a comic about a doctor explaining DMD to a patient
Doctor, my son cannot seem to walk anymore, what could he have?
It seems that your son has DMD, it usually affects younger males
Could you please explain what DMD is?
Of course, your son for example has a symptom of DMD, the inability to walk or run, other symptoms may include muscle weakness and trouble getting up especially when they are toddlers
Males are the ones mostly affected. Those who have DMD lack a protein called dystorphin this is because it is inherited from mothers gene mutation giving the son the DMD
Then genetic mutations causes muscular dystrophy because they temper with the muscle proteins. Muscle proteins are required to make and maintain healthy muscles. The cause a mutation on duchenne because it has genes missing or that don't go together. This error in genetic instructions makes it impossible for the cells to make dystophin so the muscles can work properly. We need muscles and heart muscles in order to move which contain protein. Since the protein cells can't make dystrophin, the muscles are substituted with fat and tissue.
Also transcription, which is the process in which DNA is being copied to mRNA that carries information needed for protein. Then the mRNA that formed in transcription gets transported out of the nucleus into the cytoplasm then to the ribosome. Then mRNA directs protein synthesis with the help of tRNA, making it the process of translation. During this complete process the nucleotides can get mutated, causing the mutations in DMD.
In order for you son to live a long life I suggest you take him to some therapy sessions that include walking and swimming. Wheelchairs and walkers can help maintain mobility and getting some braces to provide support for weakened muscles can help.
