While there is clinical overlap with the unrelated Cornelia de Lange syndrome (CDLS), there are distinguishing features and molecular etiologies. Most cases of 3q duplication appear to be the result of an unbalanced translocation or inversion and therefore accompanied by additional cytogenetic anomalies. Consequently, pure duplications of 3q are very rare;we are aware of only 12 such cases that have been reported previously. Here, we present a new case of pure, partial 3q duplication in a 3-month-old female who displayed a number of clinical signs consistent with previously reported phenotypes and the additional novel finding of a vascular ring.展开更多

The hemodynamic changes known to occur during pregnancy can exacerbate heart failure and arrhythmias in women with HCM. We present a 30-year-old woman with HCM to illustrate the benefits of multidisciplinary team management of severe left ventricular outflow tract obstruction (peak gradient >100 mmHg) for optimal maternal and fetal outcomes.展开更多
