The Roberts syndrome.Birth Defects Orig Artic Ser. 1974; 10(5):87-95.BD
The Roberts syndrome appears to follow an autosomal recessive mode of inheritance. The cause of the abnormalities probably exerts its effect prior to the seventh week of gestation and only on a few organ systems undergoing development during this time. The peculiar morphologic features of metaphase chromosomes of the one individual who has been studied extensively are unexplained.
