Katie was 5 months pregnant when she and her husband went in for a routine ultrasound. When the technician measured Claire, she found that her arms were a little shorter than they should be. They had a follow up appointment scheduled for four weeks later, thinking everything would be normal. At 6 months pregnant, they found out that Claire had a form of skeletal dysplasia, which they later found was Rhizomelic Chondrodysplasia Punctata or RCDP. This form of skeletal dysplasia is very rare and fatal.
