BACKGROUND: Spinal muscular atrophy (SMA) is a common autosomal recessive neuromuscular disorder with the frequency of carriers in a number of ethnical groups ranging from 1/50 to 1/25. However, the prevalence of SMA for population of Ukraine remains to be established.
METHODS: For the analysis of deletion in exon 7 SMN1 gene in SYBR Green Real-Time qPCR assay specific for the single nucleotide change in exon 7 (cd 840 C >T) was used.
RESULTS: Using SYBR Green qPCR assay, the incidence of the exon 7 SMN1 deletion was established among 370 unrelated individuals without family history of SMA. The carrier frequency for this group of Ukrainians was estimated as 3.24% (1/31).
CONCLUSIONS: The results of our study showing the high prevalence of carriers warrant the importance of population screening for SMA in Ukraine.
