This article presents a retrospective study and a prospective study on spinal muscular atrophy in Oman. For the retrospective study, data were collected from neurophysiology records, from both inpatient and outpatient files. The prospective study was conducted on children as they presented to the hospital and was funded by Sultan Qaboos University. The patients of spinal muscular atrophy were classified into types I, II, and III based on their clinical features as per the International Spinal Muscular Atrophy Consortium classification. The incidence of spinal muscular atrophy was about 1 per 6000 live births. Spinal muscular atrophy type I formed 65% of the cases. Survival motor neuron deletion was seen in 70% of cases of all types of spinal muscular atrophy. The deletion was 83% in spinal muscular atrophy type I. A further study to look into the nondeletional cases is in progress.
