symptoms Infant
  • Can have a breathing difficulty
  • Difficulty feeding, food may go down windpipe instead of stomach
  • Floppy infant, poor muscle tone
  • Lack of head control
  • Little movements
symptoms child
Symptoms child
  • Much less symptoms then infant
  • A increase in severe respiratory infections, frequently
  • Nasal speech
  • Your posture begins to get worse
4 types
4 types
  • SMA type I- infants born with very little muscle tone, very weak and will have feeding and breathing problems
  • SMA type II- symptoms don’t start to appear until 6 months to 2 years
  • SMA type III- mild disease, starts in childhood/adolescence
  • SMA type IV- even milder, weakness starts in adulthood
prevalence
Prevalence
  • 4 in every 100,000 people have it, 1 in every 25,000
  • 1 out of every 40 people are genetic carriers of the disease
  • When both parents have gene 1 of every 4 kids get it
  • You should check with your doctor before having kids if you have the gene
causes transmitted
Causes/transmitted
  • Most of the time to be affected the person has to get the defective gene from both of their parents autosomal recessive genetic disease
  • Missing or mutated gene SMN
  • Produces protein
  • Attacks nerve cells in spinal cord
treatments
Treatments
  • No treatment for weakness caused by disease
  • Support care is very important
  • Attention to respiratory system
  • Physical therapy to prevent scoliosis
interesting facts
Interesting facts
  • The second leading cause of Neuromuscular disease
  • People with SMA type I rarely live longer then 2-3 years
  • SMA is the number one genetic killer of children under the age of two.
