It's a genetic disease

Yes , genetic disease either by the mutation or deletion of exon 7

The cause is the lack of the gene SMN

The parents have two genes each,a parent may have
-two genes, smn1 (a parent also normal for the event following)
Or
-a gene smn1 good and a smn1 gene mutant(in spite of a mutant gene that parent has no problem whatsoever,the smn1 gene that works is sufficient for the proper functioning of the entire body,but as he deals rather of the muscles,it is more logical to say that it is sufficient for the proper functioning of muscles)
Or
-two genes in mutant (in the case where the parent is suffering from spinal muscular atrophy)
Each parent gives a gene smn1 has her child,I say one,it is not enough that a person with this disease "that we call a reaches to shorten" have a child with a person with two genes, smn1 good for a child to be sick,on the contrary, in this case, the son will not be reached,if it is not clear I recapitule :
-A parent with a mutant gene on the two who has a child with a parent who also has a mutant gene as 2 in 4 chance of having a child(I had no luck :P)
-if a parent has 2 good genes and that he has a child with a parent who has 2 bad genes 0 in 4 chance of having a child
-if a parent has 2 bad gene and he has a child with a parent that has a bad gene, a 3 in 4 chance of having a child(it is hot)
-two genes, smn1 (a parent also normal for the event following)
