Two different models have been proposed to explain the observed difference in splicing between SMN1 and SMN2: loss of an enhancer or gain of a silencer. The first model proposes the existence in SMN1 of an ESE recognized by the SR protein SF2/ASF (UniProt accession number Q07955) (Cartegni...
Two highly homologous copies of SMN are present in SMA locus, namely, SMN1 and SMN2 [3], [4]. These two SMN genes are almost identical except for five nucleotide differences [3], [5]. A single nucleotide difference in exon 7 alters the splicing pattern of both genes, resulting in ...
In addition, the factors affecting the universal multiplex PCR were also examined and validated. The optimal condition was determined to be with the minimum amount of forward specific primer containing a universal section and a large difference in the annealing temperatures between the first and ...
universal fluorescent probe, connecting probe and recognizing probe to differentiate single nucleotide polymorphisms in UFTPL Our approach was based on the two UFTPL products of survival motor neuron I (SMN1) and SMN2 genes (the difference of 9 mer) and analyzed by capillary electrophoresis (CE)....
The critical sequence difference between the two genes is a single nucleotide in exon 7, which is thought to be an exon splice enhancer. Note that the nine exons of both the telomeric and centromeric copies are designated historically as exon 1, 2a, 2b, and 3-8. It is thought that gene...

SMN2, is highly homologous to SMN1 and lies within the same chromosome region 5q13 [1, 7]. Both SMN1 and SMN2 encode the SMN protein; however, the SMN2 gene has a nucleotide difference of 840C>T in exon 7 that affects the splicing pattern [...
“Analysis of subtle mutations inSMN1”described. In general,SMNtranscripts yielded three products, full-lengthSMN1(fl-SMN1, 1259 bp), full-lengthSMN2(fl-SMN2, 1259 bp) andSMN2isoform lacking exon 7 (Δ7-SMN2, 1205 bp). TheSMN1transcripts could be distinguished fromSMN2transcripts ...
The ex vivo splicing assay demonstrated that the variant disrupts inclusion of exon 7 (~85%) in the SMN1 mRNA; replacement with various bases yielded a variety of splicing effects in SMN1 and SMN2 pre-mRNA. The c.863G4T (r.835_*3del, p.Gly279Glufs*5) variant is located in a ...
