There was an error in the original publication [1]. In patient 2 and 3, a mutation (p.Arg257Glu) is mistakenly documented. Instead, the mutation is p.Arg257Gln. A correction has been made to Section 2. Case Reports, 2.2. Case 2, Paragraph 3; Section 2. Case Reports, 2.3. Case 3, Paragraph 1; Section 3. Results, Paragraph 1; Section 4. Discussion, Paragraph 1:

Section 2. Case Reports, 2.2. Case 2, Paragraph 3: At the age of 10 years, genetic testing revealed previously described compound heterozygous variants in GCDH (p.Arg257Gln, p.Met405Val) [11,12], confirming the diagnosis of GA-1.

Section 2. Case Reports, 2.3. Case 3, Paragraph 1: After the diagnosis was made (compound heterozygous variants in GCDH: p.Arg257Gln and p.Met405Val), she was admitted during an infection with poor oral intake, and a clear deterioration of the movement disorder was observed.

Section 3. Results, Paragraph 1: Patients 2 and 3 were compound heterozygous for p.Arg257Gln and p.Met405Val, patient 1 was compound heterozygous for p.Gly241Val and p.Gly390Ala, and patient 4 was compound heterozygous for p.Arg257Trp and the novel variant p.Lys170Asn.

Section 4. Discussion, Paragraph 1: Patients 2 and 3 are compound heterozygous for a previously described severe mutation (p.Arg257Gln) with 0% residual activity [11] and a milder mutation (p.Met405Val) with 4–25% residual activity that is more prevalent in African patients [12].
