3M syndrome (also spelt Three M syndrome and also known as dolicospondylic dysplasia, gloomy syndrome and le Merrer syndrome), is a very rare condition having only been reported in 32 patients.^[1][2] The name 3M originates from the initials of the 3 authors who made the first description.^[1] The major symptom caused by 3M is dwarfism, characteristic facies and radiological abnormalities among many others.^[3][1] There are no reports of individuals of this condition to show signs of mental retardation.^[1] 3M syndrome is thought to be inherited as an autosomal recessive genetic trait.^[4][5][1] Prenatal diagnosis is possible by ultrasonography. A treatment which possibly alleviates the dwarfism symptom is to use growth hormones to increase the height of the individual.^[1]
