Recombinant chromosome 18 resulting from a maternal pericentric inversion.
We report on a newborn girl with duplication of 18q12.2-->18qter and deficiency of 18p11.2-->18pter which resulted from meiotic recombination of the maternal pericentric inversion, inv(18)(p11.2q12.2). Her clinical manifestations were compatible with those of partial trisomy 18q syndrome. We review the previously reported 9 cases in 8 families of rec(18) resulting from recombination of a parental pericentric inversion.
