How To Remember Acral Dysostosis Dyserythropoiesis Syndrome Signs & Symptoms?

Acral dysostosis dyserythropoiesis (ADD) syndrome is a rare genetic disorder that causes abnormal bone growth, especially in the hands and feet.

It also causes anaemia, which is a low number of red blood cells, because erythropoiesis doesn’t work well (production of red blood cells). It is caused by changes in the VPS33B gene, which helps move molecules around inside cells.


Here are the signs and symptoms of Acral Dysostosis Dyserythropoiesis Syndrome :

  • Delayed bone growth and development
  • Increased risk of infections due to weakened immune system
  • Delayed motor milestones and difficulty with fine motor skills
  • Possible vision and hearing problems
  • Abnormally short fingers and toes (acral dysostosis)
  • Possible skin abnormalities and pigmentation changes.
  • Anemia (dyserythropoiesis)
  • Developmental delays and intellectual disability (in some cases)
  • Abnormal red blood cells (dyserythropoiesis)
  • Malformed nails and bones in the hands and feet
