Your Question

I have Beals syndrome (also known as congenital contractural arachnodactyly). I am a 19-year-old female and I was wondering how tall I would be because of this condition? The symptom is having a tall stature, but how tall? I'm 5'3 right now.

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

What is congenital contractural arachnodactyly?

Congenital contractural arachnodactyly (CCA) is a genetic disorder that is typically characterized by tall height; skinny, long limbs; long, skinny fingers and toes (arachnodactyly); multiple joint deformities present at birth (congenital contractures), usually of the elbows, knees, hips, fingers and ankles; "crumpled"-looking ears, and curvature of the spine (kyphoscoliosis). Other features might also be present and vary from person to person. CCA is caused by mutations in a gene called FBN2 gene and is inherited in an autosomal dominant pattern.[1][2] CCA shares similiar signs and symptoms to Marfan syndrome; however, Marfan syndrome is not caused by mutations in the FBN2 gene.

How tall will I be if I have congenital contractural arachnodactyly?

Because many factors influence a person's height, we cannot comment on how tall you will be. We searched the medical literature to learn more about how a person's height might be affected by CCA, and we found that limited information exist regarding this topic. An article by Callewaert et al. (2009) states that patients tend to be tall (>90th percentile) from birth onward, in the absence of scoliosis.[3] However, it is important to note that symptoms vary from person to person; therefore, not all affected people are taller than other people in their family.
