A comparison of the above-mentioned frequencies with those reported in our M7 series shows that, unlike in other AMLs, trisomy 8 was not predominant in M7 and that trisomies of chromosomes 19 and 21 were the most frequent gains. PMID 8194050 : Chromosome 19 abnormalities are commonly seen in AML, M7. The term "mosaic" indicates that some cells contain the extra chromosome 14, whereas others have the normal chromosomal pair.

One series is composed of de novo AMLs (n = 1045 cases) and another series includes only AMLs with complex karyotypes (200 AMLs with at least 3 unrelated abnormalities) where M7 represented 1% and 2% of cases, respectively, in these 2 series. "Full trisomy", also called "primary trisomy", means that an entire extra chromosome has been copied. (NCI Thesaurus).

Because trisomy 18 causes such serious physical defects, many babies with the condition don't survive to birth. What does Trisomy 19 mean? translocation.
Chromosome 19 spans more than 58.6 million base pairs, the building material of DNA. A chromosomal abnormality consisting of the presence of one chromosome in addition to the normal diploid number. The larger study by Dastugue et al identified an approximately 20% incidence of chromosome 19 abnormalities with trisomy 19 occurring in 8 (16%) of 50 patients lacking the Philadelphia chromosome. Having a child with trisomy 18 can sometimes be emotionally overwhelming, and it's important for parents to get support during this difficult time.
