The original version of this Article contained errors.

In the Material and methods section, under the subheading ‘Sanger sequencing’, an instance of the unit ‘μg/mL’ was incorrectly stated as “mL μg”.

“Cell lysis was performed at 55 °C for 30 min in lysis buffer (400 mM Tris/HCl, pH 8.0; 150 mM NaCl; 60 mM EDTA; 1% SDS) and 100/mL μg proteinase K.”

now reads:

“Cell lysis was performed at 55 °C for 30 min in lysis buffer (400 mM Tris/HCl, pH 8.0; 150 mM NaCl; 60 mM EDTA; 1% SDS) and 100 μg/mL proteinase K.”

Furthermore, due to repetition of adenine nucleotides at positions 865 to 869 of exon 9 in the RB1 gene, the authors could not specify the exact position of the frameshift insertion. The adenine nucleotide at the most 3’ position should have been assigned as the insertion following the 3' rule of the Human Genome Variation Society (HGVS) nomenclature standard. Additionally, the first amino acid change effected by the frameshift insertion, asparagine to lysine at position 290, was not correctly reported.

As a result, in the Results section, under the subheading ‘Germline mutation’,

“Germline mutation of frameshift insertion was observed in the coding region of RB1 gene at exon 9; NM_000321.3(RB1):c.874dup; p.(Tyr292Leufs*18) in heterozygous form. SIFT prediction indicated that this mutation caused an amino acid change from asparagine to leucine at position 290 on RB protein that induced premature stop codon with nonsense-mediated mRNA decay (NMD) (Fig. 1)29.”

now reads:

“Germline mutation of frameshift insertion was observed in the coding region of RB1 gene at exon 9; NM_000321.3(RB1):c.869dup; p.(Asn290Lysfs*20) in heterozygous form. SIFT prediction indicated that this mutation caused an amino acid change from asparagine to lysine at position 290 on RB protein that induced premature stop codon with nonsense-mediated mRNA decay (NMD) (Fig. 1)29.”

In the Discussion section,

“According to the whole genome sequencing results of the blood sample, we identified a mutation variant of the RB1 gene, c.864_865insA, that has not been reported in the COSMIC database.”

now reads:

“According to the whole genome sequencing results of the blood sample, we identified a mutation variant of the RB1 gene, c.869dup, that has not been reported in the ClinVar database.”

According to “NM_000321.3(RB1):c.869dup”, Figure 1 has been corrected. The original Figure 1 and accompanying legend appear below.
