We prospectively studied @entity91 , regardless of neurologic status, by cranial computed tomography or psychometric testing in 56 @entity1 . None of the 27 @entity1 with simple @entity91 (single or multiple suture involvement) had evidence of @entity1276 on CT scan. Of the 24 @entity1 with simple @entity91 who underwent psychometric testing, 17 were of average intelligence; six were in the low average range. The single mentally retarded @entity1 had a history of severe perinatal @entity1763 . @entity1276 occurred more frequently (five of 23 cases) in @entity1 with @entity91 , including @entity8257 , @entity2168 , and kleeblattsch  @entity85 . More striking than @entity1276 , however, was the finding of dysmorphic @entity2554 in eight @entity1 , including the three @entity1 with @entity4886 and four with @entity2168 . Nineteen of the 25 @entity1 with @entity91 receiving psychometric testing were of normal intelligence. Four @entity1 with borderline normal intelligence had either @entity2554 . The two @entity1 with @entity1032 were sisters with @entity2168 whose family included @entity1032 individuals. This study indicates that the incidence of @entity1276 and @entity1032 in @entity91 is lower than reported previously.
