Variant summary

Our verdict is Benign. The variant received -12 ACMG points: 0P and 12B. BS1BP5_StrongBS2

This summary comes from the ClinGen Evidence Repository: The highest population minor allele frequency of the p.Gly126Ser variant in FOXG1 in gnomAD v4.1 is 0.0001782 in European (non-Finnish) population, which is higher than the ClinGen Rett and Angelman-like Disorders VCEP threshold (≥0.00008) for BS1, and therefore meets this criterion (BS1). The p.Gly126Ser variant is observed in at least 2 unaffected individuals (internal database - GeneDx) (BS2). The p.Gly126Ser variant is found in at least 3 patients with an alternate molecular basis of disease (internal database - GeneDx) (BP5_Strong). In summary, the p.Gly126Ser variant in FOXG1 is classified as benign based on the ACMG/AMP criteria (BS1, BS2, BP5_Strong).

Genes affected
FOXG1 (HGNC:3811): (forkhead box G1) This locus encodes a member of the fork-head transcription factor family. The encoded protein, which functions as a transcriptional repressor, is highly expressed in neural tissues during brain development. Mutations at this locus have been associated with Rett syndrome and a diverse spectrum of neurodevelopmental disorders defined as part of the FOXG1 syndrome. This gene is disregulated in many types of cancer and is the target of multiple microRNAs that regulate the proliferation of tumor cells. [provided by RefSeq, Jul 2020]

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Significance:Benign
Review Status:reviewed by expert panel
Collection Method:curation

The highest population minor allele frequency of the p.Gly126Ser variant in FOXG1 in gnomAD v4.1 is 0.0001782 in European (non-Finnish) population, which is higher than the ClinGen Rett and Angelman-like Disorders VCEP threshold (≥0.00008) for BS1, and therefore meets this criterion (BS1). The p.Gly126Ser variant is observed in at least 2 unaffected individuals (internal database - GeneDx) (BS2). The p.Gly126Ser variant is found in at least 3 patients with an alternate molecular basis of disease (internal database - GeneDx) (BP5_Strong). In summary, the p.Gly126Ser variant in FOXG1 is classified as benign based on the ACMG/AMP criteria (BS1, BS2, BP5_Strong). -
