Brachydactyly is an inherited condition, which makes genetics the main cause. If you have shortened fingers or toes, other members of your family most likely also have the condition. It is an autosomal dominant condition, which means you only need one parent with the gene to inherit the condition.View full answer

What causes clubbing of fingers and toes?
Clubbed fingers is a symptom of disease, often of the heart or lungs which cause chronically low blood levels of oxygen. Diseases which cause malabsorption, such as cystic fibrosis or celiac disease can also cause clubbing. Clubbing may result from chronic low blood-oxygen levels.
Although clubbing itself is harmless and doesn't require treatment, it is often associated with health conditions that can worsen without treatment.

Causes of Brachydactyly
Most types of brachydactyly are genetic, which means that they can be passed down in a family. It's a dominant genetic trait, so only one parent needs to have the condition for a child to inherit it.
Megan Fox's thumbs are genetic
Fox has a condition called brachydactyly. Brachydactyly is an inherited trait that causes the shortening of bones. In Fox's case, her “club thumbs,” as they are sometimes called, are medically referred to as brachydactyly type D, meaning the trait specifically affects her thumbs.
Basically, toe thumbs occur when the last bone on the thumb—or the distal phalanx—is congenitally shortened, says Badia. ... Badia says that, like many congenital differences, there is no clear cause for toe thumbs, adding, however, that there does seem to be a higher prevalence in certain populations.
The gene that controls the extendibility of the thumb is known as the "Bendy thumb gene." The bendy thumb gene comprises of multiple alleles in the chromosomes. One allele from the bendy thumb gene can produce a straight thumb and another allele may produce a hitchhiker's thumb.
Stub thumbs or brachymegalodactylism, a term coined by Hefner (i924), refers to the condition of having an abnormally or disproportionately short thumb on one or both hands. This anomaly has been recognized for many years and among palm readers and fortune tellers it has been called 'murderer's thumbs'.
It's not a perfect replacement. The great toe looks different than the thumb, and it functions in ways different than the thumb. And it's not just the hand that has to heal, the foot does too. “The worst part of it was taking the toe off,” Colello said, eight months after the procedure.
It could be a result of a genetic flaw in the right hand cells or the left hand cells. It could be a result of a flaw in the blood flow to the right or left hand, giving the right hand to little building materials or the left hand to much.
The various types of isolated brachydactyly are rare, except for types A3 and D. Brachydactyly can occur either as an isolated malformation or as a part of a complex malformation syndrome. To date, many different forms of brachydactyly have been identified. Some forms also result in short stature.
Most types are rare, except for A3 (BDA3, OMIM#112700) and D (BDD, OMIM#113200) that have a prevalence of around 2% . In this review, we focus on brachydactyly type E (BDE, OMIM#113300), which is rare and can be diagnosed as an isolated finding or as part of several genetic syndromes [1, 5, 6].
Type A1 brachydactyly can be caused by mutations in the Indian hedgehog gene (IHH) located on chromosome 2q35-36 .
