This syndrome has characteristics of congenital thrombocytopenia associated with the presence of large platelets. To date less than 10 cases are reported. The syndrome is caused by mutations in the integrin, beta 3 ITGB3, tubulin, beta-1TUBB1 and actinin, alpha1 ACTN1 genes. These mutations lead to abnormal proplatelets and thrombocytopenia. Transmission is autosomal dominant. [from
