NCIt synonyms : BCD541; SMNC; Survival of Motor Neuron, Centromeric Copy Gene; C-BCD541; TDRD16B; GEMIN1; Survival of Motor Neuron 2, Centromeric wt Allele; Tudor Domain Containing 16B Gene;
NCIt definition : Human SMN2 wild-type allele is located in the vicinity of 5q13.2 and is approximately
29 kb in length. This allele, which encodes survival motor neuron protein, is involved
in the assembly of small nuclear ribonucleoproteins. Mutation of the gene is associated
with sporadic adult-onset lower motor neuron disease (LMND) and a modified form of
spinal muscular atrophy type 3.;
NCIt note : The SMN2 gene is part of a 500 kb inverted duplication on chromosome 5q13. The telomeric
and centromeric copies of this gene are nearly identical and encode the same protein.
