Chromosome 22q11 deletion presenting as the Potter sequence.

Abstract

A female fetus with the Potter sequence, caused by unilateral renal agenesis and contralateral multicystic renal dysplasia, was found to have a submicroscopic deletion in chromosome 22q11. The only associated anomaly was agenesis of the uterus and oviducts (Von Mayer-Rokitansky-Küster anomaly). The deletion was inherited from the father, who presented the typical velocardiofacial syndrome phenotype, but no urological anomalies. This observation further extends the clinical spectrum associated with a deletion in 22q11.
