Skin and hair abnormalities of Cantu syndrome: A congenital hypertrichosis due to a genetic alteration mimicking the pharmacological effect of minoxidil

Kentaro Ohko et al. J Dermatol. 2020 Mar.

Abstract

Cantu syndrome is an autosomal dominant disorder, first described by Cantu in 1982, that is characterized by congenital hypertrichosis, characteristic facial anomalies and cardiomegaly. Recent investigations have revealed that this syndrome is caused by mutations of ABCC9, which encodes a regulatory subunit of SUR2, an adenosine triphosphate-mediated potassium channel opener, expressed not only in smooth muscle but also in hair follicles. However, the abnormalities of skin and hair in patients with Cantu syndrome have not been well explored. We herein report three Japanese patients with Cantu syndrome and describe their specific skin manifestations and alterations in the histopathology of their hair follicles and sebaceous glands. Similar alterations were shared among those three patients and may be related to the function of SUR2, namely the regulation of hair follicle growth, because SUR2 is a known pharmacological target of minoxidil.

Keywords: ABCC9; Cantu syndrome; hypertrichosis; minoxidil; sebaceous gland.
