Figure Description

In the original publication [1], there was a mistake in the legend for Figure 1. Heterozygous variant in the NOTCH3 gene, chr19:15192257 T>G.

The correct description appears below.

Correct description of Figure 1:

The authors corrected the name of the NOTCH3 genetic variant (chr19:15192257 T>G). The authors also updated the Varsome website (to 13 December 2023).

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.

Error in Table

In the original publication, there was a mistake in Table 4. Genetic variants of the NOTCH3 gene and the clinical characteristics of patients with CADASIL as published.

Table 4 included an error regarding a NOTCH3 genetic variant name (chr19:15192258 G>T) and its localization (exon 4, codon: 127) and coded protein (proline). The clinical significance described as not described in the literature was also incorrect.

The corrected Table 4. Genetic variants of the NOTCH3 gene and the clinical characteristics of patients with CADASIL appears below.

The authors corrected the NOTCH3 genetic variant name, localization, and protein (chr19:15192257 T>G, exon 4, codon: 128, cysteine). The authors also corrected the clinical significance of this genetic variant—the clinical significance has not been confirmed in the literature so far. The characterization of the patient’s headache remained the same.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.

Missing Citation

In the original publication [1], Coto, E.; Menéndez, M.; Navarro, R.; García-Castro, M.; Alvarez, V. A new de novo Notch3 mutation causing CADASIL. European Journal of Neurology 2006, 13, 628–631 was not cited.

The citation has now been inserted in the Discussion section and References section and should read as follows:

The chr19:15192257 T>G variant was first reported by Coto et al. in 2006 [75]. The authors describe a 44-year-old patient with CADASIL symptoms, in whom this genetic variant was confirmed. Interestingly, the authors emphasize that the parents of this patient were neurologically healthy and did not carry this mutation. They also emphasize the need for further analyses of NOTCH3 gene variants in people with CADASIL symptoms but with a family history. Despite reporting a new mutation in exon 4 of the NOTCH3 gene, Coto et al. [75] did not provide a detailed clinical picture of the patient with this change. In our study, we described the patient’s CADASIL picture depending on the type of headache that was one of the symptoms.

The authors added information about chr19:15192257 T>G from the first publication by Coto et al. in 2006.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.

Text Correction

There were errors in the text of the original publication. In the text of the Abstract, Results, and Discussion sections, there were mistakes in the genetic variant’s name, its localization, and coded protein. Because of the sequencing error, there were also mistakes in the Varsome interpretation.

A correction has been made to the following:

1. Abstract section

We described three variants as pathogenic/likely pathogenic (p.Tyr189Cys, p.Arg153Cys, p.Cys144Arg) and two benign variants (p.Ala202=, p.Thr101=) in the NOTCH3 gene and also presented the NOTCH3 gene variant (chr19:15192257 T>G). Clinical features including headache associated with NOTCH3 (chr19:15192257 T>G) are described for the first time.

The authors corrected the NOTCH3 gene variant name and added information about its data in the literature—this variant was only reported in one publication, but the authors added a specific clinical characterization of this variant.

Moreover, we identified the NOTCH3 gene mutation (chr19:15192257/c.382T>G p.Cys128Gly), displayed in Figure 1, which has only been mentioned once as a “de novo mutation” in CADASIL patients in the literature to date, but this is the first time we have described the clinical features including headache associated with this variant.

According to the Varsome database (accessed on 13 December 2023), the variant chr19:15192257 T>G of the NOTCH3 gene, identified in exon 4, is located in codon 128 and encodes a cysteine [48].

The chr19:15192257 T>G variant was found in one patient (female, 45 years old) who reported episodes of MO from the age of 34 (>10 years of MO).

The authors corrected data about the chr19:15192257 variant. The authors corrected its localization and change in the protein. The authors also added the information that this variant was not described in a clinical way.

Three pathogenic/likely pathogenic variants, two benign variants, and one variant of the NOTCH3 gene (chr19:15192257 T>G) have been reported in the literature [48], but the detailed clinical significance last variant and clinical picture of a patient with this variant has not been presented.

The authors corrected the genetic variant name.

The chr19:15192257 T>G variant was first reported by Coto et al. in 2006 [75]. The authors describe a 44-year-old patient with CADASIL symptoms, in whom this genetic variant was confirmed. Interestingly, the authors emphasize that the parents of this patient were neurologically healthy and did not carry this mutation. They also emphasize the need for further analyses of NOTCH3 gene variants in people with CADASIL symptoms but with a family history. Despite reporting a new mutation in exon 4 of the NOTCH3 gene, Coto et al. [75] did not provide a detailed clinical picture of the patient with this change. In our study, we described the patient’s CADASIL picture depending on the type of headache that was one of the symptoms.

A patient with a chr19:15192257 T>G genetic variant of the NOTCH3 was diagnosed with MO.

The authors added information about chr19:15192257 T>G from the first publication by Coto et al. in 2006.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.

References

The authors corrected references. The authors updated the Varsome database website to 13 December 2023 and updated the website’s link.

The authors also added the 75th publication as a reference where the chr19:15192257 T>G variant was mentioned first:

With this correction, the order of some references has been adjusted accordingly. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
