Spontaneous splenic rupture in a patient with factor XIII deficiency and a novel mutation.

We report a novel mutation in factor XIIIA gene that caused severe congenital factor XIII deficiency in a 6 year and 8 month old male. The mutation is a GA deletion in the core domain leading to a premature stop at codon 502. The child had severe deficiency with two episodes of intracerebral hemorrhage. He also developed spontaneous splenic rupture, an unusual complication of this disorder. (c) 2007 Wiley-Liss, Inc.
