I have this so called "clubbed thumbs"also known as brachydactyly.
It is of D-type.
I searched for it on internet and found that it is a dominant inherited disease.
But to my surprise,none of my family members have such thumbs.Not even my great grandfather/mother had this type of thumbs.
If it is a dominant trait then why didn't it show in any other family person. Is it that I have had any mutation in my genes?
