Abstract

Partial trisomy 2p is typically associated with partial monosomy of another chromosomal segment and results from a balanced translocation in one of the parents. Inverted duplications with terminal deletions have been reported in an increasing number of chromosomes. Several cases initially interpreted as terminal duplications have instead been documented to represent inverted duplications with terminal deletions. Inv dup del(2p) has been reported in patients who manifest the clinical findings of trisomy 2p syndrome. Here we report on a 2-month-old girl with inv dup del(2p) and clinical manifestations that overlap those found commonly in partial 2p trisomy, as previously reported in the literature. Her clinical picture helps delineate the phenotype of 2p duplication disorders.
