Eyelid myxoma in Carney complex without PRKAR1A allelic loss

Am J Med Genet A. 2004 Nov 1;130A(4):395-7. doi: 10.1002/ajmg.a.30279.

Abstract

Eyelid nodules were investigated in a patient with Carney complex who was heterozygous for the most commonly known PRKAR1A-inactivating mutation, c.578delTG. Immunohistochemical studies confirmed the diagnosis of myxoma. Loss of heterozygosity was not present, suggesting that haploinsufficiency alone was responsible for tumorigenesis of this eyelid lesion.
