Fig. 3From: Prenatal diagnosis identifies compound heterozygous variants in RYR1 that causes ultrasound abnormalities in a fetusA Minigene splicing assay. The WT higher band represented correctly spliced exons, whereas the MT lower band represented the RYR1 deletion 105 bp in exon 21. Sequencing revealed the MT-type was missing the entire exon 21 sequence due to the c.2682G > C variant. B Conservation analysis. The residue Arg4191 was highly conserved among nine different speciesBack to article page
