GENETIC DISORDER:
PSEUDOACHONDROPLASIA
Frequently Asked Questions
01
How is Pseudoachondroplasia different from Achondroplasia?
Pseudoachondroplasia affects the joint cartilage as well as the growth of cartilage, while achondroplasia just affects the growth of cartilage. Due to the fact that pseudochondroplasia affects the joints many cases have additional derformations in the hip, ankles, and knees. While achondroplasia mainly affects the knees. Therefore they are thought of as different disorders.
02
What is the average height of a male and female living with Pseudoachondroplasia?
The average male height is 3 feet 11 inches. The average female is 3 feet 9 inches.
03
Does Pseudoachondroplasia occur more in males or females?
Pseudoachondroplasia occurs equally in males and females. However it is incredibly rare and it is estimated to occur in 1out of 30,000 people.
04
Can short-statured couples become parents? Of children with dwarfism? Of average-size children?
Yes. The odds vary with diagnosis, but a person with achondroplasia has one dwarfism gene and one "average-size" gene. If both parents have achondroplasia, there is a 25 percent chance their child will inherit the non-dwarfism gene from each parent and thus be average-size. There's a 50 percent chance the child will inherit one dwarfism gene and one non-dwarfism gene and thus have achondroplasia, just like her or his parents. And there is a 25 percent chance the child will inherit both dwarfism genes, a condition known a double-dominant syndrome, and which invariably ends in death at birth or shortly thereafter.
05
Is Pseudoachondroplasia more prevalent in a certain ethnicity?
They have not found that it occurs more frequently in one ethnicity over another.
