Abstract: Carney complex is a syndrome that may include cardiac and mucocutaneous myxomas, spotting skin pigmentation, and endocrine
lesions. Many patients with Carney complex have been shown to have a stop codon mutation in the PRKAR1A gene in the 17q22-24 region.
Here we present the case of a 57 year-old man with multiple skin lesions and cardiac myxomas. Histology of the skin lesions showed
lentigenous melanocytic hyperplasia and cutaneous myxomas, confirming the diagnosis of Carney complex. Lesional and control normal
tissue from the patient were identified and sequenced for the PRKAR1A gene. A germline missense mutation was identified at exon 1A. This
is the first report of this mutation, and one of the few reported missense mutation associated with Carney complex. This finding strengthens
the argument that there are alternative ways in which the protein kinase A 1-alpha subunit plays a role in tumorigenesis. (IJCEP1003009).
