Nail-patella syndrome is a very rare genetic disorder that is also referred to as Iliac Horn Syndrome, Hereditary Onychoostedysplasia, Fong Disease or Turner-Kiser Syndrome.
The Nail-Patella syndrome is inherited via autosomal dominancy (see autosomal dominant) linked to aberrancy on human chromosome 9's q arm (q stands for longer arm), 9q34. This autosomal dominancy means that only a single copy, instead of both, is sufficient for disorder to be expressed in the offspring, meaning that the chances of getting the disorder is 50 %. The frequency of the occurence is 1/100.000. The disorder is linked to the ABO blood group locus.
