Dilated cardiomyopathy in a 3-year-old girl with a terminal deletion, 46,XX,del(3)(q27-qter), of the long arm of chromosome 3.

Unlabelled: We report a case in which a 3-year-old girl with terminal deletion of the long arm of chromosome 3 had dilated cardiomyopathy, a complication that has not previously been reported in association with this chromosome abnormality. In addition to cardiomyopathy, she had intrauterine growth retardation, small eyes and mouth, a broad nose, thin lips, low-set ears, a short neck and overlapping second toes.

Conclusion: due to the paucity of reported cases of 3q deletion, and the clinical variability of such cases, identification of a distinct 3q phenotype (including cardiac complications) remains elusive.
