Yetong Chen changed review comment from: There is no sufficient evidence supporting a causal role of the COL4A2 gene in brain calcification. PMID 33247988 reports a patient with focal lesions with increased echogenicity in the right basal ganglia, which was suspected to result from either haemorrhage or calcification. However, the patient carries full duplications and deletions of COL4A1 and COL4A2, so it is likely that the brain calcification is not caused by COL4A2. PMID 33577044 summarises that 4 patients with COL4A2 developed brain calcification, including 1 case from PMID 21357838, 2 cases from PMID 30315939 and 1 from the present paper. This paper does not mention brain calcification found in the 2 reported cases. (Interestingly, there is a calculation mistake for the total number of patients with COL4A2 who had brain calcification. The sum should be 4 instead of 5.) None of the patients reported by PMID 21357838 carried COL4A2 variants nor developed brain calcification. Although PMID 30315939 reports 2 patients with COL4A2 variants, they did not show any sign of calcification.
