Trisomi är en typ av kromosomrubbning, som innebär att man har tre exemplar i stället för det normala två av någon kromosom i sina celler.Den vanligaste trisomin är den för kromosom 21, vilket ger upphov till Downs syndrom.

European Journal of Human Genetics (1998) 6, 432–438. In 1971, de Grouchy et al. first described trisomy 8 mosaicism which was further delineated by Fryns et al., Sanchez and Yunis, Schinzel, and Riccardi in 1977. Constitutional trisomy 8 mosaicism is an uncommon but well-defined clinical syndrome that presents with a variable phenotype ranging from minimal to severe A collection of disease information resources and questions answered by our Genetic and Rare Diseases Information Specialists for Mosaic trisomy 8.

Technique: Fluorescence in Complete trisomy 8 occurs in 0.8% of spontaneous pregnancy loss (miscarriage).

Trisomy 8 can be complete (which is usually fatal causing a miscarriage) or can be mosaicism which is less severe and may cause some development delay, decreased IQ, and other physical abnormalities. This can include short or tall stature, limited facial expressions with wide spaced eyes, a large forehead, and a broad upturned nose. trisomy 8 syndrome a syndrome associated with an extra chromosome 8, usually mosaic (trisomy 8/normal), characterized by mild to severe mental retardation, prominent forehead, deep-set eyes, thick lips, prominent ears, and camptodactyly (abnormally flexed fingers). Description. Collapse Section. Humans normally have 46 chromosomes in each cell, divided into 23 pairs.

+ + N2 - Trisomy 8 as the sole abnormality is the most common karyotypic finding in acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), occurring in approximately 5% and 10% of the cytogenetically abnormal cases, respectively. An 8-month-old infant with trisomy 8 mosaicism is described.

Trisomy 8 is the most frequent numerical aberration in acute myeloid leukemia (AML), occurring at a frequency of 10% to 15%.1 Recent reports have suggested that AML patients with trisomy 8 have poor outcomes and are not responsive to cytarabine-based therapy.2,3 Although some studies have reported that trisomy 8 confers an independent prognostic risk in AML,4 a German AML cooperative group study reported that prognosis in the presence of trisomy 8 appeared to be dependent on the other

A chromosomal abnormality consisting of the presence of a third copy of chromosome 8 in Full trisomy 8, which occurs when all of the body's cells contain an extra copy of chromosome 8, is not compatible with life. A similar but less severe condition called mosaic trisomy 8 occurs when only some of the body's cells have an extra copy of chromosome 8. Everyone with mosaic trisomy 8 can have a different set of symptoms because they may have a different number of trisomic cells, and these trisomic cells may be found in different parts of the body. Speak to a genetic counselor or a medical geneticist to learn more about mosaic trisomy 8.

Better leukemia-free survival with allogeneic than with autologous HCT in AML patients with isolated trisomy 8: a study from the ALWP of the EBMT. Baron, F.
