Summaries for Brachydactyly, Type B1

About this section
NIH Rare Diseases:47 Brachydactyly type B is a very rare genetic condition characterized by disproportionately short fingers and toes. The ends of the second and fifth fingers are usually underdeveloped with complete absence of the fingernails. The thumb bones are always intact but are frequently flattened and/or split. The feet are usually similarly affected, but less severely. Other features that may be present include webbed fingers (syndactyly) and fusion of the joints (symphalangism) and bones in the hands and feet. Only a few cases have been reported in the literature. This condition is caused by mutations in the ROR2 gene. Most cases have been shown to be inherited in an autosomal dominant fashion. Last updated: 6/6/2011

MalaCards based summary: Brachydactyly, Type B1, also known as brachydactyly type b, is related to anonychia-onychodystrophy with brachydactyly type b and ectrodactyly and brachydactyly, combined b and e types, and has symptoms including abnormality of the metacarpal bones, anonychia and short toe. An important gene associated with Brachydactyly, Type B1 is ROR2 (Receptor Tyrosine Kinase Like Orphan Receptor 2), and among its related pathways is Cardiac Progenitor Differentiation. Affiliated tissues include bone, and related mouse phenotypes are hearing/vestibular/ear and limbs/digits/tail.

UniProtKB/Swiss-Prot:69 Brachydactyly B1: A form of brachydactyly. Brachydactyly defines a group of inherited malformations characterized by shortening of the digits due to abnormal development of the phalanges and/or the metacarpals. In brachydactyly type B1 the middle phalanges are short but in addition the terminal phalanges are rudimentary or absent. Both fingers and toes are affected. The thumbs and big toes are usually deformed. Symphalangism is also a feature.
