We report a male infant with an association of hypothyroidism and unusual facies, including blepharophimosis, which is similar to the dysmorphic features observed in the condition first described by Young and Simpson [(1987) J Med Genet 24:715-7161. On the other hand, the patient also shares many features with those reported as having Ohdo blepharophimosis syndrome [Ohdo et al, (1986) J Med Genet 23:242-244]. Previous case reports are reviewed and difficulties concerning the differential diagnosis of these conditions are discussed.9199-204
