We report on a 46,XY female with pontocerebellar hypoplasia and intellectual disability. To our knowledge, this is the fourth reported patient with this constellation and further confirms a rare new syndrome. The condition is probably a single gene disorder with a currently unknown mode of inheritance. The causative gene is likely involved in the normal gonadal sex determination as well as the cerebral and cerebellar formation and function. © 2013 Wiley Periodicals, Inc.
