Abstract
Cerebral cavernous malformations are vascular lesions that usually involve brain micro-vessels. They can occur both in a sporadic form and familial one. Causes of familial forms are mutations at three loci: CCM1/KRIT1, CCM2/MGC4607, and CCM3/PDCD10. Here, we describe a novel CCM3 missense mutation (c.422T>G) detected in two Greek brothers showing multiple lesions at magnetic resonance imaging; to date, only the youngest is symptomatic. Bioinformatics tools showed this novel variant causes a loss of function in Pdcd10 protein due to its localization in the eighth helix and, particularly, affects Leu141, a highly conserved amino acid. Roles of Pdcd10 in angiogenesis regulation and its association with early development of cerebral cavernous malformations were also considered.
