Monosomy and trisomy of 15q24→qter in a family with a translocation t(6;15)(P25;q24)

Abstract
A child with multiple anomalies, including growth retardation, a left-sided diaphragmatic hernia with lung hypoplasia, and cerebral malformations is described. Cytogenetic investigation demonstrated a deletion of the distal part of one chromosome 15, del(15)(q24qter), an aberration not previously described. Family studies revealed that the mother had a balanced translocation, t(6;15)(p25;q24). Two of her subsequent pregnancies resulted in abortions after prenatal diagnosis: one fetus was trisomic for 15q24 .fwdarw. qter, while the other had monosomy 15q24 .fwdarw. qter and a left-sided diaphragmatic hernia similar to the first child.
