This could include, phalanges, metacarpals, metatarsals, carpals, and tarsals. Symptoms of isolated brachydactyly include shorter bones in the hands and feet. However exceptions could exist due to antiepileptic medicines taken during pregnancy or low blood flow to the extremities during infancy. Generally, brachydactyly is inherited through an autosomal dominant trait (The exact gene may differ see "Types" table for specific genes). Both are expressed in the same units (centimeters, for example) and are measured in an open hand from the fingertip to the principal creases where the finger joins the palm and where the palm joins the wrist. In clinical genetics, the most commonly used index of digit length is the dimensionless ratio of the length of the third (middle) finger to the hand length. Nomograms for normal values of finger length as a ratio to other body measurements have been published. Brachydactyly may also be a signal that one is at risk for congenital heart disease due to the association between congenital heart disease and carpenter's syndrome and the link between carpenter's syndrome and brachydactyly
It most often occurs as an isolated dysmelia, but can also occur with other anomalies as part of many congenital syndromes. Brachydactyly is an inherited, dominant trait. The shortness is relative to the length of other long bones and other parts of the body.

Brachydactyly ( Greek βραχύς = "short" plus δάκτυλος = "finger"), is a medical term which literally means "short finger".
