A. Paoloni-giacobino et al., Pure partial trisomy 5q33 -> 5q35 resulting from the adjacent-1 segregation of a paternal (5;14)(q33;p12) translocation, ANN GENET, 42(3), 1999, pp. 166-169
A 14-year-old male was referred for evaluation of mental retardation with s
hort stature and dysmorphic features. His karyotype was 46,XY,der(14)t(5;14
)(q33;p12)pat, resulting in a pure partial 5q33-q35 trisomy due to the adja
cent-1 segregation of a paternal balanced translocation. Paternal blood kar
yotype revealed a balanced translocation t(5;14)(q33;p12) retaining Ag-Nors
. To date, only two cases of pure partial 5q trisomies spanning this region
have been reported, Analysis of these cases and the one we report does not
allow the delineation of a specific phenotype.
