Dwarfism

Dwarfism

Dwarfism. Can be caused by over 300 different things! A form of dwarfism called Achondroplasia is caused by a mutation to a gene (FGFR3) that regulates bone growth. The mutation makes the FGFR3 gene too aggressive, which stops cartilage being turned to bone so limbs don’t grow properly.
