Brachydactyly type B (BDB) is characterized by terminal deficiency of fingers and toes.
Etiology
BDB is caused by
heterozygous truncating mutations in the receptor tyrosine kinase-like orphan receptor 2 (ROR2) in the majority of patients
point mutations in the bone morphogenetic protein antagonist NOGGIN (#17668388#)
