Familial marker chromosome due to 3:1 Disjunction of t(9;15) in a grandparent

Familial marker chromosome due to 3:1 Disjunction of t(9;15) in a grandparent

An extra small chromosome detected in amniotic fluid was identified as the product of a translocation [46,XX,t(9;15)(p24;q11.2)]. This case is unusual in that individuals with the unbalanced karyotype resulting from a 3:1 disjunction are phenotypically normal.
