According to the features of multicopies and highly homologous of SMN1 and SMN2 genes, which are similar to heteroplasmy or mosaicism, this study aimed to establish and evaluate a simple method for the relative quantification of SMN genes, as well as simultaneous screening of SMN1 subtle variations, based on Sanger DNA sequencing.
[41] A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay has been established for the diagnosis of SMA and it distinguishes the base differences in exons 7 and 8 SMN1 from SMN2 and is used to define homozygous deletions of SMN1 exon 7 and 8.

Deletion was detected in exon 8 area in SMN1 gene and SMA type 1 (Werdnig Hoffman disease) was diagnosed also considering postnatal age.

Alem da sindrome Spoan, foram descobertas tres outras doencas geneticas prevalentes nessa populacao, duas delas de heranca recessiva cuja manifestacao esta associada a endogamia: a amiotrofia espinal progressiva causada pela delecao dos exons 7 e 8 do gene SMN1 e distrofia muscular do tipo cinturas II-B (disferlinopatia).
UnKnown to them, both Amy and Daniel carry the faulty SMN1 gene which leads to the condition.
SMA is caused by a genetic defect in the SMN1 gene which codes SMN, a protein necessary for survival of motor neurons.
(4), (9) El cromosoma 5 tiene dos genes, SMN1 y SMN2 (SMN: Survival Motoneuron Gene).
The culprit in the disease is the survival motor neuron gene, called SMN1, which carries instructions for the crucial protein.
