Hello Forum,

please have a look at this image

There are two proteins A and B in the right column.
Marker B is the protein´s length of healthy people.
But as you can see there are two different markers for this protein (the western Blot was made for one patient).

How can you explain the appearance of two different markers in one patient?

Can you explain with examples how changes of genes can lead to this result?

Can you explain with examples how changes of genes can lead to this result?

The answer to this question is a nonsense-mutation because of the substitution of one base-pair (exmaple 1). The second example is a nonsense-mutation because of insertion or deletion of base-pairs.

Do you have any further examples which explains this result?

How can you explain the appearance of two different markers in one patient?

The different genes express two different proteins. The "healthy" gene codes for the "healthy" protein and the other gene codes for the short protein. Both proteins are expressed in this patient.
Mutation is caused due to radioactive waves or it is inherited. It is possible that there is a co-dominant expression and, therefore, both proteins are expressed.

Do you have any other possibilities?

The markers above are related to the protein Enolase. Marker B is the Enolase and marker A is the mutated enzyme.

Maybe you have some more accurate possibilities considering the mutations and their causes which are related to this enzyme.
