Termination is the standard medical recommendation to pregnant parents when XXY chromosomes are identified at the fetus stage, in akaryotypetest. Yet, there is nothing inherently detrimental about being built with XXY chromosomes. XXY men can have the same strengths and attributes as XY men. XXY ...
Usually results from aberrant segregation of sex chromosomes in meiosis; maternal or paternal errors appear equally likely. • The phenotype appears to be associated with genes mapping to the long arm of the X chromosome. It appears that males with a smaller number of CAG repeats in the X‐...
Genetic analysis. Cytogenetic study by GTG banding of peripheral lymphocytes showed a XXY/XXXY/XXXXY mosaicism (data not shown). FISH analysis of 207 cellular nuclei, using probes for chromosomes X and Y, indicated a line proportion of 3% for 47,XXY, 36% for 48,XXXY and 61% for 49,XXX...

The syndrome is usually caused by the presenceof one additional X chromosome (47,XXY aneuploidy),however, rare syndrome variants with X and Y polysomy,mosaicisms and aberrant chromosomes have beenreported, including 46,XX, 48,XXXY, 48,XXYY, 49XXXXY,47,XXY/48,XXXY and 48,XXXY/49,XXXXY ...
