Endocrinological Abnormalities Are a Main Feature of 17p13.1 Microduplication Syndrome: A New Case and Literature Review.

ABSTRACT: To date, 5 cases of 17p13.1 microduplications have been described in the literature. Intellectual disability was reported as the core feature, together with minor facial dysmorphisms and obesity, but a characteristic phenotype for 17p13.1 microduplication has not been delineated. Here, we describe a patient with a 1.56-Mb de novo duplication in 17p13.1, affected by mild intellectual disability, facial dysmorphisms, obesity, and diabetes. By comparing the different phenotypes of currently described cases, we delineated the main clinical features of 17p13.1 microduplication syndrome. All patients described to date had variable facial dysmorphisms; therefore, it was difficult to define a common facial gestalt. Furthermore, we stress endocrinological abnormalities as important features and the need to monitor these over time.
