What is the prevalence of Spinal muscular atrophy with respiratory distress type 1?

Spinal muscular atrophy with respiratory distress type 1 (SMARD1) is an extremely rare genetic disorder that affects the nerves controlling the muscles involved in breathing and movement. It is characterized by progressive muscle weakness, respiratory distress, and early onset of symptoms, typically appearing within the first few months of life.

Due to its rarity, the prevalence of SMARD1 is not well-documented. However, it is estimated to affect fewer than 1 in 1,000,000 individuals worldwide. The condition is inherited in an autosomal recessive manner, meaning that both parents must carry a copy of the mutated gene for their child to be affected.

SMARD1 is caused by mutations in the IGHMBP2 gene, which is responsible for producing a protein essential for the survival and function of motor neurons. The loss of function of this protein leads to the degeneration of motor neurons, resulting in muscle weakness and respiratory difficulties.

Early diagnosis and intervention are crucial for managing SMARD1. Treatment options are limited, and supportive care is primarily focused on addressing respiratory complications and maintaining quality of life. Research efforts are ongoing to better understand the condition and develop potential therapies.
