Fig. 1From: Genetic pattern of SMN1, SMN2, and NAIP genes in prognosis of SMA patients2% Agarose gel visualized by ethidium bromide showing, amplification of exon 5 of NAIP gene by multiplex PCR using exon 13 as an internal control. Lanes 1 and 4 showed no homozygous deletion. Lanes 2, 3, 5, and 6 showed homozygous deletion of exon 5Back to article page
