Abstract
Spinal muscular atrophy (SMA) is an autosomal recessive inherited motor neuron disease characterized by progressive muscle weakness due to degeneration and loss of the anterior horn cells in the spinal cord and the brain stem nuclei from foetal life through infancy and childhood. SMA is prevalent in Ghanaian children, though not widely reported. Cases are likely missed or misdiagnosed due to lack of expertise and investigations. Newborn screening is not currently available in Ghana. The management remains supportive as newly approved genetic modifications therapies are currently not available. We present a retrospective folder review of children attending a tertiary pediatric neurology clinic who were diagnosed with SMA and confirmed by molecular genetic testing. Between January 2018 and August 2021, five (5) children from three families had molecular genetic tests confirming their diagnosis of SMA. Three (3) children had SMA I phenotype while 2 had SMA III phenotype. Two (2) of the 3 children with SMA I died from respiratory complications. The last surviving child with SMA I was diagnosed through newborn screening program overseas and received gene modification therapy. Careful history and physical examination remain the best approach to diagnosis as confirmatory genetic testing and supplemental investigations are not readily available. The current management of the children with SMA in Ghana include respiratory care, physiotherapy, and genetic counselling. Genetic modification therapies are currently not available.
