IVIC syndrome: report of a second family.

The IVIC syndrome derives its name from the Instituto Venezolano de Investigaciones Cientìficas, where it was described by Arias et al. [Am J Med Genet 6:25-59, 1980]. We report on several individuals in a family with the IVIC syndrome, the second described in the literature. In this family there are 3 affected individuals in 2 generations. This observation shows that the IVIC syndrome is not a private syndrome, and confirms that it is due to an autosomal dominant mutation.
