In the published article, there was an error in “Table 1” as published. We are correcting the error in the original Table 1, i.e., the p.R164Q mutation we reported should be corrected as p.Y157H. The corrected “Table 1” and its caption “The clinical presentations and genetic analysis of four CMT probands” appear below.

TABLE 1

Table 1. The clinical presentations and genetic analysis of four CMT probands.

In the published article, there was an error. The mutation p.R164Q we reported should be corrected as p.Y157H. A correction has been made to “Pages 1, 4, 6, and 12”.

This sentence previously stated:

Page 1. Abstract

“Using targeted exome-sequencing, we investigated four CMT families from central-southern China and identified two novel missense variants (p.F31S and p.W44G) and two previously reported variants (p.R220Pfs^*23 and p.R164Q) of GJB1.”

Page 4. Results section, paragraph 1

“After tering and validation by Sanger sequencing, four probable pathogenic variants, including two variants previously reported as pathogenfilic variants (c.469T>C, p.R164Q, Li et al., 2016 and c.657dupC, p.R220Pfs^*23) (Lu et al., 2017) and two novel variants (c.130T>C, p.F31S and c.92T>C, p.W44G), were identified in four CMT families (Figure 1).”

Page 6, right column, paragraph 1

“The proband 4 (III:2) was a 28-year-old male, carrying the p.R164Q variant in GJB1, who presented with right lower limb weakness at the age of 15.”

Page 6, right column, paragraph 2

“Since functional alternation by R164Q variation has been briefly explored previously (Li et al., 2016), we have not included this mutation in our study.”

Page 12, Discussion section, paragraph 1

“Using targeted exome-sequencing, we identified two known GJB1 mutations (p.R164Q and p.R220Pfs^*23) and two novel pathogenic variants in GJB1 (p.F31S and p.W44G) among four CMT families in central-southern China. F31S and W44G were first found in our cohort, expanding the mutation spectrum in GJB1-CMT1X.”

Page 12, Discussion section, paragraph 1

“Both variations of R164Q and R220Pfs^*23 have been previously reported, whereas only the R164Q mutation has been briefly explored functionally in vitro.”

The corrected sentence appears below:

“Using targeted exome-sequencing, we investigated four CMT families from central-southern China and identified two novel missense variants (p.F31S and p.W44G) and two previously reported variants (p.R220Pfs^*23 and p.Y157H) of GJB1.”

“After filtering and validation by Sanger sequencing, four probable pathogenic variants, including two variants previously reported as pathogenic variants (c.469T>C, p.Y157H, (Li et al., 2016) and c.657dupC, p.R220Pfs^*23) (Lu et al., 2017) and two novel variants (c.130T>C, p.F31S and c.92T>C, p.W44G), were identified in four CMT families (Figure 1).”
