chromosome 5 duplication

For most diseases, symptoms will vary from person to person. They can direct you to research, resources, and services. Chromosome 5q Duplication Syndrome is a chromosome abnormality that occurs when there is an extra copy of genetic material on the long arm (q) of chromosome 5 The severity of the condition and the signs and symptoms depend on the size and location of the duplication and which genes are involved 2003;23:81-82. The size of the inversion and its location often will determine the risk for unbalanced offspring. In some cases, the duplication may result from a balanced chromosomal rearrangement in one of the parents and in rare cases the translocation is a new event in the child (de-novo translocation). Chromosomal microarray analysis can more accurately identify the breakpoints involved in a trisomy 5p and will detect unbalanced but not balanced rearrangements. The symptoms and physical findings associated with trisomy 5p are variable and depend on the location and size of the duplicated segment. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. The severity of the condition and the signs and symptoms depend on the size and location of the duplication … Cervera M, et al. [2], In general, many affected infants and children with a 5p duplication have abnormalities that include low muscle tone (hypotonia); an unusually large head (macrocephaly), and additional abnormalities of the head and facial (craniofacial) area; long, slender fingers (arachnodactyly); developmental delay; and intellectual disability. These individuals have less variability since all of the material involved is from chromosome 5p. Am J Med Genet. Grosso S, et al. Duplication (5p13 leads to pter): prenatal diagnosis and review of the literature. Unique – Rare Chromosome Disorder Support Group. Complete trisomy 5p owing to de novo translocation t(5;22)(q11;p11) with isochromosome 5p associated with a familial pericentric inversion of chromosome 2, inv 2(p21q11). Individuals are noted to have a short neck. They carry the genetic characteristics of each individual. For the majority of the phenotypic features to be present, the duplication must include 5p10 to 5p13.1. Cytogenet Genome Res. It is generally difficult to say what the future will hold for affected individuals, because even when the chromosome abnormalities are similar the health problems can vary widely. Pairs of human chromosomes are numbered from 1 through 22, with an unequal 23rd pair of X and Y chromosomes for males and two X chromosomes for females. Am J Med Genet. This is a cause of some birth defects. 40MB duplication in chromosome band 5p13.1p15.33 with 800kb terminal deletion in a fetus with mild phenotypic features. This is the American ICD-10-CM version of Q92.5 - other international versions of ICD-10 Q92.5 may differ. The information in NORD’s Rare Disease Database is for educational purposes only and is not intended to replace the advice of a physician or other qualified medical professional. Prenat Diagn. The increase in respiratory infections is thought to be due to a molecule that helps protect the lining of the mouth and respiratory track from bacteria. Euro J Med Genet. The chin is set back (retrognathia) but in a few cases, in older individuals, the chin is prominent. 1983;20:394-396. Brimblecombe FS, et al. Duplication of chromosome is another type of chromosomal rearrangement. Periventricular heterotopia is a brain malformation caused by abnormal duplication of certain parts of chromosome 5. Parents are counseled regarding the risks of amniocentesis and then are asked if they consent to the procedure. While the features for trisomy 5p appear consistent, the diagnosis cannot be made on clinical features alone. Do you know of an organization? Multiple cases have been due to small supernumerary marker chromosomes comprised of all or a majority of material from the short arm of chromosome 5. Yasutomo K, et al. This CNV is inherited from a healthy mother. Do you have more information about symptoms of this disease? Four types of duplication: 1. Such treatment may require the coordinated efforts of a team of medical professionals who may need to systematically and comprehensively plan an affected child’s treatment. This region is said to have originated at Xq21.3 when a 3.5 Mb region of the X chromosome underwent duplication and transposition on the Y chromosome at Yp11.2 approximately 5… Even very small duplication in the 5p region have been implicated in both physical and neurodevelopmental abnormalities. Inclusion on this list is not an endorsement by GARD. Scott & White Medical Center-Temple Chromosome 5 duplication (q11-q22): Chromosome 5 duplication (q11-q22) is listed as a type of (or associated with) the following medical conditions in our database: Genetic conditions. The variability is due solely to the size and location of the duplication. Patients must rely on the personal and individualized medical advice of their qualified health care professionals before seeking any information related to their particular diagnosis, cure or treatment of a condition or disorder. CVS involves the removal of tissue samples from a portion of the placenta. Use the HPO ID to access more in-depth information about a symptom. Clinical Dysmorphology. Identifying genes on each chromosome is an active area of genetic research. Menendez I, et al. Translocations occur when a portion of one chromosome breaks off and switches places with another chromosome piece that has broken off. Partial trisomy of the pericentromeric region of chromosome 5 in a girl with Binder phenotype. Background: Supernumerary marker chromosomes derived from chromosome 5 (SMC5) and 5p13 duplication syndrome are rare disorders, and phenotypic descriptions of patients are necessary to better define genotype-phenotype correlations for accurate, comprehensive genetic counseling. Cells from the tissue are grown and cytogenetic or chromosomal microarray analysis performed. Section Chief, Cytogenetics Infants with the disorder may have a normal birth weight or intrauterine growth retardation (IUGR). Symptoms of Chromosome 5 duplication (q11-q22) (Dup (5)(q11-q22)) Some of the symptoms of Chromosome 5 duplication (q11-q22) incude: Psychomotor retardation; Musculoskeletal abnormalities; Facial … Chromosome 5 is one of the largest human chromosomes and contains numerous intrachromosomal duplications, yet it has one of the lowest gene densities. The HPO Sonography. J. Med Genet. Do you know of a review article? Early intervention is important to ensure that children with trisomy 5p reach their potential. Apgars at birth may be lower than the expected 9/10 and have been reported in the range of 5/6 most likely due to respiratory distress (trouble breathing) and low muscle tone (hypotonia). New York, NY: Oxford University Press; 2001. TEXTBOOKS Gorlin RJ, et al, eds. Trisomy of the short arm of chromosome 5p due to a de novo inversion and duplication (5)(p15.3p13.3). Since each abnormality is usually so rare, there are few cases to learn from, let alone conduct research. There may be a large tongue (macroglossia). Treatment may require an MRI or CT scan of the head to diagnose and possibly treat any excess fluid in the ventricles of the brain. Other findings may be present if there are monosomies (deletions) due to complex rearrangements or translocations involving other chromosomes and the short arm of chromosome 5p. This extra copy is known as a duplication. A geneticist aids in determining what specialists are needed, coordinates the care of the affected individual, and provides genetic counseling regarding risks for future pregnancies and risks for other family members Other professionals may include pediatricians for general health assessment; surgeons; cardiologists; cardiac surgeons; ophthalmologists; ear, nose and throat specialists, neurologists and/or other health care professionals. 3.7 Mb tandem microduplication in chromosome 5p13.1-p13.2 associated with developmental delay, macrocephaly, obesity, and lymphedema. 1999;87:6-11. This information comes from a database called the Human Phenotype Ontology The critical region for developmental delay and intellectual disability is thought to be the duplication of 5p14 to 5p15. Based upon the data for critical area, the gene NIPBL has been reported as possibly being the candidate gene for the syndrome. The presence of an additional chromosome segment, as compared to that normally present in a nucleus is known as Duplication. Vera-Carbonell, A, et al. A translocation may be suspected in individuals who have had multiple miscarriages. Supernumerary marker chromosomes derived from chromosome 5 (SMC5) and 5p13 duplication syndrome are rare disorders, and phenotypic descriptions of patients are necessary to better define genotype-phenotype correlations for accurate, comprehensive genetic counseling. All 5 duplications involved the NIPBL gene, 4 of which duplicated the entire gene; 4 of the duplications included part or all of the FLJ13231 (C5ORF42) gene. The disorder is characterized by … Each chromosome … Trisomy 5p. Characteristic physical features of the syndrome have been reported in individuals with complete duplications of 5p as well as those with various partial duplications and individuals who are mosaics. In the case of 5p duplication, where most of the material is derived from the short arm, the ring will include a very small area on the long arm that is near the centromere that does not contain genes with known clinical consequence. Characteristic physical features of 5p duplications have been reported in individuals with complete duplications of 5p as well as those with various partial duplications. 1982;12:43-49. (For further information on such disorders, choose the name of the specific chromosomal disorder in question or use “chromosome” as your search term in the Rare Disease Database.). Most physical features are due to a duplication of the bands 5p13.0 to 5p13.3. Clin Genet. Please note that NORD provides this information for the benefit of the rare disease community. Rethore MO, et al. Offspring produced from a parent with a balanced translocation may be balanced and thus have no phenotypic features since there is no duplication or be unbalanced.
