Genetic test was made with Sanger method. Non-dystrophic, non-syndromic myotonia with mild hypertrophy. Although next generation sequencing technologies and our bioinformatics analysis significantly reduce the contribution of pseudogene sequences or other highly-homologous sequences, these may still occasionally interfere with the technical ability of the assay to identify pathogenic variant alleles in both sequencing and deletion/duplication analyses. Genetic testing revealed a heterozygous missense mutation p.Q875E (c.2623C>G) of the SCN9A gene (NM_002977.2), which substitutes glutamine 875 by glu-tamic acid and which has not been previously described in patients with erythromelalgia (Figure 2).
