Brachydactyly type A (BDA) Brachydactyly type B (BDB) Brachydactyly type C (BDC) Brachydactyly type D (BDD) Brachydactyly type E (BDE) Hypertension and brachydactyly syndrome (HTNB)
Description
Brachydactyly (BD) comprises hereditary limb malformations characterized by apparent shortening of digits. Bone dysostosis is seen in middle phalanges in type A; distal phalanges in type B; distal phalanx of the thumb in type D; metacarpals in type E. Type C is characterized by shortening of multiple phalanges and hyperphalangy. BD is caused by improper development of the bones.

Title
PDE3A mutations cause autosomal dominant hypertension with brachydactyly.
Acromesomelic dysplasia (AMD) is a group of autosomal recessive form of skeletal disorders characterized by dwarfism associated with anomalies of middle and distal segments of the extremities. Mutations in four genes (GDF5, NPR2, BMPR1B, and PRKG2) have been reported to cause different forms of AMD.

Biallelic cGMP-dependent type II protein kinase gene (PRKG2) variants cause a novel acromesomelic dysplasia.
Proximal symphalangism is a condition characterized by variable fusion of the proximal interphalangeal joints. Multiple synostosis syndrome (SYNS) is a more severe form of proximal symphalangism with additional bone fusions involving carpal, tarsal, and other joints.
