Inheritance pattern for most forms of SMA is autosomal recessive, meaning that both parents are carriers of the disorder, and the chance of having a child affected with the disorder is 25% with each pregnancy.

SMA (spinal muscular atrophy) is typically inherited in an autosomal recessive pattern. This means that a child must inherit a copy of the faulty gene from both parents in order to develop the condition. In some rare cases, SMA can be inherited in an autosomal dominant pattern.
