An inherited human disorder, familial dysautonomia, results from a nucleotide mutation in the gene IKAP that is expressed in the nervous system
The decreased IKAP protein leads to abnormal development, and the resulting disease is usually fatal by age 30. The nucleotide change alters splicing. If this change affects only the nervous system and not the immune system, in which the gene is also expressed, what feature must be found in this gene?
