Marshall-Smith syndrome is a malformation syndrome characterized by advanced bone age, failure to thrive, respiratory problems, dysmorphic facial features, and variable mental retardation.[1][2] Less than 40 cases have been reported in the literature, mostly as single case reports or small series.[2] Early death is common due to respiratory complications.[3][4] The cause of this disease remains unknown, but its sporadic occurrence suggests a de novo (new) dominant mutation.[5] Aggressive management of the early respiratory and feeding problems may improve survival in individuals affected by this condition.[6][7]
