1 Q93.5 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail. 2 The 2021 edition of ICD-10-CM Q93.5 became effective on October 1, 2020. 3 This is the American ICD-10-CM version of Q93.5 - other international versions of ICD-10 Q93.5 may differ.
A genetic syndrome characterized by mental retardation, speech impairment, microcephaly, ataxia, and seizures. The majority of cases result from deletions on the long arm of chromosome 15.
The 2022 edition of ICD-10-CM Q93.5 became effective on October 1, 2021.
Listen. Chromosome 16p duplication is a chromosome abnormality that occurs when there is an extra copy of genetic material on the short arm (p) of chromosome 16. The severity of the condition and the signs and symptoms depend on the size and location of the duplication and which genes are involved. Features that often occur in people ...
Features that often occur in people with chromosome 16p duplication include developmental delay, intellectual disability, behavioral problems and distinctive facial features. Most cases are not inherited, but people can pass the duplication on to their children. [1] .
