ClinGen Brain Malformations Variant Curation Expert Panel RCV001837024 SCV001949954 likely benign Overgrowth syndrome and/or cerebral malformations due to abnormalities in MTOR pathway genes 2022-02-12 reviewed by expert panel curation The c.6440A>C (NM_004958.4) variant in MTOR is a missense variant predicted to cause substitution of (p.Asn2147Thr). The highest population minor allele frequency in gnomAD v2.1.1 is 0.0006495 in European (Finnish) population, which is higher than the ClinGen BMEP threshold ([>0.00037]) for BS1, and therefore meets this criterion (BS1). MTOR, in which the variant was identified, is defined by the ClinGen Brain Malformations Expert Panel as a gene that has a low rate of benign missense variation and where pathogenic missense variants are a common mechanism of disease (PP2). In summary, this variant meets the criteria to be classified as Likely benign for mosaic autosomal dominant overgrowth with or without cerebral malformations due to abnormalities in MTOR-pathway genes based on the ACMG/AMP criteria applied, as specified by the ClinGen Brain Malformations Expert Panel: BS1, PP2; -3 points (VCEP specifications version 1; Approved: 1/31/2021)
