Answer:
Indivisuals with producing an abnormal form of extracellular protein fibrillin are suffering from Marfan syndrome ehich is caused by genetic mutation in the FBN1 gene.
Explanation:
Gene mutations in FBN1 gene results in the production of an abnormal extracellular matrix fibrillin-1 protein that cannot function properly. These gene mutations basically reduce the amount of fibrillin-1 produced by the cell, alter the structure of fibrillin-1, or causes the impairment of the transport of fibrillin-1 out of the cell.
As a result, protein is poorly incorporated into extracellular matrix. Hence, indivisuals with Marfan syndrome present following symptoms
