title: Mental retardation and Y/8 translocation [karyotype: 46,XY, t(Y;8)(q12;q24)] in father and son.
abstract: In the present report we describe a 98/12-year-old male with Noonan phenotype, moderate mental retardation and 46,XY, der(8), t(Y;8)(q12;q24) karyotype. Further examination of the family revealed that the boy inherited the Noonan features from his mother and the Y/8 translocation from his moderately mentally handicapped father.
