The aim of this study was to determine association between the SMN2 gene copy number and disease phenotype in Serbian patients with SMA with homozygous deletion of exon 7 of the SMN1 gene.MethodsThe patients were identified using regional Serbian hospital databases. Investigated clinical characteristics of the disease were: patients' gender, age at disease onset, achieved and current developmental milestones, disease duration, current age, and the presence of the spinal deformities and joint contractures. The number of SMN1 and SMN2 gene copies was determined using real-time polymerase chain reaction (PCR). RESULTS. Among 43 identified patients, 37 (86.0%) showed homozygous deletion of SMN1 exon 7. One (2.7%) of 37 patients had SMA type I with 3 SMN2 'copies, 11 (29.7%) patients had SMA type II with 3.1 +/-0.7 copies, 17 (45.9%) patients had SMA type III with 3.7 +/-0.9 copies, while 8 (21.6%) patients had SMA type IV with 4.2 +/-0.9 copies. There was a progressive increase in the SMN2 gene copy number from type II towards type IV (p < 0.05). A higher SMN2 gene copy number was associated with better current motor performance (p < 0.05).ConclusionIn the Serbian patients with SMA, a higher SMN2 gene copy number correlated with less severe disease phenotype. A possible effect of other phenotype modifiers should not be neglected."xsd:string |
