The Clear SMA Types And Treatments

Type 4

Men, this is the one that gets adults! SMA type 4 starts in someone's late teens, but before they reach 20. The catch? Men, you're not always going to notice them until later in your 20s and 30s. Diagnosis for many, many men happens between age 35 and 40. Men, you don't get symptoms as a kid because of your genes! Anyone with this type has 4 or 6 copies of the SMN2 gene. This will make up for the mutations that happen with other types of SMA! So symptoms are delayed. They're milder too! Obviously, it means weakness in the legs, hips, arms, and shoulders. Just like the others! Men, some of you will be able to walk for short distances with a walking stick or other aid! Others? A wheelchair is going to be needed.
