Fm. Mohammed et al., FAMILIAL PERICENTRIC-INVERSION OF CHROMOSOME 13,46,XX,INV(13)(P13Q11)- A NEW VARIANT, Annales de genetique, 36(3), 1993, pp. 181-185
A 10-year-old female with right oblique inguinal hernia was investigat
ed to exclude an XY karyotype. Chromosome analysis of peripheral blood
showed 46,XX,inv(13)(p13;q11). In vitro aneuploidy was observed in tw
o cells : a) 46,XX,inv(l3), inv(13); b) 47,XX, +inv(l3). Her father an
d three sisters were carriers for inv(l3). Herein the authors review b
riefly familial inv(l3)'s and report a new variant involving breakpoin
ts (pl3;q11).
