Most of the cases Cutis Laxa is inherited. There generally
3 types of forms of genetic inheritance…
E Sex
Linked
E Autosomal
Dominant
E Autosomal
Recessive
The Autosomal Recessive form is the most common
& severe.
 
| 
   
Sex-linked 
 | 
  
   
The defective/mutated gene is carried on one of the sex
  chromosomes, in this case it is located on the X chromosome 
 | 
 
| 
   
Autosomal Dominant 
 | 
  
   
Only one copy of the defective/mutated gene is enough to cause
  CL. A child has a 50% chance of inheriting the gene from either parent. 
 | 
 
| 
   
Autosomal Recessive 
 | 
  
   
In this type the affected child must inherit two copies of the
  defective/mutated gene from both of its parent. The chance of transmitting an
  autosomal recessive disease is 25% for each pregnancy.
