3:1 Meiotic disjunction in a mother with a balanced translocation, 46,XX,t(5,14)(p15;q13) resulting in tertiary trisomy and tertiary monosomy offspring

We describe the family of a balanced translocation carrier mother with the karyotype 46,XX,t(5,14)(p15,q13). In two of her five children 1:3 segregation occurred, resulting in del (14q) and dup (14q). The propositus with the dup (14q) has some of the typical manifestations of this syndrome and coloboma of the iris O.U.
