Hypertension in Potocki-Shaffer syndrome: A case report.

Potocki-Shaffer syndrome (PSS) is a rare contiguous gene deletion syndrome caused by heterozygous deletion of 11p11.2p12. Typical features described in patients with PSS include developmental delay, intellectual disability, multiple cartilaginous exostoses, biparietal foramina, craniofacial abnormalities, and genitourinary anomalies. While hypertension has been noted in three patients with PSS, it has not been described in most patients with this syndrome. This report details the evaluation and treatment of a teenager with PSS who presented on several occasions during childhood with elevated blood pressure measurements. The renin level was elevated, likely indicating a secondary cause for the HTN. The patient's BP responded to monotherapy with Angiotensin Converting Enzyme Inhibitor (ACEI).
