Abstract:
:An infant with features of trisomy 10p syndrome was found to have an abnormal chromosome 10: 46, XY, rec(10), dup p, inv(10) (p11q26) mat. The infant's mother was heterozygous for a pericentric inversion involving chromosome 10 (46, XX, inv (10) (p11q26). The infant's derivative chromosome was apparently produced by meiotic recombination between the inversion chromosome and its normal homologue.
