The gene, known as lamin A (LMNA), makes a protein necessary for holding the center (nucleus) of a cell together. When this gene has a defect (mutation), an abnormal form of the lamin A protein called progerin is produced and makes cells unstable. This appears to lead to progeria's … A genetic disorder is a health problem caused by one or more abnormalities in the genome. It can be caused by a mutation in a single gene (monogenic) or multiple genes (polygenic) or by a chromosomal abnormality.
