(1) Many metals, for example, have adverse effects on plants if they are concentrated to high levels; the result is plant deformities, dwarfism , or death of the plant.(2) The problem, according to Martin, is that while the body size of a large species shrinks considerably in cases of island dwarfism , brain size shrinks moderately.(3) There was no history of familial dwarfism or known exposure to teratogenic drugs.(4) Mutations in the transmembrane domain of FGFR3 cause the most common genetic form of dwarfism , achondroplasia.(5) The scientific point was that in the past 10 years, the mutations responsible for nearly all forms of dwarfism had been identified.
