Constitutional Karyotype in Retinoblastoma Case Report and Review of Literature

Abstract
High resolution karyotype was performed in 13 retinoblastoma patients. A mosaic pattern for del(13)(q14.1; q14.3) was found in a girl with sporadic bilateral retinoblastoma and mid-face dysmorphism. In addition, 162 cases of 13q aberrations were reviewed, including 140 retinoblastoma patients and 22 non-penetrance 13q14 deletions. Some epidemiological and genetic involvements are discussed.
